DH-110

DH-120

STRAIGHT HORN SPEAKER

INSTRUCTION MANUAL

Indicates a potentially hazardous situation which, if mishandled, could result in death or

serious personal injury.

WARNING

• The standard supplied mounting bracket is not designed for use in locations exposed to strong winds and could become

dislodged, resulting in possible personal injury. To ensure that the installation can withstand expected wind forces,

always use the supplied mounting bracket in combination with a separately prepared bracket.

• 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 ceiling's or wall'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.
