TRUNKED OR CONVENTIONAL MODE
OPERATION
SIREN/LIGHT OPERATION
Each siren/light key is designed to control an optional siren/light pack-
age. Pressing a siren/light key will light the key indicator. Each si-
ren/light key (except RESET) can be programmed for either CANCEL
or ADDITIVE operation. If programmed for CANCEL, then all other
siren/light activity is cancelled except for the activity associated with
this key. If programmed for ADDITIVE, then a key press will add its re-
spective siren/light activity to the current siren/light activity. It is impor-
tant to note that while the lights are additive, only a single siren can be
active at a time. The current siren will be determined from the recently
pressed key that contains a siren assignment.
Each siren/light key (except RESET) can be programmed for either Tog-
gle, Momentary or Timed. In Toggle, each key press will toggle the
state of the key between On and Off. In Momentary, a key’s respective
feature will only be active while the key is pressed and held. When pro-
grammed for Timed, the siren/light key activity will only be active dur-
ing the programmable time-out window. The duration of the time-out
window is programmable between from .5-127.5 seconds. During the
time-out window the respective key indicator will be on. When the timer
expires, the activity will be terminated and the indicator will turn off. If
an additional time-out key (programmed for ADDITIVE) is pressed dur-
ing the time-out window, then the time-out window is reset and both ac-
tivities will terminate at the same time.
AEGIS AND VOICE GUARD OPERATION
Voice Modes
Each system (trunked or conventional) in the radio is programmed for
either Aegis or Voice Guard communications. Aegis programmed sys-
tems have three (3) different voice modes: clear (analog), digital and pri-
vate. Voice Guard systems have two (2) voice modes: clear (analog) and
private. The voice modes are programmed on a per-group basis within
each trunked system and on a per-channel basis within each conven-
tional system. A radio must be equipped with the encrypt/decrypt option
before it will operate in Aegis or Voice Guard modes.
