of parts that could be damaged; such as brake lines,
fuel lines, electrical wiring or other vital parts.

to the speaker, ensure that the speaker is mounted
with the wires exiting from the right side of the speaker
when looking at it from the front.

lockwashers.

WARNING
All effective sirens produce loud sounds which
may cause, in certain situations, permanent hearing
loss. You should take appropriate precautions such
as wearing hearing protection.

E. OPERATION.
Refer to the instructions packed with the electronic
siren for operation.
SAFETY MESSAGE TO OPERATORS
Listed below are some important safety
instructions and precautions you should follow:
• All effective sirens produce loud sounds
which may cause, in certain situations, permanent
hearing loss. You should take appropriate
precautions such as wering hearing protection.
• You hearing and the hearing of others, in or
close to your emergency vehicle, could be damaged
by loud sounds. This can occur from short exposures
to very loud sounds, or from longer exposures to
moderately loud sounds. For hearing conservation
guidance, refer to federal, state, or local
recommendations. OSHA Standard 1910.95 offers
guidance on ''Permissible Noise Exposure''.
•
Optimum sounds propagation will be
reduced if speaker becomes clogged with a foreign
substance such as mud or snow. While removing a
foreign substance, ensure that it is not packed into
the speaker.
• Although your warning system is operating
properly, it may not be completely effective. People
may not hear, see, or heed your warning signal.
You must recognize this fact and continue driving
cautiously.
• Also, situations may occur which obstruct
your warning signal when natural or manmade
objects are between your vehicle and others. If these
situations occur, be especially careful.
• It is important that you fully understand how
to safely operate this warning system before use.
Failure to follow all safety precautions and
instructions may result in property damage, serious
injury, or death to you, to passengers, or to others.
F. SERVICE.
