2.2.1 Control Symbols
The Braille Sense U2 MINI uses several control symbols to note the type of information being displayed: examples are list items, menus, and edit boxes. These symbols can appear "Before" or "After" the text, or the appearance of this information may be set to "off". The way this information is displayed is determined by the "Control information" setting in the "Global Options" dialog. The default value is set to "Before." Note: In the Web Browser, the control symbols are displayed even if the "Control information" is set to "off".

As explained above, the control symbol appears before or after the text of the control. For example, if "Control information" is set to "before", and you bring up the Word Processor's program menu, The Braille Sense displays, "MN File (f) pulls down".


The following table shows the types of controls and the symbols that are used to indicate them.



Name

Symbol

Comments

Menu

MN

It means the menu has submenus.

Menu item

MI

It means the menu does not have a submenu.

List item

LI

The item name after this symbol represents the name of the item in any list.

(Ex: “LI database” or “LI sample.txt” in the “file list” of the file manager)



Edit box

EB

The item name after this symbol represents the edit box name. You can find the edit box after the edit box name. In the web browser, the symbol “EB” may be followed by an edit box without an edit box name. Edit boxes that begin with the symbol “EB” are one line.

(Ex: “EB Last name: (cursor)” in the address manager program or “EB (cursor)”



Multi edit box

MEB

This also represents the edit box. But you can type in more than one line in the edit box.

(Ex: “MEB Subject: (cursor)” in the e-mail program)


Computer edit box


CE


It means there is an edit box to input ASCII Braille.

The edit box after this symbol should allow ASCII Braille to be typed in.

(Ex: “CE To: (cursor) “ in the email program)


Combo box

CB

It represents the combo box in which you can choose an item by pressing the up scroll button or the down scroll button.

(Ex: “CB Type: *.*” in the “Open dialog box” of the word processor program)



Edit combo box

ECB

You can choose the desired item by pressing the up or down scroll button, or by directly typing in the item name.

(Ex: “ECB File name: (cursor) “ in the “Open dialog box” of the word processor program)



Prompt button

PB

PB follows any question in which you have to choose “Yes” or “No.” You can toggle between “Yes” and “No” by pressing the “Space” or the “Backspace” button.

(Ex: When you exit from the word processor, “PB Save: Yes”)



Static box

ST

ST is followed by the current status.

(Ex: “ST noname.hbl/insert mode/write” in the word processor program)



Link

LN

It means there is a link in the web page.

Anchor

ANC

It means there is an anchor in the web page.

Radio button


RB


It represents a radio button, which allows you to choose an item by pressing the up scroll button, down scroll button, space, or Backspace. Also it cycles between items when pressing this key.

(Ex: “RB Attribute: Write” in the “Information dialog box” of the file manager)



Radio button select

SRB

It means that the radio button is selected in the web browser

Radio button unselect

URB

It means that the radio button is not selected in the web browser.

Check box check

SCHB

It means that the check box is selected.

Check box uncheck

UCHB

It means that the check box is not selected.

Note: Links, anchors, and radio buttons are controls that are only used in the Web Browser.


The symbols enable you to understand what type of input control or menu you are working with. For example, if "MN," "MI," or "LI" are displayed, you know you can move from one item to the previous and next items by pressing the "Up" and “Down" scroll keys. If "ECB," "EB," "CB," or "MEB" are displayed, you know you are in an input area where you must type the desired text. If "BT" is displayed, you can press "Enter" to activate the "button".
2.3 Using the Function Keys
There are four function keys on the Braille Sense U2 MINI. You can use these function keys to open the menus, cancel tasks, and move to other items.

As described previously, the "F1" key opens the Braille Sense U2 MINI "Program" menu from anywhere on the unit. You can also use "F1" and a program's shortcut key to open that program from anywhere on the Braille Sense U2 MINI. For example, if you are in the Word Processor, and want to open the Web Browser, you could press "F1-b (dots 1-2)" to open the Web Browser.

