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:
• 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 specified power supply (PW800W), if you use an external power
supply.
• 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.
• Be sure to connect to an appropriate outlet with a protective grounding
connection. Improper grounding can result in electrical shock.
• Do not open the device or attempt to disassemble the internal parts or modify
them in any way. The device contains no user-serviceable parts. 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 containers on it containing liquids which might spill into any openings.
• Never insert or remove an electric plug with wet hands.
• If the power cord or plug becomes frayed or damaged, or if there is a sudden
loss of sound during use of the device, or if any unusual smells or smoke
should appear to be caused by it, immediately turn off the power switch,
disconnect the electric plug from the outlet, and have the device inspected by
qualified Yamaha service personnel.
• If this device power supply 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:
• Remove the electric plug from the outlet when the device is not to be used for
extended periods of time, or during electrical storms.
• 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.
• When transporting or moving the device, always use two or more people.
Attempting to lift the device by yourself may damage your back, result in other
injury, or cause damage to the device itself.
• When transporting or moving the device, do not hold the display.
• Before moving the device, remove all connected cables.
• When setting up the device, make sure that the rear-panel power switch can be
easily turned ON/OFF. If some trouble or malfunction occurs, immediately turn
off the power switch and disconnect the plug from the outlet.
•Avoid setting all equalizer controls and faders to their maximum. Depending on
the condition of the connected devices, doing so may cause feedback and may
damage the speakers.
• Do not expose the device to excessive dust or vibrations, or extreme cold or heat
(such as in direct sunlight, near a heater, or in a car during the day) to prevent
the possibility of panel disfiguration or damage to the internal components.
• 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 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.
• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile
phone, or other electric devices. Doing so may result in noise, both in the device
itself and in the TV or radio next to it.
• 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.
• When connecting the device to PW800W, be sure to turn OFF the device and
PW800W, then, connect the power cable (PSL360).
• Be sure to connect to a properly grounded power source. A ground screw is
provided on the rear panel of this device for maximum safety and shock
prevention. If the mains outlet is not grounded, be sure to connect the ground
screw to a confirmed ground point before plugging the device into the mains.
Improper grounding can result in electrical shock.
