Suspended Installation
CAUTION
●
The strength of the suspension points on the speaker is
per point (maximum).
●
Before doing any installation or construction work, consult
with an installation expert.
●
When choosing the installation location, suspension wire and
mounting hardware, make sure all are strong enough to
support the weight of the speaker.
●
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 improper installation.
