PRECAUTIONS
PRECAUTIONS
Avoid placing the QX3 in direct sunlight or close to a source of heat. Also, avoid locations where the unit
is likely to be subjected to vibration, excessive dust, cold or moisture.
Avoid rough handling, such as applying excessive force to the switches or dropping the unit. While the
internal circuitry is of reliable integrated circuit design, the unit should be treated with care.
Always grip the plug directly when removing it from an AC outlet. Removing the plug from the AC outlet
by pulling the cord can result in damage to the cord and possibly a short circuit. It is also a good idea to
disconnect the QX3 from the AC outlet if you don't plan to use it for an extended period of time.
If necessary, clean the QX3 using a slightly damp cloth, and dry with a soft cloth.
Never use solvents
(such as benzine or thinner) since they can melt or discolor the finish.
All computer circuitry, including that in the QX3, is sensitive to voltage spikes. For this reason, the unit
should be turned off and unplugged from the AC outlet in the event of an electrical storm. This precaution
will avoid the chance that a high voltage spike caused by lightning will damage the unit.
Computer circuitry is also sensitive to electromagnetic radiation.
Be careful not to set it too close to
equipment (such as a television set) that generates electromagnetic fields. Proximity to such equipment
could cause malfunctions in the QX3's digital circuitry and interfere with the operation of the other unit.
When inserting a disk in the disk drive, make sure it is facing the correct way (label up).
This unit contains no user servicable parts. Opening it or tampering with it can lead to electrical shock
as well as damage, and will void the product warranty. Refer all servicing to qualified Yamaha personnel.
