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.
2.
PROBLEM
• No sound.
CHECK
• Are the MASTER VOLUME control and accompani­
ment volume levels turned up high enough?
3. 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.
4. 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)?
7. PROBLEM
• The sound is distorted or intermittent.
CHECK
• In this case, your batteries are probably flat and need
replacement.
