8. USING THE SUPPLIED SUSPENSION BRACkETS
(HX-7B and Hy-7W only)
The HX-7B and HX-7W speaker systems can be suspended in either vertical or horizontal orientation using the
supplied suspension brackets.
Before mounting the suspension brackets, lay out a protective sheet, corrugated cardboard or other soft material
on a flat surface, and perform all work on the speaker with its front baffle facing downward.
• Tighten the bolts securely, as instructed below.
Failure to follow instructions precisely could result in a falling speaker
and potential personal injury.
· Ensure that all bolts are securely inserted as far as their threads go,
then securely fasten each bolt with a nut.
· Tighten all the bolts with the designated tightening torque.
For tightening, use a Phillips screwdriver, or open- or box-end wrench.
• Owing to the speaker’s size and weight, be sure that at least two
persons are available for flying installation of the speaker. Failure to do
so could result in personal injury.
WARNING
Step 1. Detach the side angle bolts indicated by the arrows in the figure below.
The bolts to be detached defer depending on the speaker’s vertical or horizontal suspension orientation.
[Vertical suspension] [Horizontal suspension]
Note
The bolts on the opposite side of the speaker system can
also be detached for suspension bracket attachment.
