The recommended cleaning method for your remote cassette tape player is the use of a scrubbing action, non-abrasive cleaning cassette with pads, which scrub the tape head as the hubs of the cleaner cassette turn. The recommended cleaning cassette is available through your dealer (GM Part No. 12344789). When cleaning the cassette tape player with the recommended non-abrasive cleaning casette, it is possible that the cassette may eject, because the cut tape detection feature on your tape player may recognize it as a broken tape. Use the following procedure to clean your remote cassette tape player. 1. Turn the radio on. 2. Insert the recommended cleaning cassette. 3. If the cleaning cassette ejects, insert the cassette at least three times to ensure thorough cleaning. 4. Eject the cleaning cassette if it does not eject on its own. After you clean the remote cassette tape player, press and hold the RECALL button on the radio until CLN appears on the radio display. While still pressing the RECALL button, press the EJECT button on the remote cassette tape player. Release both buttons when the radio displays ---, indicating that the CLN indicator has been reset. Fixed Mast Antenna The fixed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, you can straighten it out by hand. If the mast is badly bent, as it might be by vandals, you should replace it. Check every once in a while to be sure the mast is still tightened to the cowl. If tightening is required, tighten by hand, then with a wrench one quarter turn. 3-31
