Capacities
Channels
There are 256 channels (frequency pairs) available for programming. Each can
be set for receive and transmit frequencies, wideband or narrowband, analog or
digital, various squelch types, encryption key, power output level, and an 8-
character alphanumeric channel tag (name).
Zones of Channels
Sixteen zones (groups of channels) are available for programming. Each zone
can have up to 16 channels (16 zones x 16 channels/zone=256 channels).
Zones are assigned group tags (names) of up to 8 alphanumeric characters, and
selected as programmed by the toggle switch, function buttons, or through the
menu and keypad.
Banks of Zones
Four banks (groups of zones) are available for programming. Each bank can
have up to 16 zones assigned. Banks are assigned group tags of up to
8 alphanumeric characters, and selected using the menu and keypad.
Shadow Channels
Up to 7 shadow channels are available for each primary channel. Shadow
channels enable you to monitor and reply (if all settings match) to all
transmissions on a given channel. Shadow channels can have different
modulation modes (analog or digital), bandwidths, squelch modes, digital
network access codes (NAC), and encryption key than their associated primary
channel. Each shadow channel must have the same transmit and receive
frequencies, scan list, talk-around, locked options, and transmit power level as
its associated primary channel. The primary or shadow channel can have
analog encryption enabled. Shadow channels count toward the 256-channel
total radio capacity. Shadow channels are created and edited through the
programming software. Consult authorized personnel for assigning a shadow
channel.
Encryption Keys
Up to 16 encryption keys can be stored in the radio for selective assignment to
each applicable channel. Selection of a new key from the key list replaces the
default key for a selected channel.
