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 or an equivalent recommended

by Yamaha).

• (DSP5D only) Use only the included power cord.

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.

• 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.

• (DSP5D only) 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.
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.

• 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 or 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.

• Turn the PM5D ON/OFF using only the power supply PW800W POWER switch.

Turning the PM5D ON/OFF by plugging or unplugging the power cord, using a
switch on a power tap, a breaker switch, or similar external means can result in
damage.

• When transporting or moving the device, always use four or more people

(PM5D), two or more people (DSP5D). Attempting to lift the device by yourself
may damage your back, result in other injury, or cause damage to the device
itself.

• Before moving the device, remove all connected cables.

• When setting up the DSP5D, 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 DSP5D is to be mounted in an EIA-standard rack, leave the back of the

rack open and make sure that it is at least 10 cm away from walls or surfaces.
Also, if the DSP5D is to be mounted with devices that tend to generate heat,
such as power amplifiers, be sure to keep an adequate gap between the DSP5D
and the heat-generating devices or install ventilation panels to prevent high
temperatures from developing inside the DSP5D. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.

• Do not use the DSP5D in a confined, poorly-ventilated location. If the DSP5D is

to be used in a small space other than an EIA-standard rack, make sure that
there is adequate space between the device and surrounding walls or other
devices: at least 10 cm behind and 10 cm above. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.
