Additional Information
Power transformer – Power filters and conditioners
It is a normal phenomenon that the device’s power transformer may generate a certain amount of
audible noise.
Very loud operation of the power transformer may be caused by low quality of power supply
(voltage surges etc.).
In such a case, we suggest using a power filter or conditioner - you can also try to power this pro-
duct from a different power line than other devices (e.g. from a power outlet in another room).
Handling of CD discs
Playback side
• 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.
• If you cannot wipe off the dust with a soft cloth, wipe the disc lightly with a slightly moistened
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.
Storing Discs
• Do not store discs in places subjected to direct sunlight or near heat sources.
• Do not store discs in places subjected to moisture and dust such as a bathroom or near a
humidifier.
• Storing discs vertically in a case, stacking discs or placing objects on discs outside of their
cases may cause warping.
