personal injury.
WARNING
• Install the speaker only in a location that can
structurally support the weight of the speaker and
the mounting bracket. Doing otherwise may result
in the speaker falling down and causing personal
injury and/or property damage.
• Since the speaker is designed for indoor use, do
not install it outdoors. If installed outdoors, the aging
of parts causes the speaker to fall off, resulting in
personal injury. Also, when it gets wet with rain,
there is a danger of electric shock.
• Donotuseothermethodsthanspeciedtomount

and the speaker could fall off, possibly resulting in
personal injuries.

• Do not operate the speaker for an extended period
of time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
