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 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
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.
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!
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 official 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.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.

WARNING: THIS APPARATUS MUST BE EARTHED
IMPORTANT. The wires in this mains lead are coloured in accordance
with the following code:

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

BACKUP BATTERY
This device has a built-in backup battery. When you unplug the power cord from the AC outlet, the current scene data and
library data is retained. However, if the backup battery fully discharges, this data will be lost. When the backup battery is running
low, the LCD display indicates "Low Battery!" when you start up the system. (The Battery field indicates "LOW" or "NO" in the
Be sure to

USER LEVEL SETTINGS
User Level settings allow you to restrict the parameters that can be operated by each user, or to change the settings of user-defined keys and
preference settings for each user. Settings for each user can be stored as a "user authentication key" on a USB storage device, allowing users
to be switched easily, simply by connecting this storage device to a USB connector. This is convenient in the following situations.
· Unintended or mistaken operation can be prevented.
· The range of functionality operable by an outside engineer (guest engineer) can be limited.
· In situations in which multiple operators alternate with each other, output settings etc. can be locked to prevent unintended operations.
· Preferences of each operator can easily be switched.
User settings may be stored by users. To service the device, get the USB storage device storing the "user authentic key" from the user.

s DISASSEMBLY PROCEDURE
Precautions
Note: Take care not to trap your fingers.
* Install the filament tape and the harness clamp in the
same way as they were before removal.
* After replacing the FDMS2, FDMS4, FDMS8 and FDIN
circuit boards, be sure to calibrate the faders. (See
page 192.)
* MAC (Media Access Control) address is stored in the
CPUM circuit board assembly. If the CPUM circuit
board assembly is replaced, MAC address will be
changed.
* Notes on Flat Cable
Contacts are visible from the back. Pay attention not
to insert and install the cable to the connector
inversely. (Photo 1)
