Emergency Operation (Trunked Mode)
Receiving An Emergency Call
If the radio receives an Emergency Channel
Assignment in trunked mode, an alert tone
sounds and the "EMG" status flag starts flashing.
Follow standard emergency procedures.
Sending An Emergency Call
1.
To enable an emergency transmission,
press and hold the EMERGENCY BUT-
TON (small red button near antenna) for
approximately one second. The radio
transmits an emergency message until
an Emergency Channel Assignment is
received. Upon receipt, the "EMG"
status flag turns on and the radio begins
operation on the selected group or the
home group, depending upon program-
ming.
2.
Press the PTT BUTTON and speak into
the microphone in a normal voice.
3.
Release the PTT BUTTON when the
transmission is complete and listen for a
reply.
Clearing An Emergency
If programmed for supervisory capabilities,
the M-PA can clear an emergency declared by it
or another radio. To clear an emergency on the
selected talk group, press "2nd", then "CLR" then
press the red EMERGENCY BUTTON near the
antenna. The M-PA will then send a clear emer-
gency message, lighting the "TX" flag. The "BSY"
status flag will come on briefly after the "EMG"
status flag goes out.
Dynamic Regrouping
Dynamic Regrouping is a feature which al-
lows the System Manager to dynamically program
new groups into selected radios. Upon develop-
ment of the regrouping plan, the site controller
sends each radio the regroup plan number, knob
setting(s), and activate/deactivate commands.
