CHAPTER 10
Troubleshooting and Service Guide
Project Everest DD66000 loudspeakers are designed to provide years of
trouble-free service. No maintenance, aside from occasional battery
replacement, is required.
If a problem occurs, make sure that all connections are properly made and
clean. If a problem exists in one loudspeaker, reverse the speaker wires to the
left and right speakers. If the problem appears in the opposite speaker, the
cause is in another component or cable. If the problem remains in the same
speaker, then the fault is in the loudspeaker. In this event, consult your Project
Everest DD66000 dealer for assistance.
