Common Radio Features

The silent emergency state continues until you:

Press and hold the

Emergency button for about a second to exit the

emergency state.

Press and release the PTT button to exit silent

emergency and enter regular dispatch or emergency call.

Note:

For ALL Emergency signals, when changing channels:

• If the new channel is also programmed for Emergency, you can

change channels while in Emergency operation. The

emergency alarm or call continues on the new channel.

• If the new channel is NOT programmed for Emergency, you

see NO EMERGENCY, and hear an invalid tone until you exit

the Emergency state or change to a channel programmed for

emergency.

Emergency Keep-Alive

If the radio is in the Emergency state, with Emergency Keep-Alive

enabled, you cannot turn off the radio by using the On/Off Control

button.

With Keep-Alive, the radio will only exit the Emergency state using

one of the ways mentioned in the previous sections (Emergency

Alarm, Silent Emergency Alarm, or Emergency Call).
