1. Proper installation combined with operator training in the use, care, and maintenance of emergency warning devices are essential to
ensure the safety of emergency personnel and the public.
2. Emergency warning devices often require high electrical voltages and/or currents. Exercise caution when working with live electrical
connections.
3. This product must be properly grounded. Inadequate grounding and/or shorting of electrical connections can cause high current arcing,
which can cause personal injury and/or severe vehicle damage, including re.
4. Proper placement and installation is vital to the performance of this warning device. Install this product so that output performance of
the system is maximized and the controls are placed within convenient reach of the operator so that they can operate the system without
losing eye contact with the roadway.
5. Do not install this product or route any wires in the deployment area of an air bag. Equipment mounted or located in an air bag
deployment area may reduce the e󰀨ectiveness of the air bag or become a projectile that could cause serious personal injury or death.
Refer to the vehicle owner’s manual for the air bag deployment area. It is the responsibility of the user/operator to determine a suitable
mounting location ensuring the safety of all passengers inside the vehicle particularly avoiding areas of potential head impact.
