Procedure:
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.
Turning the radio off also cancels the emergency state.
Sending a Silent Emergency Alarm
This feature allows you to send an Emergency Alarm to another
radio without any audio or visual indicator.
Upon acknowledgement, your radio’s microphone is
automatically activated, allowing you to communicate with the
other radio without pressing the PTT button.
This activated microphone state is also known as “hot mic”.
Note: If you press the PTT button during hot mic, and
continue to press it after the hot mic duration expires,
the radio continues to transmit until you release the
PTT button.
Procedure:
1 Press the preprogrammed Emergency button to activate
the silent alarm feature.
2 Press and hold the emergency button until a tone sounds to
exit the silent alarm mode.
If silent emergency alarm is used with emergency call, pressing
the PTT button exits the silent mode and initiates the
emergency call.
