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 which are subject to
excessive dirt accumulation. Extreme vibrations can cause mechanical damage.
Avoid physical shocks
Strong physical shocks can damage the unit. Handle it with care.
Do not open the unit, or attempt repairs or modifications yourself
This product contains no user-serviceable parts. Refer all maintenance to qualified Yamaha service
personnel. Opening the unit and/or tampering with the internal circuitry will void the warranty.
Make sure power is off before making or removing connections
Always turn the power OFF prior to connecting or disconnecting 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.

locations 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 “

appear on the screen when the power is turned on. If this occurs, have the battery replaced at a
qualified Yamaha service center.
