Rear Window Defogger (Option) The lines you see on the rear window warm the glass. Press the button to start warming your window. Audio Systems Your Delco' audio system has been designed to operate easily and give years of listening pleasure. But you will get the most enjoyment out your system if you acquaint yourself with it first. Find out what your Delco@system can do and how to operate all its controls, to be sure you're getting the most out of the advanced engineering that went into it. ... . .. FM Stereo FM stereo will give you the best sound. But FM signals will reach only about 10 to 40 miles (16 to 65 km). And, tall buildings or hills can interfere with FM signals, causing the sound to come and go. After 10 minutes it will go off by itself, or pressing the button again during the heating cycle will shut it off. If you need additional warming time, push the button again. AM The rangefor 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 pick up noise from things like storms and power lines. Try reducing the treble to reducethis noise. 1 NOTICE: Scraping the inside of your rear window could cut and damage the heater. Your warranty would not cover this damage.Don't put decals there, you might have to scrape them off. 129
