Caution:
1. When the batteries run down, replace them with a complete
set of six new batteries. NEVER mix old and new batteries.
2. Do not use different kinds of batteries at the same time.
3. In case electrolyte has leaked into the battery compartment,
wipe it off completely before installing new batteries.
4. To prevent possible damage due to battery leakage, remove
the batteries from the instrument if it is not to be used for an
extended period of time.

Maintenance
• Location
Avoid exposure to direct sunlight or other sources of heat.
Never leave it inside a car where it can get very hot. It may
cause discoloration or deformation. Vibration, excessive
dust, cold, low or high humidity can also cause malfunction.
• Handling
Avoid rough handling. Don’t drop or jolt the PSR-3(XJM as
this can damage the internal circuitry. Pressing too hard on
keys or controls may lead to malfunctions. When cords are
plugged into the rear panel jacks, pay particular attention not
to apply excessive force to them since this may damage the
terminals.
• Cleaning
Clean the exterior with a soft, dry cloth. Using chemical
solvents will damage the finish.
• Interference Through Electromagnetic Fields
Do not use your PSR-3(X)M close to television sets or other
equipment receiving electromagnetic signals as this could
cause interference noise in the other appliance.
• Service and Modifications
Your PSR-300M contains no user serviceable parts. Open­
ing it or tampering with it in any way can lead to electrical
shock as well as damage. Refer all servicing to qualified
YAMAHA personnel.
YAMAHA is NOT responsible for damage caused
by improper use.
