CHAPTER 4: INSTALLATION, ADJUSTMENT, AND OPERATION
4.1 Radio Configuration
4.1.1 Channels
A channel consists of a receive and transmit frequency pair. The radio has a total of 256 selectable channels. Each
channel can be programmed for different receive and transmit frequencies, squelch, modulation, encryption, and
power. Each channel can have one of possible 16 keys assigned on a channel-by-channel basis. An 8-character
alphanumeric label identifies each channel or by its channel number if no text label. Up to 7 shadow channels can
be added to each channel. They enable the radio to be used in several squelch/encryption modes on each physical
channel.
4.1.2 Zones
A zone is a group of channels. Each zone can be assigned up to 16 channels. The radio can store up to 16 zones, or
groups of channels. The zones can be assigned names of up to 8 alphanumeric characters and assigned to banks
during programming. Three zones can be selected by the toggle switch, 16 zones by the front panel keyboard.
Channels are mapped to the channel select switch positions using the Guardian PC programmer. When a zone is
active (selected), channels within the zone are selected using the 16-position channel select switch on the front panel
of the radio.
4.1.3 Banks
A bank is a group of zones. Zones are assigned to banks during programming. The radio can store up to 4 banks of
16 zones each. Banks are assigned names of up to 8 characters.
