The
4344MkII
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 the cleaner's 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
4344MkII
loudspeaker system ever needs service, contact your local
JBL dealer.