From within each program, the "F2" key opens the program specific menu. Note: as previously explained, you may also use "Space-m (dots 1-3-4)" to perform this function.

The "F3" key has the same function as "tab ("Space-4-5"). "Space-F3" serves the same function as pressing "shift-tab ("Space-1-2")."

The "F 4" key functions as the "escape" key does on a personal computer. You can also use "Space-e (dots 1-5)" to perform this function. Please note that the "escape" key does not exit a program, as does "Space-z (dots 1-3-5-6)", but rather, exits items menus, dialogs, or prompt boxes.

You can use the function keys in combination to perform various other tasks. Pressing "F1" and "F2" at the same time functions as "page up" on a personal computer. Pressing the "F3" and "F 4" keys together serves as "page down". The combination of "F1" and "F 4" moves you to the task list (similar to the task bar in Microsoft Windows). Pressing the "F2" and "F3" keys simultaneously cycles you through the running programs; similar to pressing "alt-tab" on your PC. The Task List and task switching are explained in greater detail in section 2.9, "Multitasking".


2.4 The AC Power Supply and the Battery Pack
It is often useful to know the remaining battery power on the Braille Sense U2 MINI so you can determine how much time you have before you must change the battery or connect to AC power. If the remaining battery power falls below 15 percent, the Braille Sense U2 MINI indicates the battery power is low.
To check the battery power status, press "Space-1-6." The unit displays the following 2 items:

1. Battery power level

2. Power source (battery or AC power)
The battery power level represents the percentage of the remaining battery power. The power source indicates whether the unit is being operated using the battery or the AC power supply. If the battery power level drops under 15 percent, the Braille Sense U2 MINI displays the battery status on the Braille display, and it announces that the battery has less than 15 percent of its power remaining. If the battery power level falls below five percent, the Braille Sense U2 MINI gives you a warning indicating that your battery power level is under five percent, and the Braille Sense U2 MINI will be automatically turned off in one minute, unless you connect it to an AC power supply.

Let's explore the detachable battery pack. When the Braille Sense U2 MINI is shipped, the battery pack is not installed. This is done to prevent damage during shipping. When you insert the battery in to the Braille Sense U2 MINI for the first time, the unit may display an inaccurate battery power level. Before using the Braille Sense U2 MINI for the first time, please charge the battery for at least 2 hours. You may use the unit during the initial charge, however, it is recommended if you do, that the unit remain connected to AC power for at least 2.5 hours to fully charge the battery.

When you remove the battery from the Braille Sense U2 MINI, make sure your unit is turned off; especially when the AC power adapter is not connected. If you remove the battery while the unit is on and AC power is not connected, you will lose all data stored in RAM, including open documents, emails, and contacts or appointments that have not been backed up. If you remove the battery, and do not have the Braille Sense U2 MINI connected to AC power, the data stored in RAM remains for about 1 hour. To save your RAM data the Braille Sense U2 MINI must be connected to an AC power adapter or battery pack within an hour; or this data is lost.
[Note, when using CD-ROM/external hard drives]

*When you connect an external CD-ROM drive to the Braille Sense U2 MINI, please use the AC power adapter for the CD-ROM. It takes about one minute for the CD-ROM to be recognized by the Braille Sense.


[Note, when charging via USB:]

*Braille Sense U2 MINI can be charged via a USB cable. However, charging with a USB cable supplies less power to the Braille Sense U2 MINI than does the AC adapter. While charging Braille Sense U2 MINI via USB, if you use the unit continuously, the battery may not charge, or, depending on how much power you are using, the battery may even continue to drain. If you want to charge the Braille Sense U2 MINI via a USB cable, it is recommended that you leave the unit powered off while charging.

*If you use a USB cable other than the one shipped with the unit, the Braille Sense U2 MINI may not recognize external USB devices or may not be charged. Please always use the USB cable which is provided with the Braille Sense U2 MINI.

