CD-C831W SAFETY PRECAUTION FOR SERVICE MANUAL WARNINGS THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO THE LASER BEAM. 1-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED ON WITDOUT A COMPACT DISC IN POSITION AND THE PICK-UP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT LOOK INTO THE PICK-UP LENS. 2-THE LASER POWER OUTPUT OF THE PICK-UP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY PRE-SET BEFORE SHIPMENT. DO NOT ATTEMPT TO RE-ADJUST THE LASER PICK-UP UNIT DURING REPLACEMENT OR SERVICING. 3-UNDER NO CIRCUMSTANCES STARE INTO THE PICK-UP LENS AT ANY TIME. 4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. CAUTION Laser Diode Properties Material: GaAIAs Wavelength: 780 nm Emission Duration: continuous Laser Output: max. 0.6 mW This Mini Component System is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear cover. Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. As the laser beam used in this compact disc player is harmful to the eyes, do not attempt to disassemble the cabinet. Refer servicing to qualified personnel only.

Whilst pressing down the button and the button, hold down the ON/STAND-BY button for at least 1 second. Press the ON/STAND-BY button to enter the stand-by mode. Caution: The operation explained above will erase all data stored in memory including clock and timer settings, and tuner and CD presets. 1 2 Reset the microcomputer under the following conditions: To erase all of the stored memory contents (clock and timer settings, and tuner and CD presets). If the display is not correct. If the operation is not correct. Caution: The operation explained above will erase all data stored in memory including clock and timer settings, and tuner and CD presets. 3 1 2 To change the tuning zone: Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to AM tuning interval (span) of your area. The International Telecommunication Union (ITU) has established that member countries should maintain either a 10 kHz or a 9 kHz interval between broadcasting frequencies of any AM station. The illustration shows the 9 kHz interval zones (regions 1 and 3), and the 10 kHz interval zone (region 2). AM/FM interval (span) Notes concerning use: Replace the batteries if the operating distance is reduced or if the operation becomes erratic. Periodically clean the transmitter LED on the remote control and the sensor on the main unit with a soft cloth. Exposing the sensor on the main unit to strong light may interfere with operation. Change the lighting or the direction of the unit. Keep the remote control away from moisture, excessive heat, shock, and vibrations. CD-C831W OPERATION MANUAL CD-C831W DISASSEMBLY Caution on Disassembly Follow the below-mentioned notes when disassembling the unit and reassembling it, to keep it safe and ensure excellent performance: 1. Take cassette tape and compact disc out of the unit. 2. Be sure to remove the power supply plug from the wall outlet before starting to disassemble the unit. 3. Take off nylon bands or wire holders where they need to be removed when disassembling the unit. After servicing the unit, be sure to rearrange the leads where they were before disassembling. 4. Take sufficient care on static electricity of integrated circuits and other circuits when servicing. CD-C831W STEP REMOVAL PROCEDURE FIGURE 1 Top Cabinet 1. Screw .....................

Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type • Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken,check the following items. Remove the cabinet and follow the troubleshooting instructions. "Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below." Turn the power off. Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol. Do not touch the lens with the bare hand. Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use a cleaning disc designed for CD optical pickup lenses. HOW TO USE 1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush on the CD cleaner disc which has the mark next to it. 2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then press the play button. 3. You will hear music for about 20 seconds and the CD player will automatically stop. If it continues to turn, press the stop button. CAUTION The CD lens cleaner should be effective for 30 - 50 operations, however if the brushes become worn out earlier then please replace the cleaner disc. If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth. Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and / or rinse with clean water and seek medical advice. The CD cleaner disc must not be used on car CD player or on computer CD ROM drives.
