Something not working as it should? In many cases what ap-

pears to be a malfunction can be traced to a simple error that can

be remedied immediately. Before assuming that your PSR-500M

is faulty, please check the following points.

1. PROBLEM

• The PSR-500M speakers produce a "pop" sound whenever

the power is turned ON or OFF.

CHECK

* This is normal and is no cause for alarm.

2. PROBLEM

* No sound.

CHECK

* Is the MASTER VOLUME control turned up high enough?

* Is the power turned on? The Auto Power Off function auto-

matically turns off the power if no buttons or keys are

pressed for more than about 10 minutes when running the

PSR-500M from batteries.

* Are a pair of headphones plugged into the PHONES jack?

Have you accidentally plugged the foot pedal into the

phones jack?

3. PROBLEM

* Rhythm won't start or no rhythm sound.

CHECK

* Is the accompaniment volume turned up high enough?

* Is the ORCHESTRATION RHYTHM button turned on?

* Are you sure you pressed the START button?

* Perhaps the PSR-500M is in the SYNCHRO START mode,

so all you have to do is start playing.

4, PROBLEM

* Auto accompaniment won't function. No lower keyboard

sound.

* 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-500M

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 or internal circuitry.

Cleaning

Clean the exterior with a soft, dry cloth. Using chemical

solvents may damage the finish.

- Interference Through Electromagnetic Fields

CHECK

« Auto accompaniment won't sound right if the FINGERED

mode is selected and you're using SINGLE FINGER type

fingering or improper chord fingering.

* Are you sure you're playing in the left-hand section of the

keyboard when the FINGERED or SINGLE FINGER

mode is selected?

* Are all ORCHESTRATION buttons on?

5. PROBLEM

* Auto accompaniment chords don't seem to change prop-

erly.

CHECK

• Ате you playing chords that the PSR-500M can recognize

(see chord types on page 18)?

. PROBLEM

* Abnormal operation not listed above. Complete lack of

control.

CHECK

» The internal microprocessor may have been "locked up"

due to static electricity or other causes. Turn the instrument

OFF for a moment, then turn it ON again. If the lock-up

makes it impossible to turn the power off, remove the bat-

teries or unplug the AC adaptor. If you turn the power back

on within about 10 minute the previous contents of the

memory will be safely retained.

. PROBLEM

+ Sustain pedal operation is reversed (press-OFF, release-

ON).

CHECK

* You probably held the pedal pressed while turning the

power on or inserting the pedal plug into the FOOT

PEDAL jack. Turn the power off and then on again with

the pedal released.

Do not use your PSR-500M 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-500M contains no user serviceable parts.

Opening it or tampering with it in any way can lead to elec-

trical shock as well as damage. Refer all servicing to quali-

fied YAMAHA personnel.

YAMAHA is NOT responsible for damage caused

by improper use.
