On the face, the Space Bar flanked by Shift and Alt are closest to you. The Space is the widest key. To
its left is Shift, and to the right of Space is Alt. The Shift and Alt also serve as dots 7 and 8 when typing
with 8-dot braille.
Braille Cells
Just behind the Space Bar, moving toward the back, is a line of 18 braille cells. Each braille cell is an 8-
dot cell. Above each cell is a cursor routing bar. As you use the device, braille appears on these cells.
You may use the cursor routing keys to click on buttons or to move the cursor to the position of the
routing button in an editing environment.
Key Lock
The Key Lock slide switch is left of the braille cells. Slide it toward the back of the device to lock the
keys. Slide it to the front to unlock them.
LEDS for Charge and Power
To the right of the braille cells, there are two light-emitting diodes (LEDs). There is a green LED for
power, and a red LED for charging status.
Braille Input Keys
Above the cursor routing keys, toward the back of the device, the six traditional braille input keys are
arranged in an ergonomic configuration. Use these keys to type text or hold down the Space Bar with
dot combinations to perform special functions. In 8-dot braille, use the thumbs to press dot 7 (the Shift
key) or dot 8 (the Alt key).
Microphone and Speaker
The microphones are located on the left and right side of the face.
The speaker, which can be used for phone calls, is located on the right side of the face.
While the unit is designed to use Bluetooth headsets or as a speakerphone when making or receiving
phone calls, it is also possible, although a bit clumsy, to hold the device to your ear like a phone.
Cursor Pad and Select
Just above the braille input keys, between dots 1 and 4, there is the cursor pad with four arrow keys and
a Select key in the middle. Press the arrows to move through documents or menus, and press Select to
make a choice.
Menu and Home
To the left and right of the arrow keys are two long vertical bars. The bar on the left side is the Menu
key, and the bar on the right is the Home key. The Menu key opens a menu for the app you are currently
running. The Home key takes you back to the Home screen. Hold Home to retrieve a list of recently
used apps.
