 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:
• 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.
If you intend to use the device in an area other than in the one you purchased, 
the included power cord may not be compatible. Please check with your Yamaha 
dealer.
• 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.
• 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.
• 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.
• Do not put burning items, such as candles, on the unit. A burning item may fall 
over and cause a fire.
• 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.

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:
• 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.
• Do not place the device in an unstable position where it might accidentally fall 
over.
• Do not block the vents. This device has ventilation holes at the rear and sides to 
prevent the internal temperature from becoming too high. In particular, do not 
place the device on its side or upside down. Inadequate ventilation can result in 
overheating, possibly causing damage to the device(s), or even fire.
• If mounting this device in an EIA-standard rack, leave the back of the rack open, 
and keep the rack least 10 cm from the wall. If you mount this device in a rack 
together with a device that tends to generate heat, such as a power amp, take 
precautions to prevent heat from building up inside this device, for example by 
leaving space between the devices and by installing ventilation panels.
• 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.
