CHAPTER 10
Troubleshooting and Service Guide
Project K2 S9900 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 K2 S9900 dealer for
assistance.
