 Owner’s Manual

* Please keep this manual in a safe place for future reference.

• 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 instrument.
- 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.

• 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 front and side 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.

• To avoid damage, do not install or store the device in a place subject to salty air 

or corrosive gas or chemicals.

• 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.

• If the device is mounted in an EIA standard rack, carefully read the section 

“Precautions for Rack Mounting” on page 8. Inadequate ventilation can result in 
overheating, possibly causing damage to the device(s), malfunction, or even fire.

• Keep device away from the reach of children.

• Before connecting the device to other devices, turn off the power for all devices. 

Before turning the power on or off for all devices, set all volume levels to 
minimum.

• Remove the power plug from the AC outlet when cleaning the device.

• Do not insert your fingers or hands in any gaps or openings on the device 

(vents, etc.).

• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any 

gaps or openings on the device (vents, etc.) If this happens, turn off the power 
immediately and unplug the power cord from the AC outlet. Then have the 
device inspected by qualified Yamaha service personnel.

• Do not rest your weight on the device or place heavy objects on it, and avoid use 

excessive force on the buttons, switches or connectors.

• Do not use speakers for a long period of time at a high or uncomfortable volume 

level, since this can cause permanent hearing loss. If you experience any 
hearing loss or ringing in the ears, consult a physician.
