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.
÷ Static electricity and other external effects may cause this unit to malfunction. In this case, set the POWER switch to OFF, then
switch it on again after the disc has come to a complete stop.
÷ This unit cannot playback unfinalized (partial discs) CD-R or CD-RW discs.
÷ Irregularly shaped discs cannot be played on the CDJ-400 (as it may result in breakage or accidents). Please use only standard
circular 12 cm discs.
÷ The BPM value measured by the CDJ-400 may differ from the BPM value recorded on a CD or from our DJ mixer, but this
difference is a result of differences in the BPM value measurement method; not a result of a fault with the player.
÷ When playing CD-R/RW discs, the performance rate may drop due to quality of the recorded data.
