Precautions
Electrical Interference
The 9000 uses digital circuitry that may cause interference and noise if placed too close
to other electrical equipment, such as TV sets and radio receivers. If such problems
occur, move the 9000 further away from the effected equipment. Also, when fluorescent
lights or devices with built-in motors are in close proximity to the 9000, the 9000 may
not function properly.
Cleaning
Use a soft, dry cloth to clean the 9000. If necessary, a slightly damp cloth can also be
used. Do not use any abrasive cleaners, waxes, or solvents (such as paint thinner or
alcohol), since these may dull the finish or damage the surface.
About Troubles
If any difficulty arises during operation, or the 9000 malfunctions, unplug the 9000 and
disconnect the cables connected to the IN/POWER connector, and then also disconnect
the other cables from the 9000. Contact the shop from which you have purchased the
9000 with the following information: model name; serial number; symptom; your name,
address and phone number.
Keep this manual in a safe, convenient place for future
reference.
