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,

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

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 your body may have accumulated

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.

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

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: 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.

LITHIUM BATTERY HANDLING

This product uses a lithium battery for memory back-up.

WARNING :

Leave lithium battery replacement to qualiﬁ ed 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 ﬁ re.

ADVARSEL!

Lithiumbatteri-Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. levér det brugte batteri tilbage til leverandren.

VARNING

Explosionsfara vid felaktigt batteribyte. Använd samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren. Kassera använt batteri enligt fabrikantens instruktion.

VAROITUS

Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiiin. Hävitä käytetty paristo valmistajan ohjeiden mukaisesti. The following information complies with Dutch ofﬁ cial Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION OF BATTERIES.

• Please refer to the diassembly procedure for the removal of Back-up Battery.

• Leest u voor het verwijderen van de backup batterij deze beschrijving.

Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following precautions when

handling or replacing lithium batteries.

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.

• This applies only to products distributed by Yamaha Music U.K. Ltd. (3 wires)

WARNING

Components having special characteristics are marked and must be replaced with parts having speciﬁ cation equal to those originally installed.

13. LD1 Circuit Board, LD2 Circuit Board, LED Lens

* Installation position can be reversed and there is no

problem if the positions of the LD1 circuit board and the LD2 circuit board are opposite.

This document describes an example that the LD1

circuit board is installed over the LD2 circuit board.

13-1 Remove the sheet support. (See procedure 9.) 13-2 LD1 Circuit Board, LED Lens (ch 1 – ch 8)

(Time required: About 9 minutes)

13-2-1 Remove the three (3) screws marked [470]. The LD1

circuit board can then be removed. (Fig. 6)

13-2-2 Remove the LED lens (ch 1 – ch 8). (Photo 2) 13-3 LD2 Circuit Board, LED Lens (ch 9 – ch 16)

(Time required: About 12 minutes)

13-3-1 Remove the HAAD2 circuit board (ch 1 – ch 8).

(See procedure 11.)

13-3-2 Remove the three (3) screws marked [370]. The LD2

circuit board can then be removed. (Fig. 7)

13-3-3 Remove the LED lens (ch 9 – ch 16). (Photo 2)

* When installing the LD1 circuit board and LD2 circuit

board, install with the boss of the LED lens inserted into the hole of the circuit boards. (Photo 2)
