Maintenance and Service
The speaker enclosures may be cleaned using a soft cloth
to
remove fingerprints or
to
wipe
off
dust.
All
wiring connections
should be inspected and cleaned or remade at least once a
year.
If
a problem does occur, make sure
that
all connections are properly made, secure and clean.
If
a problem occurs in one
loudspeaker, rewire
that
speaker in a different location
within
the
system. Should the problem persist
then
the
problem
is
within
the speaker.
If
the speaker sounds fine in the
new
position it
is
a strong indication
of
a more in
depth
issue
with
the
electronics in
the
system. In the event
that
your speakers ever need service,
contact
your local Boston Acoustics dealer
or
visit www.bostonacoustics.com/dealers for a list
of
dealers in your
area.
