The use of this or any warning device does not ensure that all drivers can or will observe or react to
an emergency warning signal. Never take the right-of-way for granted. It is your responsibility to be
sure you can proceed safely before entering an intersection, driving against traffic, responding at a
high rate of speed, or walking on or around traffic lanes.
The effectiveness of this warning device is highly dependent upon correct mounting and wiring.
Read and follow the manufacturer’s instructions before installing or using this device. The vehicle
operator should insure daily that all features of the device operate correctly. In use, the vehicle
operator should insure the projection of the warning signal is not blocked by vehicle components (i.e.:
open trunks or compartment doors), people, vehicles, or other obstructions.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to
understand and obey all laws regarding emergency warning devices. The user should check all ap-
plicable city, state and federal laws and regulations.
Code 3, Inc., assumes no liability for any loss resulting from the use of this warning device.
Proper installation is vital to the performance of this warning device and the safe operation of the
emergency vehicle. It is important to recognize that the operator of the emergency vehicle is under
psychological and physiological stress caused by the emergency situation. The warning device
should be installed in such a manner as to: A) Not reduce the output performance of the system, B)
Place the controls within convenient reach of the operator so that he can operate the system without
losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Properly protect
and use caution around live electrical connections. Grounding or shorting of electrical connections
can cause high current arcing, which can cause personal injury and/or severe vehicle damage,
including fire.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF
EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY
PERSONNEL AND THE PUBLIC.
Unpacking & Pre-installation

the cable coming out of the bottom. Examine the unit for transit damage, broken lamps, etc. Report any
damage to the carrier and keep the shipping carton.
The LED DuoBeam II
TM
is built to operate on 12 volt D.C. negative ground (earth) vehicles. If you have an
electrical system other than 12 volt D.C. negative ground (earth) contact the factory.
