 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 device. The 
required voltage is printed on the name plate of the device.
• Use only the supplied power cord/plug.
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. Improper grounding can result in 
electrical shock, damage to the device(s), or even fire.
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
• When turning on the AC power in your audio system, always 
turn on the power amplifier LAST, to avoid hearing loss and 
speaker damage. When turning the power off, the power 
amplifier 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.
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.
- Some object has been dropped into the device.
- There is a sudden loss of sound during use of the device.
- Cracks or other visible damage appear on the device.
Then have the device inspected or repaired 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:
Power supply/power cord
• 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.
Location
• Do not place the device in an unstable position where it 
might accidentally fall over and cause injuries.
• Do not block the vents. This device has ventilation holes at 
the front/rear/sides 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 place the device in a location where it may come into 
contact with corrosive gases or salt air. Doing so may result 
in malfunction.
• Before moving the device, remove all connected cables.
• If the device is mounted in an EIA standard rack, carefully 
read the section “Precautions when rackmounting” on page 
8. Inadequate ventilation can result in overheating, possibly 
causing damage to the device(s), malfunction, or even fire.
