Using 8000 Mobile Computer
This alphanumeric keypad is set to numeric mode by default. The [FN/ALPHA] key serves
as a toggle among numeric, alpha (lower-case alphabetic), ALPHA (upper-case alphabetic)
input modes, as well as function mode.
Note: It is not necessary to hold down the [FN/ALPHA] key.
The associated icon will appear on the lower-right corner of the screen in a sequence as
shown below.
Screen Icon
FN/ALPHA Key Input Mode
(none) N/A Numbers
A Press [FN/ALPHA] one time Upper-case alphabetic
a Press [FN/ALPHA] two times Lower-case alphabetic
F Press [FN/ALPHA] three times
Function Mode
When in alpha mode, it takes turns to show alphabets and number when you keep
pressing the same key; each press must not exceed one second. For example, keep
pressing the number key [2], it will take turns to show “A”, “B”, “C” or “2” for upper-case,
and “a”, “b”, “c” or “2” for lower-case.
When you first press the number key [2], it will produce the letter “A” or “a”.
When you press the number key [2] twice (the time interval must not exceed one
second), it will produce the letter “B” or “b”.
When you press the number key [2] three times (the time interval between each
press must not exceed one second), it will produce the letter “C” or “c”.
When you press the number key [2] four times (the time interval between each press
must not exceed one second), it will produce the number “2”.
In order to get the desired character, you will need to press the same key, one to four
times (the time interval between each press must not exceed one second). Only when
you stop pressing the same key for longer than one second or you press another key, will
the system send the real key code to the application program.
When in function mode, the [FN/ALPHA] key works with a number key. Press the
[FN/ALPHA] key three times, and its associated icon F
will be displayed on the screen.
Press the second key, say [5], to complete the key combination and access the function
[F5]. Press [FN/ALPHA] again and the icon F
will go off.
Below briefly describes the functions of common keys on the mobile computer.
