1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read
all the instructions in this section for correct and
safe operation.
• Be sure to follow all the precautionary instructions
in this section, which contain important warnings
and/or cautions regarding safety.
• After reading, keep this manual handy for future
reference.
• 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 unit falling down and causing personal injury
and/or property damage.
• Do not use other methods than specified to mount
the bracket. Extreme force is applied to the unit
and the unit could fall off, possibly resulting in
personal injuries.
• Tighten each nut and bolt securely. Ensure that the
bracket has no loose joints after installation to
prevent accidents that could result in personal
injury.
• Use the specified In-wall electrical box in
combination. Doing otherwise may cause the unit
or component to fall off, resulting in personal injury.
• Do not operate the unit 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.
• Do not stand or sit on, nor hang down from the unit
as this may cause it to fall down or drop, resulting
in personal injury and/or property damage.
