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. recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or
The data provided is believed 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 specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division.

WARNING:

Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.

q Confirmation of pick-up laser power Recording and reproduction can be checked by using the laser power meter. However, it should be used for checking only because there is variation in its measurement. When the measured value is excessively deviated from the reference value, replace the pick-up. Reference value (measured at room temperature of 25 °C) During reproduction (ppw) : 0.72 ± 0.1 mW During recording (vpw) : 5.5 ± 0.5 mW Note : Be very careful when using the laser power meter. The laser beam would cause damage to your eye if exposed to it directly.

q Lead-in switch position measurement mode Load a TDYS1 disc for reproduction (high reflecting disc). Note) Adjust the position of the lead-in switch to FF85 - FFD2. 1. Loosen 2 screws (A) fixing the mechanism switch P.C.B. 2. Retighten screws while pushing the mechanism switch P.C.B. in the arrow () direction and then measure the position of the lead-in switch again. After adjusting the position, tighten 2 screws (A) securely. (Fig.12)

Loosen 2 screws (A) Note) Apply thread lock to 2 screws on the P.C.B. after tightening them.

s TROUBLESHOOTING
When MD fails to operate When the objective lens of the optical pickup becomes dirty, MD may fail to operate. Clean the objective lens first and check MD for reproduction function. If it still fails to operate, check according to the following flow charts. Contaminant on the pickup lens such as dust and a foreign matter may cause the pickup to skip or the TOC (content of the selection) not to be displayed. Check if the lens is clean before making adjustments. If the lens is dirty, clean it as follows. q Turn off the power. Dampen the lens cleaning paper with a small amount of isopropyl alcohol and wipe the lens with it, using care not to cause any damage to the lens. Be sure not to touch the lens with your hand directly.
