Safe Mounting and Operation of the Horn Speaker
Before installation or use, be sure to carefully read all the instructions in this section for
correct and safe installation and operation. After reading, keep this document handy for
future reference.
Warning Incorrect installation of the horn speaker may result in death or serious
injury. The horn speaker could break loose due to the extreme forces applied during
a collision or braking.
■ Install the horn speaker only to a mounting surface or structural element and
in a location that can structurally support the weight of the horn speaker
(13.2lbs [1.4 kg]) during a collision.
■ Use nuts and bolts that are appropriate for the mounting surface’s structure
and composition.
■ Tighten each nut and bolt securely. Ensure that the mounting bracket has no
loose joints after installation.
■ Check regularly whether the horn speaker is still secure and hasn’t corroded.
Retighten or replace if necessary.
Warning Attach a safety wire to the unit when mounting in locations high above
the ground.
Warning Choose a mounting position for the horn speaker where it will not interfere with the operation of any of the vehicle controls.
Warning When drilling holes in the vehicle, check that drilling at the selected
points will not damage existing wiring, petrol tanks, fuel and brake lines, or battery
cables.
Warning To avoid accidental air explosions, do not use the unit around gasoline,
thinner or other combustibles.
Warning Protect the unit from exposure in snowy areas, as the weight of snow
build-up could cause the speaker to down or drop.
Warning Do not operate the horn 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.
Caution Do not stand or sit on, nor hang down from the horn speaker as this may
cause the speaker to fall down or drop.
Notice When installing the horn speaker, be sure that water and snow cannot accumulate inside the horn.