2.5 Basic Explanation of Disks, folders, and files
Think of the flash memory on the Braille Sense U2 MINI like a big bookshelf in a library. You can create partitions on a bookshelf to organize books into categories. Think of the "folders" on the Braille Sense U2 MINI as being similar to these categorical partitions. The books in each section can be compared to the "files" on the Braille Sense U2 MINI. You can save files into any folder at your discretion. If you create meaningful folder names and properly organize your files into them, it will make for easier retrieval of files when you need to access them later.

When the Braille Sense U2 MINI is shipped from the factory, the name given to the flash memory in the Braille Sense U2 MINI is "flashdisk". You can create folders on this "flashdisk" in any way that you prefer.

You can also expand your available storage by adding additional storage devices, such as a Secure Digital card or USB flash drive. The Secure Digital card is named, "sd". A USB flash drive appears as "USB." If you decide to add any of these memory devices, you can create folders, and save files on them just as you can the flashdisk.
2.6 Controlling the Volume, Speed, and Pitch of the TTS
You can change the volume, speed, and pitch of the voice used on the Braille Sense U2 MINI. Press "Backspace-F 4" to increase the volume. Press "Backspace-F1" to decrease the volume. Press "Space-F 4" to increase the speech rate. Press "Space-F1" to decrease the speech rate. Press "Enter-F 4" to raise the pitch and "Enter-F1" to lower it.

When you press any of the above key combinations, the Braille Sense U2 MINI announces the status of its volume, rate, or pitch. The changes in the characteristics of the voice remain in effect until you change them again, or a hard reset is performed either manually or due to lack of power to the unit for an extended period of time.


Note: the volume of the voice is controlled independent of the master volume on the unit, thus, you can adjust it above or below the volume of the system sounds, media playback, etc using the Voice volume control described above. You can control the master volume or “Main Volume” of the unit using “Backspace-Enter-F1” to lower it and “Backspace-Enter-F4” to raise it.
You can also control the rate of the foreign language TTS voice independent of the main speech rate. You can adjust the TTS for other languages, the “Sub Voice rate”, in the “Global Options” dialog or by pressing “Space-Enter-F1” and “Space-Enter-F4”.
2.7 Using Speech and Braille
When using the Braille Sense U2 MINI, you can choose to read using Braille only or speech only. You can also use both Braille and speech simultaneously. However, you cannot turn off both Braille and speech as you would have no method of receiving information from the Braille Sense U2 MINI. Use "Backspace-F2" to toggle the speech on and off. Press "Backspace-F3" to toggle the Braille on and off. Please refer to section 3.2.1 in this user manual for more information.
2.8 Entering Text
In a document, "edit box" or "multi edit box" on the Braille Sense U2 MINI, you can enter either grade 1 or grade 2 Braille. However, some areas of the unit, such as the "to" field of the E-mail program, contain a "computer edit box" requiring you to enter text in computer Braille. To enter a capital letter in computer Braille, use the upper case indicator (Space-u (dots 1-3-6)" before the letter you want capitalized. For example, if you want to enter H in a computer edit box, press "Space-u (dots 1-3-6)" then "dots 1-2-5". If you press "Space-u" twice, caps lock is turned on. Press "Space-u" again to turn off caps lock.

You can also press "Space-Backspace" simultaneously with the letter to capitalize it. To input the "at sign," you must use one of these capitalization methods in conjunction with the dot 4. You may either use "Space-u" followed by dot 4, or "Space-Backspace-dot 4".


To enter numbers in contracted or uncontracted Braille, use the "number sign (dots 3-4-5-6)" followed by the number. However, when using computer Braille, you use no number sign and must enter numbers as "dropped" numbers or Nemeth numbers.

2.8.2 Inputting/searching for Control characters

Control characters are codes in a character set, which do not in themselves represent written symbols in computing. For example, all entries in the ASCII table below code 32 such as Form Feed (FF), TAB, and Carriage Return (CR). You can input and search for control characters in Braille documents.


