Precautions
1. Location
Keep the unit away from locations where it is likely to be exposed to high tem-
peratures 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 bottom panel. 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 Modifications Yourself
This product contains no user-serviceable parts. Refer all maintenance to qual-
ified 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 disconnecting cables. This is
important to prevent damage to the unit itself as well as other connected equip-
ment.
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.
