Comfort Controls & Audio Systems Gain Control Some models have this control below the audio system. To get more bass sound, move the GAIN control to adjust the amount of bass. Understanding Radio Reception F M Stereo FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the soundto come and go. AM Stereo Your Delco@ system may be able to receive C-Quam@ stereo broadcasts. Many AM stations around the country use C-Quam@ to produce stereo, though some do not. C-Quam@ isa registered trademark of Motorola, Inc. If your Delco@ system can get C-Quam@ signals, your stereo indicator light will come on whenyou are receiving it. AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can also pick up noise from things like storms and power lines. To lower this noise, try reducing the treble level. ' 140
