Cleaning of the external surfaves of the
unit
The exterior finish of your unit will last indefinitely
with proper care and cleaning.
Never use scouring pads, steel wool, scouring
powders or harsh chemical agents, alcohol, thinners,
benzene, insecticide or other volatile substances as
these will mar the finish of the equipment.
Likewise, never use cloths containing chemical
substances. If the unit gets dirty, wipe the external
surfaces with a soft, lint-free cloth.
Remedy

AC power outlet.

VOLUME control.

properly.
