priority system and if found, locks onto it. This improves
network efficiency by preventing unnecessary multisited
calls.
Emergency (Optional)
An "Emergency" message is initiated by the caller and
automatically transmitted by the radio on the control
channel. The system automatically assigns the highest
priority to the talk group.
Wide Area Scan (Optional)
When the radio unit loses the control channel of the
current system, the radio automatically begins searching for
a new control channel. The intelligent search algorithm uses
a preprogrammed map of adjacent systems to ensure
minimum transition time.
Dynamic Regrouping (Optional)
The unit is capable of being reprogrammed over the air
while the radio is still active. Multiple talk groups can be
added to a radio unit or optionally, the radio can be forced
to communicate on designated talk groups.
GE-MARC (ONLY) FEATURES
