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.
