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.
