Maintenance and Prevention
Your QDSP-2020 system requires minimal maintenance and care to keep it
operating correctly.
Occasionally wipe the system with a soft dry cloth.
You should only remove persistent dirt by use of a soft, slightly damp cloth (use
only a mild detergent).
Make sure the ventilation holes are clear of debris.
