Note
In order to prevent the unit from falling down, attach the safety wire as
shown in the illustration.
CAUTION
• Before doing any installation or construction work, consult with your Yamaha dealer.
• For optimum safety, the installation should be checked thoroughly at regular intervals. Some fittings may deteriorate
over extended periods of time due to wear and/or corrosion.
• When choosing the installation location, suspension wire and mounting hardware, make sure all are strong enough to
support the weight of the speaker.
• Make sure to take measures to prevent the speaker from falling down in the event of a installation failure.
• When installing the safety wire to the wall, install it higher than the wire’s attachment point on the speaker, with as little
slack as possible. If the wire is too long, and the speaker happens to fall, the wire may snap as a result of too much
strain.
Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support
structure or improper installation.
