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.
IMPORTANT NOTICE
This manual has been provided for the use of authorized Yamaha Retailers and their service personnel. It has been assumed that basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and understood 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 personal
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, certification,
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 distributor's Service Division.
WARNING: Static discharges can destroy expensive components. Discharge any static electricity you 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.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those originally installed.

TO SERVICE PERSONNEL

Leakage Current Measurement (For 120 V Models Only). When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.
• Meter impedance should be equivalent to 1500 ohm shunted by 0.15µF.
• Leakage current must not exceed 0.5 mA.
• Be sure to test for leakage with the AC plug in both polarities.
• POLARIZATION (U, C models)
This product is equipped with a polarized alternating­current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER
THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
THIS PRODUCT SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED SERVICE PERSONNEL.
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs a laser. Therefore, be sure to carefully follow the instructions below when servicing.
1. Laser Diode Properties
•Materlal : GaAlAs
•Wavelength : 780 nm
•Emission Duration : Continuous
•Laser Output : max. 44.6µW*
*This output is the value measured at a distance of about 200 mm from the objective lens surface on the
Optical Pick-up Block.
2. When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens.

DISC FOR MD4S

MD4S
5
It's important that you buy the correct type of disc for use with your MD4S. For 4-track recording and playback, you must use MD DATA discs. Regular MiniDiscs can only be used for 2-track recording and playback (2 TR mode). MD DATA discs are used as a storage media for computers. The MD4S uses the MD DATA audio format to store data on them. Regular MiniDiscs are also referred to as MD discs, although they are used only for music.
New MD DATA discs do not require formatting before use with the MD4S. Discs that have been used to store computer data, however, must first be formatted. Regular MiniDisc decks cannot play MD DATA discs. Regular MiniDiscs recorded on the MD4S can be played on a regular MiniDisc deck. MiniDisc recordings made on a regular MiniDisc deck can be edited on the MD4S. MiniDiscs containing songs that were digitally copied from a commercial CD, however, cannot be edited due to the SCMS (Serial Copy Management System) protection system. Songs that were recorded in 8-track mode on a recorder such as the MD8 cannot be played back on the MD4S.
MD DATA
MiniDisc
Type Logo
MD DATA discs are for computer data storage applications. You can purchase them at computer stores. This is the type of disc you should buy for 4-track recording and playback with your MD4S. Note that there are two types available: playback only and rewritable. Buy the rewritable type. MiniDiscs are used only for music. Two types are available: playback only and recordable. The MD4S can record up to two tracks on the recordable type and play the playback only type.
