Troubleshooting
If you suspect a malfunction, perform the following checks,
since a simple operating error may be the cause of the problem.
The problem may also be caused by factors other than the
headphones themselves, so be sure to check the sound
components with which the headphones are used.
Perform the following checks, and if the problem persists,
consult your dealer or nearest Pioneer service station.
