Troubleshooting

! Incorrect operation is often mistaken for trouble or malfunction. If you think that there is something wrong with this component, check the points
below. Sometimes the trouble may lie in another component. Inspect the other components and electrical appliances being used. If the trouble can-
not be rectified after checking the items below, ask your nearest Pioneer authorized service center or your dealer to carry out repair work.
! This unit may not operate properly due to static electricity or other external influences. In this case, proper operation may be restored by turn-
ing the power off, waiting 1 minute, then turning the power back on.
! Non-finalized (partial discs) CD-R/ -RW cannot be played on the CDJ-850.
! Irregularly shaped discs other than standard 12 cm discs cannot be played on the CDJ-850 (doing so will lead to damage or accidents).
! The BPM measured by the CDJ-850 may differ from the BPM indicated on the disc or that of a Pioneer DJ mixer, etc. This is due to the differ-
ent methods used for measuring the BPM, and is not a malfunction.
