Send an Emergency Call
An Emergency Call will send a type of dispatch giving your radio
priority access to channels.
The radio operates in the normal dispatch manner while in
Emergency Call, except, if enabled, it will return to one of the
following:
2 When you receive the
dispatcher’s
acknowledgment, you see
ACK RECEIVED, four tones
sound, the alarm ends, and
the radio exits the
emergency mode.
If no acknowledgement is
received, you see NO
ACKNOWLDG, the alarm ends,
and the radio exits the
emergency mode.
• Four tones
• Alarm ends
• Radio exits emergency
Note: For Emergency Alarm with Emergency Call: The radio
enters the Emergency Call state either after it receives the
dispatcher’s acknowledgment, or if you press the PTT button
while in Emergency Alarm. Go to step 2 below: “Send an
Emergency Call.”
Using this operation: means you will talk...
1. Tactical/Non-Revert on the channel you selected
before you entered the
emergency state.
2. Non-Tactical/Revert on a preprogrammed emergency
channel. The emergency alarm is
sent to this same channel.
