The enclosure may be cleaned using a soft cloth to remove
fingerprints or to wipe off dust.
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.
If a problem occurs, make sure that all connections are properly
made and clean. If a problem exists in one loudspeaker, reverse the
connection wires to the left and right system. If the problem remains
in the same speaker, then the fault is with the loud-speaker. If the
problem appears in the opposite speaker, the cause is in another
component or cable. In the event that your subwoofer ever needs
service, contact your local JBL dealer or distributor or www.jbl.com
for a service center near you.
