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 fire. 

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 effectiveness 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.
