When using a scrubbing action, non-abrasive cleaning cassette, it is normal for the cassette to eject because your unit is equipped with a cut tape detection feature and a cleaning cassette may appear as a broken tape. To prevent the cleaning cassette from being ejected, use the following steps. 1. Turn the ignition to ON or ACCESSORY. 2. Turn the radio off. 3. Press and hold the SOURCE button for two seconds. The tape symbol on the display will flash three times. 4. Turn the radio on and insert the scrubbing action cleaning cassette. 5. Eject the cleaning cassette after the manufacturer's recommended cleaning time. When the cleaning cassette has been ejected, the cut tape detection feature is active again. You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassette will not eject on its own. A non-scrubbing action cleaner may not clean as thoroughly as the scrubbing type cleaner. The use of a non-scrubbing action, dry-type cleaning cassette is not recommended. If your vehicle is equipped with the AM-FM Stereo with Cassette Tape Player, press and hold the eject button for five seconds to reset the CLN indicator after you clean the player. The radio will display --- to show the indicator was reset. If your vehicle is equipped with any other radio, press and hold the eject button for three seconds to reset the CLEAN TAPE indicator after you clean the player. The radio will display CLEAN TAPE MSG CLEARED to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before you have your tape player serviced. 3-47
