SERVICE MANUAL

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 any service required should be performed by an authorized YAMAHA

Retailer or the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or

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

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 part replacement. Recheck all work before you apply power to the unit.

■ TO SERVICE PERSONNEL

1. Critical Components Information

Components having special characteristics are marked Z

and must be replaced with parts having specifications equal

to those originally installed.

2. Leakage Current Measurement (For 120V 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 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

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 WHATSOEVER!

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.

About Lead Free Solder /

The P.C.B.s installed in this unit are soldered using the fol-

lowing solder.

Among some types of lead free solder currently available, it

is recommended to use one of the following types for the

repair work.

• Sn + Ag + Cu (tin + silver + copper)

• Sn + Cu (tin + copper)

• Sn + Zn + Bi (tin + zinc + bismuth)

“CAUTION”

“F1, F2 : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A, 125V FUSE.”

CAUTION

F1, F2 : REPLACE WITH SAME TYPE 10A, 125V FUSE.

ATTENTION

F1, F2 : UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V.

Caution:

1. As the melting point temperature of the lead free solder is

about 30°C to 40°C (50°F to 70°F) higher than that of the

lead solder, be sure to use a soldering iron suitable to

each solder.

2. If lead solder must be used, be sure to remove lead-free

solder from each terminal section of the parts to be re-

placed and from the area around it completely before sol-

dering, or make sure that the lead free solder and lead

solder melt together fully.

■ IMPEDANCE SELECTOR

WARNING:

Do not change the setting of the IMPEDANCE SELECTOR

switch when the unit power is switched on, as doing so may

damage the unit.