2.8.2.1 Inputting Control characters
Control characters can only be entered in Braille documents. To enter control characters in Braille documents, follow these steps.
(1) From within a Braille document, press "Space-x (dots 1-3-4-6)". "Control character" is announced to alert you to the fact that the next character you enter should be a control character.

(2) Enter the control character. For example: "l (dots 1-2-3)" for Form Feed (FF) or "i (dots 2-4)" for TAB in alphabetical order.

(3) The control character is entered into the Braille document.
2.8.2.2 Searching for a Control character
You can also search for control characters in Braille documents. To search for a control character, follow these steps.
(1) From within a Braille document, press "Space-f (dots 1-2-6)".

(2) "Text to find" is displayed.

(3) Press "Space-x (dots 1-3-4-6)". "control character" is announced.

(4) Enter the control character for which you want to search.

(5) Press "Enter" to search for the control character.
2.9 Multitasking
Unique to the Sense notetakers is their ability to run up to seven tasks at once. The ability to run multiple applications simultaneously is referred to as multitasking. For example, you can work with the Word Processor while listening to music, and place calculations into a document at the same time. To continue with the example of the Word Processor and Media Player, open the Media Player and play a music file. While the audio is playing, press the "F1" key to bring up the "Program" menu and launch the Word Processor.

You cannot run more than seven applications at the same time. If you try to run a program that is currently running, The Braille Sense U2 MINI does not open a new instance of the program, but rather, returns you to the instance of the program that is already running. For example, while working with a document called "Notes" you decide to execute the "File Manager." Next, you navigate to a document called "journal" in the file list and press "Enter." The Word Processor does not load a second time, but rather, "journal" is opened in the same instance of the Word Processor in which "notes" is already loaded. You can switch among multiple open documents in a single instance of the Word Processor. Use "Tab (Space-4-5 or F3)" or "shift-tab (Space-1-2 or Space-F3)" to cycle forward or backward through the currently open documents. Switching documents is explained in more detail in section 4, which covers the Word Processor.

If you have pressed "F1" to bring up the "Program" menu, or "F1-F 4" to open the Task List and you decide not to access a different application, you can press "escape" ("Space-e" or "F 4") to return to your previous location on the unit. To switch between currently running programs press "F1-F 4" to open the Task List. The Task List shows all the currently running programs in list form. To return to any application, simply navigate to it and press "Enter".

You can use "F2-F3" to immediately cycle among all running programs without opening the Task List. This is similar to using "alt-tab" on your PC. If you are running three programs and are in the second program, pressing "F2" and "F3" moves you to the third program. If you press "F2-F3" again, you are placed in the first program.

In the above case, if you were to press "Space-z (dots 1-3-5-6)" to close the currently open program, you are then placed in the previous program. However, if there is only one program running, pressing "Space-z" closes the program and places you in the "Program" menu.
2.10 Switching Media Modes
The media buttons on the front panel perform different functions according to the location of the "Media Mode" switch.

If you slide the "Media Mode" switch to the left-most position, the Braille Sense U2 MINI announces, "radio mode" and the media buttons control operation of the FM Radio. If you place the "Media Mode" switch in the center position, the Braille Sense U2 MINI says, "DAISY mode" and the media buttons control playback of Daisy content. If you slide the "Media Mode" switch to the right-most position, the Braille Sense U2 MINI announces, "media mode" and the media buttons control media playback.

It is very important to pay attention to the position of the "Media Mode" switch to achieve desired operation of the media buttons. For example, if you are using the Media Player, if the "Media Mode" switch is placed in the left-most position, the media buttons on the front panel control operation of the FM Radio even though your focus is in the Media Player. More detailed explanations of the functions of the Media buttons is given in the FM Radio, Daisy Player, and Media Player sections in this manual.
2.11 Switching Key lock
You can disable the keys on the Braille Sense U2 MINI to prevent the accidental pressing of keys using the key "Lock" switch on the left panel.

