Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
HORN SPEAKER INSTRUCTION MANUAL
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
CAUTION
• Use only the specified amplifier output voltage and
impedance, as exceeding the specified limits could
result in fire or other failures (high-impedance
version).
• To avoid accidental air explosions, do not use the
unit around gasoline, thinner or other combustibles.
• 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.
• 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.
• 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.
• 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.
• 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.
• Avoid mounting the unit in locations exposed to
constant vibration. The mounting bracket can be
damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
• To avoid electric shocks, be sure to switch off the
amplifier power when connecting the speaker.
• Avoid installing the unit in humid or dusty locations,
or in locations exposed to heaters, solvents, acid,
alkali, smoke, steam or direct sunlight (except
outdoor-use versions), as excessive exposure to
these factors could result in speaker failure, fire or
electric shock.
• 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.
• Have the unit periodically checked by the shop
from where it was purchased. Also, when mounting
the unit on a vehicle, be sure to check both the
speaker and its mounts before moving. Failure to
do so could result in the speaker falling off due to
damage or corrosion to the speaker or its mounts,
and possible personal injury.
