USER’S GUIDE Triton Wireless Hand-held Terminal
Using the 35-key Keypad - cont’d.
Using the Alpha key on the 35-key Keypad
If the Triton hand-held computer is equipped with the numeric keypad, the unit will allow
alphabetic input in a mobile phone style interface.
Pressing the Alpha key once, will put the keyboard into Alpha Mode. Within Alpha Mode, a
numeric key (0 – 9 or period) can be pressed and released multiple times to allow input of
any of the three or four red symbols on the key. After no other key has been pressed for 200
milliseconds, the input will be processed.
For example, to type the letter ‘b’, the user would press the [Alpha] key ONCE, followed by
the [2] key TWICE. If the user does not press any other key for 200 milliseconds, the input will
be processed as a lower case letter ‘b’. If the user had pressed any key other than the [2]
key within the 200 milliseconds timeout, the system would have processed the ‘b’ and fol-
lowed it with the next key. If the user had pressed the [2] key a third time within the timeout
period, the input would have been processed as a lower case letter ‘c’.
To input a capital letter, the user must press the [Shift] key before the [Alpha] key, or directly
after the press of the [Alpha] key.
For example, to type the capital letter ‘B’, the user could press the [Shift] key ONCE, followed
by the [Alpha] key ONCE, followed by the [2] key TWICE, or, alternatively they could press
the [Alpha] key ONCE, followed by the [Shift] key ONCE, followed by the [2] key TWICE. The
system will respond to either input with a capital letter ‘B’.
