Something not working as it should? In many cases what

appears to be a malfunction can be traced to a simple error that
can be remedied immediately. Before assuming that your
PSR-300M is faulty, please check the following points.

1. PROBLEM

■ The PSR-300M speakers produce a “pop” sound when

ever the power is turned ON or OFF.

CHECK
• This is normal and is no cause for alarm.

PROBLEM

• No sound.

CHECK
• Are the MASTER VOLUME control and accompani

ment volume levels turned up high enough?

PROBLEM

• Rhythm won’t start or no rhythm sound.

CHECK
• Is the accompaniment volume turned up high enough?
• Are you sure you pressed the START button?
• Perhaps the PSR-300M is in the SYNCHRO START

mode, so all you have to do is start playing.

PROBLEM

• Auto accompaniment won’t function. No lower key

board sound.

CHECK
• Auto accompaniment won’t function 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 FIN
GER mode is selected?

• The left-hand section of the keyboard will produce no

sound if synchro start is disengaged in the FINGERED
or SINGLE FINGER mode.

5. PROBLEM

• The accompaniment key changes while you’re playing.

CHECK
• Perhaps you accidentally pressed a key in the left-hand

range.

6. PROBLEM

• Auto accompaniment chords don’t seem to change prop

erly.

CHECK
• Arc you playing chords that the PSR-300M can recog

nize (see fingering chart on page 19)?

PROBLEM

• The sound is distorted or intermittent.

CHECK
• In this case, your batteries are probably flat and need

replacement.
