Yamaha ProR3 Manuale Utente

 

Precautions   

 

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.

 

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.

 

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.

 

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.

 

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.

 

Always plug and unplug cables – including the AC cord – by gripping the connector, not the 
cord.

 

Never use solvents such as benzine or thinner to clean the unit. Wipe it clean with a soft, dry 
cloth.

 

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

 

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.
