7. Care and Maintenance
High technology material finishes are used in this product.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 speaker 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.
There are no user replaceable parts within the speaker and in the unfortunate event
of any malfunction, repair should be referred to either the supplying dealer or
consultant, the relevant importer, or ATC. ATC has every confidence in the quality
of each product that it manufactures.
