Precautions
Water warning
Do not expose the device to rain, use it near water or in damp or wet conditions, or place con-
tainers on it containing liquids which might spill into any openings.
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 which are sub-
ject to excessive dust accumulation. Extreme vibrations 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 10cm or more between the
rear of the unit and the wall. This will prevent heat build-up inside the unit and possible fire haz-
ard.
Do not open the unit, or attempt repairs or modifications yourself
This product contains no user-serviceable parts. Prefer all maintenance to qualified Yamaha ser-
vice personnel. Opening the unit and/or tampering with the internal circuitry will void the war-
ranty.
Make sure the power is off before making or removing connections
Always turn the power OFF prior to connecting or disconnecting cables. This is important to pre-
vent 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.
Always use the correct power source
Make sure the power source voltage specified on the rear panel matches your local AC mains
supply:
US & Canadian Model: 120V AC, 60 Hz
General Model: 230V AC, 50 Hz
UK Model: 240V AC, 50 Hz
Back-up battery
This unit contains a long-life lithium battery which maintains the contents of user memory loca-
tions even when the unit is off. With normal use, the battery should last approximately five
years. If the battery voltage falls below a certain level, the message "WARNING LOW BAT-
TERY" will appear on the screen when the power is turned on. If this occurs, have the battery
replaced at a qualified Yamaha service center.
Warning: DO NOT ATTEMPT TO REPLACE THE BATTERY YOURSELF. OPENING THE UNIT
AND/OR TAMPERING WITH THE INTERNAL CIRCUITRY WILL VOID THE WARRANTY.
