Emergency Operation
Silent Emergency Mode interactions

Silent Emergency and TMO/DMO Mode
As the Silent Emergency is only available in TMO, radio will
change the mode from DMO to TMO. When the user is in a
private or group call, Silent Emergency waits until any of the
calls is ended to change the mode and enter the Silent
Emergency Mode.
Power off in Silent Emergency mode
If user initiates the power off while in Silent Emergency mode
the radio goes to pseudo power off state. In this state audio
and visible indications are turned off but the radio is still on in
the Silent Emergency mode as before.
Power on in pseudo power off
User presses the Emergencey button, the radio indicates
power on but it is still in Silent Emergency mode.
Silent Emergency mode and PIN protect
The radio enters the Silent Emergency mode while in the PIN
protected state, it asks the user for the unlocking code. When
the radio exits the Silent Emergency mode, it is still in the PIN
protected state.
In Silent Emergency Mode when the battery is removed the
radio will turn on again in the normal mode.
If the Silent Emergency mode enters after the call the only
change on the display is the Private/Group notice which
disappears.
If the radio exits the Silent Emergency mode after powering off
in it, the radio shuts down without any indication.
