It has been assumed that basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and under- stood by the users, and have therefore not been restated. WARNING :Failure to follow appropriate service and safety procedures when servicing this product may result in per- sonal injury, destruction of expensive components and failure of the product to perform as specified. For these reasons, we advise all Yamaha product owners that all service required should be performed by an authorized Yamaha Retailer or the appointed service representative. IMPORTANT :This presentation or sale of this manual to any individual or firm does not constitute authorization certifi- cation, recognition of any applicable technical capabilities, or establish a principal-agent relationship of any form. The data provided is belived to be accurate and applicable to the unit(s) indicated on the cover. The research engineering, and service departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable and changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributors Service Division. WARNING :Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to this bus.) IMPORTANT :Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (Where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHAT SO EVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. WARNING Components having special characteristics are marked and must be replaced with parts having specification equal to those originally installed. RadioFans.CN 收音机爱 好者资料库 WARNING: LASER SAFETY This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precaution must be used during servicing of the unit. 1) When testing and / or repairing any component within the product, keep your eyes and skin more than 30cm away from the laser pick-up unit at all time. Do not stare the laser beam at any time. 2) Do not attempt readjustment,disassemble and repair of the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION - Use of controls or readjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. PROTECTION OF EYES FROM LASER BEAM DURING SERVICING Laser Diode Properties * Material : GaAlAs * Wavelength : 783789 nm * Emission Duration : Continuous * Laser Output Power : Less than 44.6 W Laser output is measured at a distance of 20cm from the object lens on the optical pick-up head. (Note) When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens. This label is located on the interior. Varningsanvisning fr laserstrlning.

Input a 1 kHz, 0 dB signal into ANALOG IN L and R and check that the output level at PHONES OUT, L and R is +3 dBm 2 dB. Also, vary the input level of ANALOG IN L and R so as to obtain the +8 dBm 1 dB (100W output power) at PHONES OUT L and R and check that the distortion factor is less than 5%. 9. Digital Input Level Select COAXIAL from the INPUT SELECT switch and press the REC key (REC stand-by state). Input a 1 kHz, full-scale signal into COAXIAL IN and check that +18.5 dBm 1 dB signal is output from ANALOG OUT L and R. Also, input a 1 kHz, full-scale signal into AES/EBS IN and check that a +18.5 dBm 1 dB signal is output from ANALOG OUT L and R. 10. Recording check Select ANALOG from the INPUT SELECT switch. Press the AUTO button, and then press the REC button (AUTO REC START mode). Input 1 kHz, 0 dBm signals into the ANALOG IN L and R to record them on the CD-RW disk. Playback the recorded signals to check that the recording has been made properly.
