TROUBLESHOOTING

Incorrect operations can be mistaken as malfunctions. If you believe the unit is not operating correctly, consult the chart below.

Sometimes incorrect operation may be due to a malfunction in another component. If the problem is not fixed, check the other

components used with the player. If the problem still persists, contact your nearest Pioneer authorized service center or dealer for

service.
