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:
Power supply/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.
• Only use the voltage specified as correct for the mixer.
The required voltage is printed on the name plate of the
mixer.
• Use only the supplied 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.
• Check the electric plug periodically and remove any dirt
or dust which may have accumulated on it.
• 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, as long as the power cord is
not unplugged from the wall AC outlet, the device will not
be disconnected from the power source.
• Remove the electric plug from the outlet when the device
is not to be used for extended periods of time, or during
electrical storms.
• Be sure to connect to an appropriate outlet with a
protective grounding connection.
Do not open
• 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.
Water warning
• 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.
Hearing loss
• Avoid setting all equalizer controls and level controls to
their maximum. Depending on the condition of the
connected devices, doing so may result in feedback that
can cause hearing loss and damage the speakers.
• Before connecting the device to other devices, turn off the
power for all devices. Also, before turning the power of all
devices on or off, make sure that all volume levels are set
to the minimum. Failing to do so may result in hearing loss,
electric shock, or device damage.
• When turning on the AC power in your audio system,
always turn on the device LAST, to avoid hearing loss and
speaker damage. When turning the power off, the device
should be turned off FIRST for the same reason.
Fire warning
• Do not place any burning items or open flames near the
device, since they may cause a fire.
Wireless unit
• Do not use this device near medical devices or inside
medical facilities. Radio waves from this device may affect
electro-medical devices.
• Do not use this device within 15 cm (6 in) of persons with
a heart pacemaker implant or a defibrillator implant. Radio
waves from this device may affect electro-medical
devices, such as a heart pacemaker implant or
defibrillator implant.
If you notice any abnormality
• If any of the following problems occur, immediately turn off
the power switch and disconnect the electric plug from
the outlet.
- The power cord or plug becomes frayed or damaged.
- Unusual smells or smoke are emitted.
