If an emergency broadcast is caught while receiving a UKW broadcast or playing back a cassette tape with the ignition switch in “ACC” or “ON” position, the display will show “ALARM” and the emergency broadcast will interrupt the current program. The volume level is set separately for listening to normal audio programs and for listening to emergency broadcasts. The volume level will therefore change automatically to that set when an emergency broadcast was last received. When the emergency broadcast is over, the radio will return to the previously received program and to the corresponding volume level.
