Maintenance and Service

The Century Gold loudspeaker systems have an oiled ﬁnish. Cleaning should be done with an untreated dust cloth. Do not use conventional furniture waxes and polishes, which are not designed for oiled ﬁnishes. If touch-up is necessary or the ﬁnish appears to be drying out, the surface may be re-oiled with a commercially available oil-ﬁnishing preparation. Do not use any solvents on the ﬁnish.

The grille may be gently vacuumed. Stains may be removed with an aerosol cleaner, following its instructions. Do not use any solvents on the grille.

All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum. The battery should be replaced approximately every three years. Consult your JBL dealer for speciﬁc recommendations.

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 system. If the problem remains in the same speaker, then the fault is with the loudspeaker. If the problem appears in the opposite speaker, the cause is in another component or cable. In the event that your Century Gold loudspeaker system ever needs service, contact your

local JBL dealer.
