shock, short-circuiting, damages, ﬁre or other hazards. These precautions include, but are not limited to, the following:

Do not open

• Do not open the device or attempt to disassemble the inter-

nal parts or modify them in any way. The device contains

no user-serviceable parts. If it should appear to be mal-

functioning, discontinue use immediately and have it

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:

Location

• If you use a stand, check the stand's speciﬁcations and

make sure that it is sturdy enough to support the weight of

the speaker. You may need to limit the number of people

around the placed stand, in order to avoid toppling the

device or causing damage to the internal components.

• If you use speaker stands, be sure to keep the following

cautions.

– Use the speaker stands with their legs fully opened.

– Mount only one speaker on each speaker stand.

– Tighten fastening screws securely.

– Remove the speakers from the stands before moving

the stands or adjusting their height.

– Add weight such as sand bags around the stand legs to

prevent them from falling over.

– Use the stand at a maximum height of 140cm (55").

• If you use a metal socket of the CW115V/CW118V sub-

woofer to allow mounting of a satellite speaker, use a pole

shorter than 90cm (35.4") with an outer diameter of 35mm

(1-3/8").

• When transporting or moving the device, always use two or

more people.

• Before moving the device, remove all connected cables.

• Do not use the speaker's handles for suspended installa-

tion. Doing so can result in damage or injury.

• Do not expose the device to excessive dust or vibrations,

or extreme cold or heat (such as in direct sunlight, near a

heater) 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.
