Yamaha KMA-1080 User manual

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 any service required should be performed by an authorized YAMA-
HA 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 specifications 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 accumu-
lated 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 part replacement. Recheck all work before you apply power to the unit.

1. Critical Components Information
Components having special characteristics are marked Z
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohms shunt-
ed by 0.15µF.

WARNING: CHEMICAL CONTENT NOTICE!
This product contains chemicals known to the State of California to cause cancer, 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 ex-
pose 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.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both
polarities.
About Lead Free Solder
All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.
Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead solder, be
sure to use a soldering iron suitable to each solder.
“CAUTION”
“F401: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE
2.5A, 250V FUSE.”
“F402: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE
4A, 250V (KMA-1080) / 3.15A, 250V (KMA-980) FUSE.”
AV
WARNING: Lithium batteries
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
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 an ekvivalent typ som rekommenderas av
apparattillverkaren. Kassera använt batteri enligt fabri-
kantens instruktion.
VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittele-
maan tyyppiin. Hävitä käytetty peristo valmistajan ohje-
iden mukaisesti.
