PRECAUTIONS
PLEASE READ CAREFULLY 
BEFORE PROCEEDING 
Please keep this manual in a safe place for 
future reference.

 WARNING

Always follow the basic precautions listed below to avoid 
the possibility of serious injury or even death from 
electrical shock, short-circuiting, damages, fire or other 
hazards. These precautions include, but are not limited 
to, the following:

Power supply/power cord 

• Do not place the power cord near heat sources such as 

heaters or radiators, and do not excessively bend or otherwise 
damage the cord, place heavy objects on it, or place it in a 
position where anyone could walk on, trip over, or roll anything 
over it.

• Only use the voltage specified as correct for the device. The 

required voltage is printed on the name plate of the device.

• Use only the supplied power cord/plug.

• Check the electric plug periodically and remove any dirt or 

dust which may have accumulated on it.

• Be sure to connect to an appropriate outlet with a protective 

grounding connection. Improper grounding can result in 
electrical shock, damage to the device(s), or even fire.

Do not open

• This device contains no user-serviceable parts. Do not open 

the device or attempt to disassemble the internal parts or 
modify them in any way. If it should appear to be 
malfunctioning, discontinue use immediately and have it 
inspected by qualified Yamaha service personnel.

Water warning

• Do not expose the device to rain, use it near water or in damp 

or wet conditions, or place on it any containers (such as 
vases, bottles or glasses) containing liquids which might spill 
into any openings. If any liquid such as water seeps into the 
device, turn off the power immediately and unplug the power 
cord from the AC outlet. Then have the device inspected by 
qualified Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

Fire warning

• Do not put burning items, such as candles, on the unit. 

A burning item may fall over and cause a fire.

If you notice any abnormality

• When one of the following problems occur, immediately turn 

off the power switch and disconnect the electric plug from the 
outlet. Then have the device inspected by Yamaha service 
personnel.
- The power cord or plug becomes frayed or damaged.
- It emits unusual smells or smoke.
- Some object has been dropped into the device.
- There is a sudden loss of sound during use of the device.

• If this device should be dropped or damaged, immediately 

turn off the power switch, disconnect the electric plug from the 
outlet, and have the device inspected by qualified Yamaha 
service personnel.

 CAUTION

Always follow the basic precautions listed below to avoid 
the possibility of physical injury to you or others, or 
damage to the device or other property. These 
precautions include, but are not limited to, the following:

Power supply/power cord

• When removing the electric plug from the device or an outlet, 

always hold the plug itself and not the cord. Pulling by the 
cord can damage it.

• Remove the electric plug from the outlet when the device is 

not to be used for extended periods of time, or during 
electrical storms.

Location

• Do not place the device in an unstable position where it might 

accidentally fall over.

• Do not use the device in a confined, poorly-ventilated location. 

Make sure that there is adequate space between the device 
and surrounding walls or other devices: at least 20cm at the 
sides, 20cm behind and 20cm above. Inadequate ventilation 
can result in overheating, possibly causing damage to the 
device(s), or even fire.

• Do not hold the bottom of the device when transporting or 

moving it. In doing so, you may pinch your hands under the 
device, and result in injury.

• Do not press the rear panel of the device against the wall. 

Doing so may cause the plug to come in contact with the wall 
and detach from the power cord, resulting in short circuiting, 
malfunction, or even fire.

• Do not place the device in a location where it may come into 

contact with corrosive gases or salt air. Doing so may result in 
malfunction.

• Before moving the device, remove all connected cables.

• When setting up the device, make sure that the AC outlet you 

are using is easily accessible. If some trouble or malfunction 
occurs, immediately turn off the power switch and disconnect 
the plug from the outlet. Even when the power switch is turned 
off, electricity is still flowing to the product at the minimum 
level. When you are not using the product for a long time, 
make sure to unplug the power cord from the wall AC outlet.
