Emergency Operation
Sending an Emergency Alarm with Emergency Call
This feature allows you send an Emergency Alarm to
another radio. Upon acknowledgement, both radios can
communicate over a preprogrammed Emergency
channel.
If the radio has both emergency call and alarm features,
it automatically proceeds to the call mode after the
alarm is acknowledged.
1 Press the preprogrammed Emergency button to
activate the emergency call/alarm feature.
2 The display alternates EMERGENCY and the home
display.
3 A high-pitched tone sounds, indicating that the alarm
has been received by the trunked system’s central
controller.
A dispatcher acknowledgment (four high-pitched
tones) follows, accompanied by an ACK RECEIVED
display.
4 Hold the microphone vertically 1 to 2 inches (2.0 to 2.5
cm) from your mouth.
5 Press and hold the PTT button. Speak clearly into the
microphone.
6 Release the PTT to end the transmission.
7 Press and hold the preprogrammed Emergency button
until a tone sounds to exit Emergency mode.
