Cleaning The Unit
• To prevent fire or shock hazard, disconnect your unit from the AC power source when
cleaning.
• If the cabinet becomes dusty wipe it with a soft dry dust cloth. Do not use any wax or polish
sprays on the cabinet.
• If the cabinet becomes dirty or smudged with fingerprints it may be cleaned with a soft cloth
slightly dampened with a mild soap and water solution. Never use abrasive cloths or polishes
as these will mar the finish of your unit.
Caution:
Never allow any water or other liquids to get inside the unit while cleaning.
