WARNING Indicates a potentially hazardous
situation which, if mishandled, could result in death or
serious personal injury.
• Install the unit only in a location that can structurally
support the weight of the unit and the mounting bracket.
Doing otherwise may result in the speaker falling down
and causing personal injury and/or property damage.
• Owing to the speaker's size and weight, be sure that at
least two persons are available to install the speaker.
Failure to do so could result in personal injury.
• Be sure to follow these instructions closely when
installing the HY-0851ST or HY-0852ST bracket to
prevent falls of the bracket due to corrosion, etc., which
could result in personal injury.
· Because the HY-0851ST and HY-0852ST cannot be
used alone, be sure they are installed in combination
with another specified bracket.
· The HY-0801ST and HY-0852ST are designed for
indoor use only. Do not install outdoors.
•
Tighten each nut and bolt securely. Ensure that the HY-
0851ST and HY-0852ST have no loose joints after
