AM-FM RADIO WITH CASSETTE PLAYER RADIO OPERATION To turn the radio on, turn the ignition key to the ACC or ON position. If you listen to the radio with the engine not running, turn the key to the ACC position. Radio reception is affected by station signal strength, distance from radio transmitter, buildings, bridges, mountains and other external influences. Intermittent changes in reception quality normally are caused by these external influences. Using a cellular phone in or near the vehicle may influence radio reception quality. ON⋅OFF/VOL control knob Turn the ignition key to the ACC or ON position, then push the ON⋅OFF/VOL control knob. If you listen to the radio with the engine not running, turn the key to the ACC position. The mode (radio or cassette) which was playing immediately before the system was turned off resumes playing. When no cassette is loaded, the radio comes on. Pushing the ON⋅OFF/VOL control knob again turns the system off. AHA1051 Heater, air conditioner and audio systems 4-11
