WARNING: This product contains chemicals known to the State of California to cause cancer, 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 ser-
vice 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, de-
struction 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, recog-
nition 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.
IMPORTANT NOTICE FOR THE UNITED KINGDOM
Connecting the Plug and Cord
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 colored GREEN or 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.
WARNING
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.
Please keep the USB cap out of reach of children, to keep them from accidentally swallowing it.
This mark indicates a dangerous electrically live terminal. When connecting an external wire to
this terminal, it is necessary either to have “a person who have received appropriate guidance on
handling” make the connection or to use leads or a cord that have been manufactured in such a
way that the connection can be made simply and without problem.
印の部品は、安全を維持するために重要な部品です。交換する場合は、安全のために必ず指定の部品をご使用ください。
USBキャップは、子供が誤って飲み込まないように、子供の手の届かないところに保管してください。
マークは、危険活電部であることを示します。この端子への外部からの配線接続は、適正な取扱指導を
受けた者が行なうか、問題なく容易に接続できるように製作されたリ−ド線、またはコードを使用する
必要があります。

DISASSEMBLY PROCEDURE(分解手順)
1. Top Panel (Time required: About 2 minutes)
1-1 Remove the nine (9) screws marked [1120]. The top panel
can then be removed. (Fig. 1)
* When installing the top panel, first tighten the priority
screws as shown in Fig. 1.
Caution:
• Install the binding tie and the cord clamp in the same way
as they were before removal.
• Pay attention not to insert and install the FFC cable to the
connector inversely. (Photo A)
