1.4 Physical Orientation
To get the most from your Braille EDGE 40, it is important to become
oriented to the buttons on your Braille EDGE 40 as well as learning their
functions. This section explains the physical configuration of the Braille
EDGE 40. The Braille EDGE 40 is 12.2 inches long by 4 inches wide by
0.86 inches high. Place the Braille EDGE 40 on a desk or table top with the
Braille display nearest you. Its shape resembles a long, thin rectangular
box. This section of the manual describes each side of the Braille EDGE 40
and the basic function(s) of each button. We will discuss the panels in the
following order: top panel, left panel, right panel, front panel, and rear panel.
1.4.1 Top panel
The top face of the unit contains the keyboard and Braille display. Along the
front edge of the top panel are 40 refreshable Braille cells. Just above the
Braille display. There are 40 small, oval-shaped buttons corresponding to
each of the 40 Braille cells. These buttons are called cursor routing keys.
When you are editing documents, you can use these keys to route your
cursor to the character of the corresponding Braille cell.

On each side of the Braille display are two capsule shaped keys. These are
the "UP" and "DOWN" scroll keys. The scroll keys are used to scroll the
Braille display through menus, fields, lists or text. You can use the scroll
keys to scroll by display length or line.
Above the Braille display are the Perkins keyboard and the function and
navigation keys. Near the center of the unit is a 9 key Perkins-style
keyboard, consisting of Braille dots 1:6, "SPACE", "BACKSPACE", and
"ENTER". When you are typing, you should place your fingers on these 9
keys in the following manner:
Place the index finger, middle finger, ring finger, and pinky finger of your left
hand on the left four buttons. Then, place the index finger, middle finger,
ring finger, and pinky finger of your right hand on the right four buttons.
Finally, place both of your thumbs on the spacebar.
The button where you placed your left index finger corresponds with dot
one in Braille. The button that your left middle finger is on corresponds to
dot two, and the button under your left ring finger corresponds to dot three.
The button on which your left pinky finger is placed is the Backspace key.
The button under your right index finger corresponds with dot four in Braille.
The button under your right middle finger is dot five, and the button on
which your ring finger is placed corresponds with dot six in Braille. The
button on which your right pinky is placed is the Enter key. And, the long
bar shaped button under your thumbs is the spacebar.
On the same row as the Space bar are 8 rectangular function keys: four to
the left of the spacebar, and four to the right. Moving from left to right, these
keys are numbered f1-f8 and are programmed with the following functions:
Esc, Tab, Ctrl, Alt, Shift, Insert, Windows, and Applications.
On each of the upper left and right corners of the top face of the Braille
EDGE 40 are 4 buttons in a circular pattern. These are the navigation
buttons and correspond to UP, DOWN, LEFT, and RIGHT arrows

respective to the direction the buttons are pointed. These keys are also
used in conjunction with other keys to create hot key commands.
Along the far edge of the top face of the unit, are located a speaker and 2
LED lights. The speaker is located between dot 1 and dot 4 and is used to
output system sounds and audio alerts.
The LED lights are located above the navigation buttons on the right side of
the top face. The left LED light shows Bluetooth status; when Bluetooth is
activated, this LED light turns blue. The right LED indicates the status of
the power; when you are charging the unit, the LED turns red. When the
Braille EDGE 40 is powered on, the LED turns yellow. These LED lights
help a sighted person easily determine the status of the unit when working
with students. This helps them quickly evaluate whether options need to be
changed for accomplishing current tasks, or if options are activated
unnecessarily, and can be turned off to save power, etc.
1.4.2 Left Panel
The left panel contains 2 items. About halfway between front and rear of the
unit is the Bluetooth on/off switch. Slide the switch toward the rear of the
unit to turn Bluetooth on. There is a Braille letter “b” behind the Bluetooth
switch to indicate the correct direction. Slide the switch toward the front of
the unit to turn Bluetooth off, in which case, you can save power while
using the internal applications on the unit or while the unit is used as a
Braille terminal via USB.
Near the rear of the unit on the left panel is the SD card slot. The Braille
EDGE 40 can accommodate high capacity SD cards up to 32GB.
1.4.3 Right Panel
The Right panel of the Braille EDGE 40 contains the USB OTG port and
the AC adapter jack. Nearer the front of the unit on the right panel is a small

