Maintenance
Cleaning the Unit
Ensure the unit is fully unplugged from the mains socket before cleaning.
When cleaning the speakers without grills, beware of making a punch or push a small dent on a speaker’s
dust cap. These damages might affect the speaker’s performance.
Handling Discs
• Do not touch the playback side of the disc.
• Do not attach paper or tape to the disc.
Cleaning Discs
• Fingerprints and dust on the disc cause picture and sound deterioration. Wipe the disc
from the centre outwards with a soft cloth. Always keep the disc clean.
Playback side
• To clean the units, wipe the case with a slightly moist, lint-free cloth.
• Do not use any cleaning fluids containing alcohol, ammonia or abrasives.
• Do not spray aerosol at or near the unit.
Removing, Installation the Grill and Cleaning the Speakers
The grill is held by pins. To remove the grill, pull gently around the edge away from the
speaker, slowly working your way from one end of the speaker to the other.
To re-install, align the grill pins with the cups in the speaker and push into place.
Use a dampened soft cloth or paper towel to clean the cabinet. The grill is best cleaned by
brushing it off with a lint-free cloth.
• If you cannot wipe off the dust with a soft cloth, wipe the disc lightly with a slightly
moistened soft cloth and finish with a dry cloth.
• Do not use any type of solvent such as thinner, benzine, commercially available
cleaners or antistatic spray. They may damage the disc.
