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 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 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 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: THIS APPARATUS MUST BE EARTHED
IMPORTANT
THE WIRES IN THIS MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
GREEN-AND-YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
The wire which is coloured GREEN and YELLOW must be connected to the terminal in the plug which is marked by the letter
E or by the safety earth symbol or coloured GREEN and YELLOW.
The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED.
* This applies only to products distributed by YAMAHA KEMBLE MUSIC (U.K.) LTD.
s WARNING
Components having special characteristics are marked Z and must be replaced with parts having specification equal to
those originally installed.

LITHIUM BATTERY HANDLING
This product uses a lithium battery for memory back-up.
WARNING : Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following
precautions when handling or replacing lithium batteries.
· Leave lithium battery replacement to qualified service personnel.
· Always replace with batteries of the same type.
· When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.
· Never solder directly to the cells. Perform the soldering as quickly as possible.
· Never reverse the battery polarities when installing.
· Do not short the batteries.
· Do not attempt to recharge these batteries.
· Do not disasemble the batteries.
· Never heat batteries or throw them into fire.
ADVARSEL!
