Top side
On the top there are elongated
buttons, which are assigned
numbers 7 and 8. This numbering
has nothing to do with Braille.
These buttons are used for
performing various actions, which
are described further in this manual.
If you take the device correctly, as
described earlier, then button #7 will
be located under the thumb of the
right hand and in some cases will
mean “yes” or “enter” and button #8
will be located under the thumb of
the left hand and will mean “no” or
“back”. Also, to the right of button #7
you can find the switch #9. Use
it to lock your keyboard against
accidental presses.
• In order to lock the keyboard,
slide switch #9 to the right.
• In order to unlock the keyboard,
slide switch #9 to the left.
