Function Key

Descriptions

The terminal’s operating mode and context determine the specific action

performed when you press one of the following function keys. The following

descriptions are provided solely to acquaint you with some general characteristics

of these function keys before presenting more detailed system mode procedure

descriptions.

Cancel Key

Pressing the cancel key in normal mode—when the terminal’s application is

loaded and running—usually has the same effect as pressing the Esc (escape)

key on a PC. That is, it terminates the current function or operation.

In system mode, use cancel to perform a variety of functions. The most common

use of cancel in system mode is to exit a system mode submenu and return to the

main system mode menu. The specific effect of pressing the cancel key depends

on the currently active system mode menu.

Backspace Key

In normal mode, the backspace key is commonly used to delete a number, letter,

or symbol on the terminal’s display screen. Press backspace one time to delete

the last character typed on a line. To delete additional characters, moving from

right to left, press backspace once for each character or hold down backspace to

delete all characters on a line.

In system mode, the specific effect of pressing backspace depends on the

currently active system mode menu.

ALPHA Key

In normal mode, the ALPHA key enables you to enter one of the two or more

characters or symbols assigned to individual keys on the 12-key Telco-style

keypad. Use the ALPHA to enter up to 50 different ASCII characters through the

following procedure:

1 Press the key on the 12-key keypad that shows the letter or symbol you want

(for example, use 2 to type 2, A, B, or C). The number (1–9 or 0) or the symbol

(* or #) you pressed now displays.

2 Press ALPHA once to display the first letter. Continuing our example, 2

ALPHA displays the letter A.

3 Continue pressing ALPHA as many times as required to display the desired

character. For example, press 2 to display the number 2; press ALPHA once

to display the letter A, twice to display B, or three times to display C. If you

press ALPHA one more time, you cycle back to the number 2.

NOTE

If you firmly press and hold down one of the keys on the 12-key keypad without

using ALPHA, the same character repeats until you stop pressing the key. For

example, if you press 2 and hold it down, “2222222...” displays
