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 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, and also 
disconnect the connected power supply from the [BACKUP 
DC INPUT] connector. 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, and also disconnect the 
connected power supply from the [BACKUP DC INPUT] 
connector. Then have the device inspected by qualified 
Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

Hearing loss

• Before connecting the device to other devices, turn off the 

power for all devices. Failing to do so may result in hearing 
loss, electric shock, or device damage.

• When turning on the 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 and also disconnect the connected power supply 
from the [BACKUP DC INPUT] connector.
- 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 or the power supply should be dropped or 

damaged, immediately turn off the power switch, 
disconnect the electric plug from the outlet and also 
disconnect the connected power supply from the [BACKUP 
DC INPUT] connector, and then have the device inspected 
by qualified Yamaha service personnel.
