Chapter 1 — Using the CN4
CN4 Series Mobile Computer User’s Manual 15
The large numeric keypads are for applications that require mainly
numeric data. These keypads also lets you enter special characters,
including the alphabet, by pressing color-coded key sequences. The
CN4e provides larger input keys better suited for blind entry or glove
usage.
Using the Color-Coded Keys
Each keypad available for the CN4 provides color-coded keys to let
you access additional characters, symbols, and functions printed on
the keypad overlay. Once you understand how to use the color-coded
keys and key sequences, you can access all of the additional features
printed on the keypad overlay. There are two color-coded modifier
keys on the numeric keypad: the orange B key and the green C key.
The alphanumeric keypads have only the orange B color-coded
modifier key.
Capitalizing Characters
To capitalize a single character on alphanumeric keypads, press the
shift key, and then the character. To type all alphanumeric characters
as uppercase letters, you can enable the Caps Lock feature on the CN4
keypad.