When the key "Lock" switch is placed in the position nearest the rear of the unit, Braille Sense U2 MINI announces, "All keys locked". This means all keys on the unit are disabled including the on/off switch. If the key "Lock" switch is placed in the center position, Braille Sense U2 MINI says, "top panel locked". This means you can continue to use the buttons and switches on the front panel (media mode switch, media buttons and on/off switch), however, you cannot use any of the keys on the top face of the unit. If the key "Lock" switch is placed in the position nearest the front of the unit, Braille Sense U2 MINI announces, "unlocked". This indicates all keys are operational (Braille keyboard, media buttons, scroll keys, function keys, Media Mode switch and On/Off switch).

Note: the "RESET" button is always operational, regardless of location of the key "Lock" switch.
If you want to lock and unlock only the keys on the front media panel, you can do this by pressing the “Back” and “Forward” media buttons simultaneously. If you press “Back-Forward” the unit announces “Media keys locked”, and the media panel does not respond to key presses. If you press the keys again, the unit announces “Media keys unlocked”, and the media buttons are again operational.
2.12 Print Spool
The Braille Sense U2 MINI has a print spool function. This function enables the Braille Sense U2 MINI to do other tasks while printing to an ink-printer or Braille embosser. For example, if you send data to your printer or embosser, you are immediately returned to where you were before the print command was executed. If you want to check the Print Spool dialog box after you have given the print command, press "Space-2-3-4-6." A dialog box appears with three controls: a list containing information about files that are being printed, a "Cancel" button, and a "Close" button. You can cycle through the three controls by pressing "tab (Space-4-5)" or "shift-tab (Space-1-2)." In the information list, you can move among the items by pressing "Space-4" or "Space-1." If you open the dialog box when nothing is printing, "no items" appears in the list and only the "Close" button is available.

While printing, the information list contains the following: "running program name," "printing file name," "printer type," "the number of copies," and either "printing" or "ready." For example, let's assume that we are printing one copy of "sample.txt" from the Word Processor. The info list displays, "program: Word Processor, file: sample.txt, printer, copy: 1, printing." If you are using a Braille embosser, "embosser" appears instead of "printer." If nothing is printing but, (the printer is waiting), "ready" is displayed instead of "printing." If you print something from the E-mail program, "emailtemp.txt," is displayed instead of the file name. If you are printing from the Address Manager, or the Schedule Manager, the message, "prn_ggtimegg.txt" is shown.


If you focus on a file in the info list, pressing "Enter" on "Cancel" cancels the printing of that file. If you tab to "Close," and press "Enter" the Print Spool dialog box is closed. Pressing "Space-z (dots 1-3-5-6)" also closes the Print Spool dialog.
2.13 One-Handed Mode
Braille Sense U2 MINI provides a One-handed mode for users restricted to the use of one hand for Braille input. To turn on One-handed mode, hold down "F3" while powering the unit on. To turn off One-handed mode (i.e. to return to two-handed mode), hold down "F 4" while powering on the unit. You can also turn One-handed mode on or off in the "Global Options" dialog.

When One-handed mode is on, use the following methods to input text:

1. To type a character, press the dots in any combination or order. When you have pressed all dots, press "Space" to complete the entry of the character. For example, if you want to type "h," you press "dot 1" and "dot 2" separately or together and then press "dot 5." Finally, press "Space".

2. To press a command that includes "Space," press "Space" both before and after the dot combination. For example, to press "Space-o (dots 1-3-5)," press "Space" then press "dot 1", "dot 3" and "dot 5" separately or together in any order. Then press "Space" again.

3. To press a command that includes "Backspace" or "Enter," press "Backspace" or "Enter" before the dot combination. Then press keys that make up the dot combination. Finally press "Space". For example, to press "Enter-l (dots 1-2-3)", press "Enter", and then press "dots 1-2-3." then, press "Space".

4. To press "Space," "Backspace" and "Enter", press the key twice. For example, to press "Space" to create a space between words, press "Space" twice.


The operation of the scroll keys, function keys, and media buttons remains the same as in normal mode.

