ASTRO XTS 4250 Digital Portable Radio, Advanced Model 39
Common Radio Features
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
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).
