136 UNDERSTANDING YOUR INSTRUMENT PANEL Electrical Disturbances Radio waves may pick up electrical disturbances during transmission. They mainly affect the wave amplitude, and thus remain a part of the AM reception. They interfere very little with the frequency variations that carry the FM signal. AM Reception AM sound is based on wave amplitude, so AM reception can be disrupted by such things as lightning, power lines and neon signs. FM Reception Because FM transmission is based on frequency variations, interference that consists of amplitude variations can be filtered out, leaving the reception relatively clear, which is the major feature of FM radio. SALES CODE RBK-AM/ FM STEREO RADIO WITH CD PLAYER AND CD CHANGER CONTROLS Radio Operation Power/Volume Control Press the ON/VOL control to turn the radio on. Turn the volume control clockwise to increase the volume.
