1.2 Front Edge
Along the front edge of the device (closest to you) is a slanted front panel with eleven controls.
The two outermost small round keys on each end are the System keys. They are referred to as S1
through S4, with S1 and S2 on the left and S3 and S4 on the right.
The S keys perform the following functions:
• S1: Main Menu
• S2: Menu of current application
• S3: Context Menu
• S4: Book Reader, open current book at last reading position
Moving inward are two large rectangular keys. These are referred to as BL and BR. In most cases,
they are both functionally equivalent to the Space key on the braille keyboard, meaning that
either of them can be used with a letter to execute a keyboard command that requires use of a
Space key. The only time this is not the case is when reading a book. While reading, BL and BR
function as alternative panning keys, allowing you, if you prefer it, to use your thumbs to move
forward or backward through a book.
In the center of the slanted front panel are five navigation keys. Starting from the left and going
clockwise they are N-Left, N-Up, N-Right, and N-Down, with N-Center in the middle. N-Up and N-
Down are used to move between items in a menu or a list. The four directional keys can be used
to move through a book.
At the bottom of the slanted front panel, at each end, is a hole for attaching a lanyard. The
matching holes are near the front corners of the left and right sides.
1.3 Left Side
On the left side of the device, from front to back, is the lanyard attachment point, followed by
the SD Card slot. There are braille letters, sd, above the SD Card slot.
