Precautions
1. Location
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 excessive dust accumulation or vibration which
could cause mechanical damage and locations subject to
strong electromagnetic fields, such as close to broadcast
equipment.
2. Ventilation
The unit has ventilation slots on the side and bottom
panels. Do not block these vents.
3. Avoid Physical Shocks
Strong physical shocks to the unit can cause damage.
Handle it with care.
4. Do Not Open the Case or Attempt Repairs or Modifi-
cations 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 connections
Always turn the power OFF before connecting or discon-
necting cables. This is important to prevent damage to the
unit itself as well as other connected 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.
