ASTRO Digital XTS 2500 Model III 53
Common Radio Features
Note: • For ALL Emergency signals: You can change channels
while in Emergency operation if the new channel is also
programmed for Emergency. The emergency alarm or call
continues on the new channel.
• If the new channel is NOT programmed for Emergency, an
invalid tone sounds 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
knob.
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).
