Premium standard features include data encryption standard (DES) single-bit cipher feedback (SBCF) analog encryption, high-output LCD, tri-color LED status indicator, 16-position rotary volume and channel knobs, programmable switch and function buttons, speaker switch, and indicator. Channels can be individually programmed for 25 kHz wideband or 12.5 kHz narrowband operation, analog or digital, plain or encrypted, with transmitter power settable from 25W to 110W in three steps (25W, 50W, and 110W). Up to seven shadow channels can be programmed for any channel providing all-mode radio performance. Sixteen encryption keys can be stored in the radio.
GUARDIAN P25 INTEROPERABLE RADIO FAMILY Guardian VHF Mobile 3Capacities 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.
