•
Remove dust and loose dirt with a clean, soft cloth.
•
Remove grease, fungus, and ground-in dirt from the case using a cloth
dampened with trichlorethane.
CAUTION: TRICLORETHANE fumes are toxic. Make sure the area
of use has adequate ventilation. Exposure to open flame converts
TRICLORETHANE to a highly toxic and dangerous gas.

Remove dust and dirt from plugs and receptacles.

Clean the front panel and control knobs using a soft clean cloth. If the dirt
is difficult to remove, dampen the cloth with mild detergent and water.
