Safety Messages to Operators of Federal Signal Sound/Light Systems
People’s lives depend on your safe operation of Federal Signal products. It is
important to read and follow all instructions shipped with the products. Listed below
are some other important safety instructions and precautions you should follow.
• Do not attempt to activate or deactivate the controls of the emergency warning
system while driving in a hazardous situation.
• Although your warning system is operating properly, it may not be completely
effective. People may not see, hear, or heed your warning signal. You must
recognize this fact and continue to drive cautiously.
• Situations may occur that obstruct your warning signal when natural and man-
made objects are between your vehicle and others, such as raising your hood or
trunk lid. If these situations occur, be especially careful.
• All effective sirens and horns produce loud sounds that may cause, in certain
situations, permanent hearing loss. You and your passengers should consider
taking appropriate safety precautions, such as wearing hearing protection.
• The effectiveness of an interior mounted warning light depends on the clarity, the
tinting, and the angle of the glass it is being placed behind. Tinting, dirt, defects,
and steeply angled glass reduce the light output of the warning light. This may
reduce the effectiveness of the light as a warning signal. If your vehicle has dirty,
tinted, or steeply angled glass, use extra caution when driving your vehicle or
blocking the right of way with your vehicle.
• In order to be an effective warning device, this product produces bright light that
can be hazardous to your eyesight when viewed at a close range. Do not stare
directly into this lighting product at a close range, or permanent damage to your
eyesight may occur.
