Caution
•
Construction work should be carried out by a professional
constructor.
•
Do not install the speaker transversely.
•
Make sure not to touch the cone when installing.
•
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, or the mounted parts may
loosen.
•
When choosing the installation location such as wall and ceiling and
mounting hardware (bolts, nuts), make sure all are strong enough to
support the weight of the speaker.
•
Make sure to properly use the safety wire to prevent the speaker from
falling down in the event of an installation failure.
•
When installing the safety wire to the ceiling or wall, install it higher
than the wire's attachment point on the speaker to reduce slack. Also,
ensure that the installation height and location would pose no danger
to people should the speaker fall.
•
Yamaha does not assume any responsibilities for accidents such as
dropping due to insufficient strength at attachment points or
inadequacy of the mounting method.
•
The recommended tightening torque for installing the included screws
for bracket installation is 6.2 Nm for the M8 screw (HS8I and HS7I)
and 2.4 Nm for the M5 screw (HS5I).
•
Use safety wires with the following specifications.
NOTE
Do not use the speaker if the screws at locations where
brackets are not installed have been removed. This causes air
leaks to occur from the enclosure, resulting in undesirable
performance.
