OPTIONS, ATTACHMENTS 30.2.3 REMOTE CONTROL UNIT 1. Turn the radio power off. 2. Grasp the sides of the remote at the top serrated edges and pull upward. NOTE: When removed from its cradle, the remote is inoperable. Do not expose the remote or cradle to extreme heat, direct sunlight, solvents, or water. Use a slightly damp, soft cloth to clean the remote. Never immerse the remote in water. Keep the male telephone-type plug in the cradle clean. Use of a damp cotton swab is acceptable. 3. Reverse steps 1 and 2 to reinstall the remote control unit.

30.2.4 BATTERY REPLACEMENT Two AA-size alkaline batteries in the electronics module are required to maintain the unit’s memory when its main power is turned off. Battery replacement is required when the clock fails to keep time or the memory presets fail. NOTE: Turn off the radio’s power before replacing the batteries. 1. After removing the two screws that secure the access cover plate atop the module, remove the access cover plate. 2. Remove the two batteries. 3. Install two new 1.5 volt AA-size alkaline batteries. NOTE: Observe the proper polarity when installing the batteries. The correct battery polarity is illustrated on the battery holder. 4.

Replace the access cover plate and secure with the two screws. 30.2.5 PRECAUTIONS WHEN USING Retract the antenna when traveling in places with a low overhead clearance. For safety reasons, when operating, keep the radio volume at a level that permits hearing sounds outside the vehicle. Water can cause damage, if allowed in the speaker enclosures, radio, cassette player, or remote control unit. Keep water away from these parts. Do not wipe the knobs or buttons, or any other parts, with solvents such as benzene or thinner. Always use a soft, dry cloth (in extreme cases, alcohol may be applied sparingly to the cleaning cloth). WA450-3MC 5-15
