Sending a Silent Emergency Alarm

When and where to use:This feature allows you to send an Emergency Alarm to the system without
triggering any audio or visual indicators.
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.
The display shows no changes, the LED does not light up, and you hear no tones. The silent
emergency state continues until you perform the next step.
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.

Impact Detection

This feature activates Emergency mode when the radio detects a force of gravity impact or orientation
changes on the vehicle in the event of a vehicle crash or rollover. The radio automatically activates
Impact Detected condition when the impact event meets or exceeds a predefined threshold.
The radio must stay in this condition for a preprogrammed amount of time before the Emergency Alarm
or Call is activated. This feature also sends out the location-based information if the GPS feature is
enabled.
In the event of hardware failure or malfunction, the radio alternatively displays Impact HW and Error
and a tone sounds when the radio power-up. Any button press of the radio or accessory except the
programmed button for volume and backlighting functionality ceases the error message and sound.
The following scenarios affect the Emergency feature activation:
• Pressing a preprogrammed Emergency button cancels the Impact Detection sequence and enters
the Emergency mode.
• Pressing the PTT button does not suspend the Impact Detection sequence.
• Pressing the PTT button, the Clr menu button, or the preprogrammed Clear button when the radio
displays the Impact Detected display alert, exits the Impact Detected condition.