port for connecting a USB cable. Use this cable to connect the Braille
EDGE 40 to a computer for use as a USB Braille display or to charge the
unit. To charge the unit via AC power, please connect the small round end
of the AC adapter cable to the round jack near the rear of the right panel.
Plug the larger, box-like end of the AC adapter in to a standard electrical
outlet.
1.4.4 Front Panel
The front panel contains only one button near the right end of the front
panel is a large, rectangular button used to turn the Braille EDGE 40 on/off.
Press the power button on the right side of the front panel for about 1
second to power the unit on/off.
When the unit is powered on, again, hold the Power button for about 1
second to power the unit off.
1.4.5 Rear Panel
The rear panel of the Braille EDGE 40 contains 2 very small buttons. Near
the right end of the rear panel is a small pin hole containing the “Hard
reset”button. The “Hard reset” button is used when the “Reset” button has
no affect or when the battery is completely depleted and connecting the AC
adapter doesn’t reboot the unit. You can use a toothpick or the end of a
paperclip to press the “Hard reset” button. Be careful when pressing the
“Hard reset” button as, if you are not careful, pressing too hard or using an
end too small may damage the device.
If you press the “Hard reset” button on the rear panel then press the power
button on the front panel, the Braille EDGE 40 reboots, initializing all the
settings on the unit to their factory defaults.

Toward the left end of the rear panel is a small, round recess with a dot-like
button inside it. This is the “Reset” button. If your unit is not responding
properly, press this button to perform a soft reboot of the Braille EDGE 40.
NOTE: do NOT press the "Reset" button for more than 5 seconds. It takes
about fifteen seconds for your unit to complete the reboot process.

2. Basic Functions
2.1 Power on/off
Press the power button on the right side of the front panel for about 1
second to power the unit on/off.
When the unit is powered on, again, hold the Power button for about 1
second to power the unit off.
2.2 How to navigate
Use the following keystrokes to navigate menus, lists, and programs on the
Braille EDGE 40:
1. Move to the next item in a menu or list:
Down navigation button or Space-4
2. Move to the previous item in a menu or list:
Up navigation button or Space-1
3. Move to the first item in a menu or list:

9. Cancel: Esc key or left navigation button

2.3 Function keys
On the same row as the spacebar there are 8 rectangular function keys, 4
to the left of the spacebar, and 4 to the right. These keys help you more
intuitively interface with your PC as they are mapped to common PC
keyboard functions. They can also be used to more easily perform
functions in the internal applications.
NOTE: The key mappings listed below reflect the functionality we feel to be
of most intuitive use for these keys. However, supported screen readers’
use of these function keys may vary, thus, you should consult each screen
reader’s documentation on use with the Braille EDGE to discover the
functions of these keys.
Also Note: some function keys also have Braille keyboard equivalents as
listed below.
From left to right, the function keys are as follows:
1. Esc: Cancels the current menu/program
Space-E (dots 1-5)
2. Tab: Advances the cursor to the next tab stop
Space -dots 4-5
3. Ctrl
4. Alt: Opens the menu
Space-M (dots 1-3-4)
5. Shift
6. Insert
7. Windows
8. Applications
Note: You cannot multi-task on the Braille EDGE 40, thus there is no hot
key for bringing up the main menu, as you must exit the current program
and return to the main menu before opening another application.
2.4 Using Menus
The main menu on the Braille EDGE 40 consists of the following 5 items:

1. Notepad
2. Terminal for Screen Reader
3. Applications
4. Options
5. Information
You can navigate the main menu, or any menu on the unit, using the
navigation commands listed in the previous section. You can also press the
menu's shortcut key, usually the first letter of the menu name, to quickly
jump to and execute that menu item. Often menu items can also be
executed instantly with a hotkey, enabling you to perform the desired action
without accessing the menus.
When viewing menu items, several things are displayed including the item
name, its shortcut key, a hot key if one is available, and whether the item
has a sub menu or opens a dialog.
1) Shortcut keys:
Shortcut keys are displayed in parentheses following the menu names for
example, Open (o). If you press the shortcut key, you can execute the
menu or item directly from anywhere in the menu.
2) Sub menus:
When a menu contains a sub menu, the word "Pulldown" is displayed after
the item to indicate that pressing "Enter" will "pull down" another menu.
3) Dialogs:
When the menu item opens a dialog, the word "Dialog" is displayed after
the item to indicate that pressing "Enter' on this item will bring up a dialog.
4) Hot keys:
Hotkeys generally consist of a modifier such as "Enter," "Space," or
"Backspace", pressed simultaneously with a letter or dot combination.
These are displayed following the shortcut keys.

