WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in per-
sonal injury, destruction of expensive components and failure of the product to per form 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, certifica-
tion, recognition 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, therefor, 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 buss in the unit (heavy gauge black wires connect to this
buss).
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 WelfareAgency (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 FORANY 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.
LUTHIUM 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 disassemble 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 leverandoren.
VARNING
Explosionsfara vid felaktigt batteribyte. Använd samma batterityp eller en ekvivalent typ som rekommenderas av
apparattillverkaren. Kassera använt batteri enlight fabrikantens instruktion.
VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiin.
Hävitä käytetty paristo valmistajan ohjeiden mukaisesti.
The following information complies with Dutch Official Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION
OF BATTERIES.

■ DISASSEMBLY PROCEDURE
1. Bottom Assembly (time required: about 1 min)
1-1 Remove the seven (7) screws marked [180]. The
bottom assembly can then be removed. (Fig. 1)
* If you turn the mixer upside down for
disaasembling and assembling, put 2 wooden
bolsters underneath the unit at its both side ends to
protect PN sheet from being damaged. (Fig. 1-1)
