Safety Messages
• It is important that you fully understand how to safely operate this warning system
before use.
• Only operate your vehicle and its light/sound system per your department’s
Standard Operating Procedures.
• If a selected function does not perform properly or if any of the lamps remain
illuminated when the control is off, disconnect the power connector from the control
unit and contact the nearest service center.
• At the start of your shift, you should ensure that the entire warning light system
and the siren system is securely attached and operating properly.
• Suction cup mounting is for temporary applications only. The unit should be
removed from the window and stored securely when not in use. Temperature
changes and sunlight can cause suction cups to lose holding power. Periodically
check the unit to be sure the suction cups have a firm grip on the mounting
surface. An improperly secured light could fall off of the vehicle causing injury and
damage.
• Holding power of magnetic mounting systems is dependent upon surface finish,
surface flatness, and thickness of the steel mounting surface. Therefore, to
promote proper magnetic mounting:
• Mounting surface and magnets must be kept clean, dry, and free of foreign
particles that prevent good surface contact.
• Ensure that mounting surface is flat.
• A magnet mounting system should not be used on vehicles with vinyl tops.
• To prevent sliding of light assembly on mounting surface, quick acceleration
and hard stops should be avoided.
Failure to follow these precautions may result in property damage, serious injury, or
death.