For example, if you are in the Notepad, and press "Space-m (dots 1-3-4)"
or "F2," then press "Enter" on "File," you see "New (n) pull down Ctrl-n".
The word "New" is the menu option. YOU would press the letter "n (dots 1-
3-4-5)" to jump to "New" from within the "File" menu. Press "Ctrl-n" to
access the "New" document command from anywhere in Notepad. The “n”
is the shortcut key and "Ctrl-n" is the hotkey. It is important to note that
some hotkey commands are global, thus will work from anywhere on the
unit, and some are program specific.
Note: if you are in a sub menu or dialog box, and the Braille EDGE 40is
powered off, when the unit is powered back on, the sub menu or dialog is
closed and you are returned to the location at which you entered the menus.
2.5 Charging and using battery
Though the Braille EDGE 40 alerts you when the battery is low, it is
important to keep track of the battery status so as not to lose unsaved data
or unexpectedly disconnect a Bluetooth Braille display connection.
To check the battery power status, press "Space-P (dots 1-2-3-4)". The unit
displays the following 2 items:
1. Battery power level
2. Power source (battery, AC power or USB 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, the AC power or USB power supply.
To close the battery power status dialog, press F1 button (Esc).
When the battery level falls below 15%, the Braille EDGE displays the
message, “battery low”and suggests you connect the AC adapter. When
the battery level falls below 5%, the Braille EDGE displays a warning that
the unit will automatically hard reset in 3 minutes time if the AC adapter is
not connected.

Note: if you are concerned about losing Bluetooth connection settings, you
may wish to activate the “Auto disconnect Bluetooth at 10%” setting in the
“Global options”. If this item is set to “On”, the Braille EDGE 40 alerts you
and disconnects from a Bluetooth device when the battery level drops to
10%.
2.6 Reset and Hard reset
1. If the Braille EDGE 40 does not respond to keystrokes or commands, it
may be necessary to reset the unit. To perform a soft reset of the Braille
EDGE 40, press the “Reset” button on the rear panel. Do NOT hold the
“Reset” button for more than 5 seconds.
Note: it takes about 15 seconds for the unit to reboot.
2. If pressing the "Reset" button does not revive the Braille EDGE 40 or the
battery is completely depleted, you may need to perform a ‘Hard reset’. You
can use a toothpick or the end of a paperclip to press the ‘Hard reset’
button. Be careful when pressing the ‘Hard reset’button as pressing too
hard or using an end too small may damage the device. If you press the
“Hard reset” button on the rear panel then press the “power” button on the
front panel, Braille EDGE 40 reboots, initializing all settings to their factory
defaults.
2.7 Set date and time
It is important for use with the Schedule Manager and alarm functions, that
the date and time is set correctly. To set the date and time, follow the
instructions below:
1) From the Main menu, press “a (dot-1)” to open the Applications Menu.
Press “t (dots-2-3-4-5)” to open “Date and Time”. Press “Control-s (dots-2-
3-4)”, or press “alt” to open the Menu and press “enter” on “set”.

2) Type the time as hhmm using normal text editing commands. You may
also use the following navigation keys to modify the time.
Up/down button: change time
Left/right button: modify hour or minute
3) Press ‘Enter’ or right navigation button to move to the Date Edit box.
4) Type month, day and year as mmddyyyy. Ex) 01252012 (25th January,
2012) or you can modify the date using the following commands:
Up/down button: change value
Left/right button: modify month, day, year
5) Press ENTER to save your settings.
2.8 Using the help menu
You can access context specific help anywhere on the unit by pressing
“Space-h (dots-1-2-5)”. If you press the “Help” command, it brings up a list
of hot keys pertaining to the currently open program.
Move among the items using Space-dot 1/space-dot4. You can select an
item or function by pressing ‘Enter’. However, if you select a function which
cannot be performed in your current context, an alert sound is heard and
no action is executed.
2.9 Using a USB mouse with the Braille EDGE 40
You can use a USB mouse with the Braille EDGE 40 for additional
navigation options in Braille EDGE’s built in applications. To connect a
mouse to the Braille EDGE 40, follow below instructions:
