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:
• 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 instrument. The
required voltage is printed on the name plate of the instrument.
• Check the electric plug periodically and remove any dirt or dust
which may have accumulated on it.
• This instrument contains no user-serviceable parts. Do not attempt
to disassemble or modify the internal components 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 instrument 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 instrument, turn off the
power immediately and unplug the power cord from the AC outlet.
Then have the instrument 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 instrument.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the instrument or other property. These precautions include, but are not limited to, the following:
• Do not connect the instrument to an electrical outlet using a
multiple-connector. Doing so can result in lower sound quality, or
possibly cause overheating in the outlet.
• When removing the electric plug from the instrument 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 instrument is not
to be used for extended periods of time, or during electrical storms.
• Do not place the instrument in an unstable position where it might
accidentally fall over.
• Before moving the instrument, remove all connected cables.
• When setting up the product, 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.
• Use only the stand/rack specified for the instrument. When attaching
the stand or rack, use the provided screws only. Failure to do so
could cause damage to the internal components or result in the
instrument falling over.
• Make sure to place the subwoofer unit away from walls or other
objects leaving space of at least 20cm (about 8 inches) above and
10cm (4 inches) on all sides. (The unit has a built in amplifier and
generates heat.) Also make sure not to lay the unit on any surface
with the rear panel facing down.
