45-Key Pads
In order to provide the functionality of a full-size keyboard with only 45 keys, the
RFID ICODE handheld interface keypad makes use of modifier keys. Units
configured with the 45-key pad utilize five LED indicators (located above the
On/Off switch) to indicate the active state of the keypad modifier keys. Units
with the 45-key pad also have keypad functions to adjust contrast and backlight.

Modifier Keys
The following modifier keys (located on the bottom of a standard keypad) enable
you to access the various functions that can appear on a key. Modifier keys take
effect when first pressed and typically remain in effect until you press another key,
unless it is another modifier key (see the
Modifier Key Actions table on page 30 ).
Optionally equipped units can use LEDs to indicate the selection of a modifier
key. The
Power/Suspend Switch figure on page 23 provides examples of LEDs.

• CTRL and ALT Keys—operate in the same manner as on conventional
PCs, except that by default they have a one-time locking action to facilitate
one-handed operation.
