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 supplied 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.
• 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 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.
• Before moving the device, remove all connected cables.
• 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 use the device in the vicinity of a TV, radio, stereo equipment, mobile
phone, or other electric devices. Otherwise, the device, TV, or radio may
generate noise.
• 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.
• Be sure to connect to a properly grounded power source. A ground screw
terminal is provided on the rear panel for safely grounding the device and
preventing electrical shock.
• Do not insert your fingers or hand in any gaps or openings on the device.
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device. 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.
• This device has a built-in backup battery. When you unplug the power cord from
the AC outlet, the internal data is retained. However, if the backup battery fully
discharges, this data will be lost. When the backup battery is running low, the
GAIN display indicates “E1.” In this case, immediately have qualified Yamaha
service personnel replace the backup battery.
XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualifi ed Yamaha service
personnel about replacing defective components.