If One-handed mode is on, the Braille Sense U2 MINI announces this each time it is powered on, as well as how to return to normal operation.


2.14 Using Typing Mode
While you are typing in a document, you may wish to turn off the navigation keys, especially if you type very fast as you may accidentally navigate when you intend to enter text. To turn on "Typing Mode",

follow these steps:

(1) Press "Backspace-Enter-c (dots 1-4)", from within a document.

(2) "Start typing mode" is announced and displayed.


When using "Typing Mode", if you press "Space-dot 4", instead of moving to the next line, the "Space" and "Dot 4" are entered into the document.

To cancel "Typing Mode", follow these steps:

(1) Press "Backspace-Enter-c (dots 1-4)" when in "Typing Mode".

(2) "End typing mode" is announced and displayed.



After "Typing Mode" is canceled, pressing "Space-dot 4" once again moves you to the next line as you would expect.

When you finish typing the pin code, press "Enter". The unit announces, "Please wait for authentication". If the remote device is setup correctly, and has not been set up to allow this device to always connect, the remote device also asks for a pin code. Please be sure to enter the same pin code on both devices. If the remote Bluetooth device pin code matches the pin code on the Braille Sense U2 MINI, the service should authenticate. If connection is successful, the unit announces, "PIN code authentication accepted".

You are then prompted, "Please wait. Access permission". If the remote Bluetooth device does not give access permission, the unit says, "Connection failed", and you are returned to the Bluetooth Services List. If the remote Bluetooth device gives you access permission, the Braille Sense U2 MINI says "Connection succeeded". If the connection succeeds, "Connected" is displayed after the service in the Bluetooth Service List. Some services may be connected without inputting a pin code depending on the Remote Bluetooth device settings.

When you are connected to a service, you can press "Enter-d (dots 1-4-5)" to disconnect the service. The Braille Sense U2 MINI says, "Service disconnected", and you are returned to the Bluetooth Service List.

If you connect to the FTP service, a list of files and folders on the remote Bluetooth device is displayed. The rest of this chapter discusses each service in detail.
3.3.2.2 LAN Service
You can use the LAN service to access the Internet via your computer's Internet connection. If you connect this service, you can use the Web browser and email program, as if you were connected to the Internet via Ethernet or wireless LAN. Before you can connect to the LAN service on a remote Bluetooth device, the device must be configured for Internet Connection Sharing (ICS). If ICS is not properly setup, you cannot connect to the Internet using the LAN service. For information on how to setup ICS for your remote Bluetooth device, please refer to the documentation that came with your Bluetooth adapter. Setting up ICS requires knowledge of network architecture, so it may be a good idea to contact a local network technician or your network administrator for help with setting up ICS.
3.3.2.3 FTP Service
This service works similarly to using FTP on the Internet. It allows you to transfer folders and files to and from the remote Bluetooth device. When referring to the FTP service, we will refer to the file/folder list on the remote Bluetooth device as the "remote folder list" and the file/folder list on the Braille Sense U2 MINI as the "local folder list".

After you have successfully connected to the FTP service, the Bluetooth Manager places you in the remote folder list. The remote folder list displayed is determined by the remote Bluetooth device. Typically, this folder is called the Bluetooth Exchange Folder, but you should check your remote Bluetooth device documentation for definitive information.

You can interact with the remote folder list in much the same way as you interact with files and folders in the File Manager. With the FTP service, you can perform the following functions:

1. Copy


2. Paste

3. Send To

4. Retrieve File

5. New Folder

6. Delete File/Folder

7. Open Local Folder. If you press "Enter" on this option, you are taken to the local folder list. If you are in the local folder list, this menu option changes to "Move to remote folder".

8. Select All

9. Information


In the next few sections, we will discuss the various FTP functions. Please note that while sending data to and from the remote Bluetooth device, the remote Bluetooth device may still need to give access permission to the Braille Sense U2 MINI. Please consult the documentation for the remote Bluetooth device for details.
