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: 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

changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact 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 part replacement. Recheck all work before you apply power to the unit.

LITHIUM BATTERY HANDLINGThis product uses a lithium battery for memory back-up.

WARNING: Lithium batteries are dangerous because they can be exploded by improper handling. Observe the followingprecautions 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 disassemble the batteries.• Never heat batteries or throw them into fire.

6. VOL Circuit Board (Time required: about 25 minutes)



6-3 Remove the four (4) screws marked [160].

* When installing the VOL circuit board, slide the

volume knob up and down with the VOL circuit

board in contact with the VOL circuit board fixture

and check that it moves smoothly. Then secure the

circuit board with the screws. (Fig. 5)

12-4 White key

Insert a thin plate between the keyboards (in the

space pointed at by the triangle mark near the white

key fulcrum).

Push down the stopper marked [A] and move

forward the white key until the white keyboard hook

is released. The white key can then be removed byholding it up. (Figs. 10, 11)

* While doing the above step, take enough care not to

move the white key so far forward to damage the spring.

* The black key can be removed by removing the white

keys on both sides.

13-1 Hammer white key (black key)

Insert the hammer white key (black key) into the frame on

the back of the HED keyboard and attach the stopper

L88_W. Remove from the main unit. (Fig. 14)

13-2 Spring

With the HED keyboard on the top side, push down

the two ends of the spring in alignment with the cut

in the hammer white key (black key) and attach it to

the frame hook. (Fig. 15)

* Be careful of the direction of the spring. The spring

is shaped like “<”. Attach it so that its top looks like

“^”.

13-3 White key (black key)

With the white key (black key) caught in the area [B]

and key guide, check that the spring is securely

located in the spring receptacle inside the keyboard

fulcrum. Then slowly push in the top of [C] in thedownward direction and install. (Fig. 16)

Fit the seesaw dome (rubber contact) in the slit on

the back of the frame and attach the seven (7) screws

marked [260a]. The HE-D_SW circuit board L can

then be installed. (Fig. 9)
