PRECAUTIONS

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:

• Before doing any installation or construction work, consult with an installation expert.

• Make sure that the surface this bracket is being mounted on has the strength to handle the weight of both the speaker and this

• Use bolts and nuts as well as washers for installation and tighten them firmly so that the speaker is secure and does not move.

• Always loosen the corresponding screw before adjusting the angle or direction of the speaker. Never force this adjustment with
the screw still tightened.

• Some fittings may deteriorate over extended periods of time due to wear and/or corrosion. For optimum safety, the installation
should be checked thoroughly at regular intervals.

Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support structure or
