INSTRUCTION MANUAL
• 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.
• Use nuts and bolts that are appropriate for the
installation place's structure and composition.
Failure to do so may cause the speaker to fall,
resulting in material damage and possible personal
injury.
• 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.
• Attach the safety wire to the unit when mounting in
locations high above the ground. Failure to do so
could result in personal injury if the speaker should
later fall for any reason.
• Protect the unit from exposure in snowy areas,
as the weight of snow build-up could cause the
speaker to fall, resulting in personal injury.
