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.

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 starting up the system. (the Battery field also indicates "LOW"
or "NO" in the MISC SETUP screen.) In this case, immediately save the data to a USB memory.
Be sure to
perform it

) USB




USER LEVEL SETTINGS
User Level settings allow you to restrict the parameters that be operated by each user, or tochange the settings of the custom fader layer,
user-defined keys, and preference settings foreach user. Settings for each user can be stored as a "user authentication key" on USB
memory,allowing users to be switched easily, simply by connecting the memory 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.

DISASSEMBLY PROCEDURE
Precautions
* Install the filament tape and the harness clamp in the
same way as they were before removal.
* After replacing the FD and FD2 circuit boards, be sure
to calibrate the faders. (See page 183.)
* MAC (Media Access Control) address is stored in the
CPU circuit board. If the CPU circuit board 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.
