Precautions
Avoid excessive heat, humidity, dust,
and vibration
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity—such as near
radiators, stoves, in direct sunlight, etc. Avoid locations that
are subject to excessive dust accumulation. Extreme vibra-
tions can cause mechanical damage.
Avoid physical shocks
Strong physical shocks can damage the unit. Handle it with
care.
Install the unit with plenty of space for ventilation
This unit should be installed in such a way as to maintain a
gap of 10 cm or more between the rear of the unit and the
wall. This will prevent heat build-up inside the unit and pos-
sible fire hazard.
Do not open the unit, or attempt
repairs or modifications yourself
This product contains no user-serviceable parts. Prefer all
maintenance to qualified Yamaha service personnel. Open-
ing the unit and/or tampering with the internal circuitry will
void the warranty.
Make sure the power is off before
making or removing connections
Always turn the power OFF prior to connecting or discon-
necting cables. This is important to prevent damage to the
unit itself as well as other connected equipment.
Handle cables carefully
Always plug and unplug cables—including the AC cord—by
gripping the connector, not the cord.
Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the
unit. Wipe it clean with a soft, dry cloth.
