1.6 Care and Maintenance
High technology material finishes are used in these products. The surfaces are
durable and with a little care can be kept as good as new even under conditions of
heavy use. Normally a dry duster will be all that is required to keep the finishes
clean. Heavy soiling can be cleaned using a cloth slightly moistened with a non-
abrasive household cleaner.
There are no components within the speakers that can be considered expendable,
or that would benefit from regular maintenance.There is no requirement for any
kind of routine service work and there is no schedule for preventative maintenance.
Should a speaker fail to switch on when the power switch is operated the fuse
should be inspected. Lift out the fuseholder cover using a small flat-blade
screwdriver,remove the fuse and inspect it for damage.If required,a spare fuse may
be supplied in the body of the fuseholder cover. Fuses most often fail only because
of a serious electrical fault.If this is the case then simply replacing the fuse will only
result in another fuse failure.The speaker should be returned to ATC for service if
a second fuse fails.
There are no user replaceable parts within the speakers and in the unfortunate
event of any malfunction,repair should be referred to either the supplying dealer or
consultant,the relevant importer,or ATC.
