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.
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 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 leverandøren.
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 tyyppiin.
