Cleaning the VCR
Use a soft cloth or dusting attachment of a
vacuum cleaner to remove dust from the
ventilation holes on the back sides and
bottom of the cabinet.
Plastic surfaces are easily scratched and
can be marred by alcohol and various
solvents. Avoid excessive use of oil-based
furniture polishes since the materials used
in the cabinet will accumulate more dust.
We recommend using a nonabrasive,
antistatic cleaner and polisher.
