Precautions
1. 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, etc.
Also avoid locations which are subject to exces-
sive dust accumulation or vibration which could
cause mechanical damage.
2. Ventilation
The unit has ventilation slots on the top, rear and
bottom panels. Do not block these vents.
3. Avoid physical shocks, liquid and small
metal objects
Strong physical shocks to the unit can cause dam-
age. Handle it with care.
Do not place a container with liquid or small
metal objects on top of this unit. Liquid or metal
objects inside this unit are a fire and electrical
shock hazard.
4. Do not open the case or attempt repairs
or modifications yourself
This product contains no user-serviceable parts.
Refer all maintenance to qualified Yamaha service
personnel. Opening the case and/or tampering
with the internal circuitry voids the warranty.
5. Always power off before making connec-
tions
Always turn the power OFF before connecting or
disconnecting cables. This is important to pre-
vent damage to the unit itself as well as other con-
nected equipment.
6. Handle cables carefully
Always plug and unplug cables - including the
AC power cord - by gripping the connector, not
the cord.
7. Clean with a soft dry cloth
Never use solvents such as benzine or thinner to
clean the unit. Wipe clean with a soft, dry cloth.
8. Always use the correct power supply
Make sure that the power supply voltage specified
on the rear panel matches your local AC mains
supply. Also make sure that the AC mains supply
can deliver more than enough current to handle
all equipment used in your system.
