3.5.1 Accessing Alpha Characters
On 36-key 7035s, all alpha characters are printed on the terminal plastic in orange
typeface above the numeric keys. To access an alpha character, you must first press
the <ORANGE> key and then press the numeric key above which the alpha
character you want to type is printed.
Important: Keep in mind that when you press the <ORANGE> key only once,
it is locked “on” by default. You need to press the <ORANGE> key
a second time to unlock or turn it off. Refer to “Key Lock Func-
tion” on page 52 for a complete description of this function.
Because the alpha keys on a 36-key keyboard are laid out much like the letters on a
telephone – generally in groups of three letters per numeric key – you need to take a
few extra steps to access the alphabetic characters. The examples below help
illustrate how to access alpha characters.
Choosing A Single Alpha Character
The examples below illustrate how to access A, B and C, all of which are printed in
orange characters above the numeric key, <1> (one).
To choose the letter ‘a’:
• Press the <ORANGE> key, and press numeric key <1>.
To choose the letter ‘b’:
• Press the <ORANGE> key, and press <1> twice.
To choose the letter ‘c’:
• Press the <ORANGE> key, and press <1> three times.
Note: Once you’ve typed an alpha character or characters, remember to turn
the <ORANGE> key off by pressing it a second time. This will end alpha
selection.
