rive confidently knowing the most sophisticated anti-laser technology available is vigilantly detecting and protecting your vehicle. New Defuser EX & EX2 detects and deactivates the laser light signal transmitted by police laser guns by sending out a powerful return pulse signal at the same frequency. Simultaneously, you’re alerted to the targeting with audible and visual warnings, giving you the precious time you need to react and safely reduce your speed. Defuser EX & EX2 provide total protection against police laser. All new internal electronics feature more powerful laser emitters, improved laser detection capabilities and updated programming against the latest police laser technology. And Defuser EX & EX2’s design is almost 50% smaller than any previous Laser Defuser, so the systems blend discreetly into any vehicle and are virtually unnoticeable.

1. Installation
Instructions
& Recommended
Pr ocedures
The Defuser EX system is ideal for small to mid-size vehicles, and comes packaged in an ordinary looking
license plate frame. It may be installed with or without the license plate frame as needed.
The Defuser EX2 system is recommended for larger size vehicles, or when a front license plate mount
is not used on the vehicle. The system includes two separate Defuser modules with no license plate frames.
LASER DEFUSER EX
(FRONT LICENSE PLATE MOUNT WITH FRAME)
1. Remove the mounting bolts and any existing frame or cover from the license plate. Remove license plate.
2. Position the Laser Defuser EX around the existing front license plate and mount it against the factory license
plate bracket. Use the existing mounting bolts or K40 supplied nylon bolts to secure the Laser Defuser EX
frame and license plate to the bracket.
NOTE: On vehicles that have only one set of bracket mounting holes, it is recommended that the Laser
Defuser EX and the license plate be bolted together to eliminate any vibration.
3. For proper performance, the Defuser EX must be mounted completely level. A unit which is positioned up,
down, or to the side by as little as 1° can reduce jamming effectiveness by as much as several hundred feet
(see diagram A1).
To assure the Defuser EX is properly leveled, insert the rod on the K40 supplied level into the leveling assem-
bly hole located on the top of the Defuser EX frame (see diagram A2). Be sure that the vehicle is on a level
surface before checking installation.

NOTE: On some vehicles, it may be necessary to adjust or reposition the factory license plate bracket to
achieve the desired level installation.

2. LASER DEFUSER EX & EX2
(FRONT CUSTOM MOUNT WITHOUT FRAME)
NOTE: If using an EX system, first separate the module from the license plate frame by removing the
two screws on the backside of the frame.
1. For the single Defuser EX, choose a mounting location near the center of the vehicle that has a clear, unob-
structed view of the road . Units which are mounted off center, are recessed into the vehicle, or which are
obstructed in any way will not perform properly (see diagram B1).

2. For the dual Defuser EX2, choose separate mounting locations on either side of the license plate area and/or
center of the vehicle. For proper performance, the EX2 modules should be spaced 18" apart from one
another, and cannot be obstructed in any way or recessed into the vehicle (see diagram B2).

3. If utilizing the supplied universal mounting bracket(s), determine which holes will be used to mount the
Defuser module(s) to the vehicle. Remove the unused mounting tabs on the bracket(s) as needed.
4. Apply the supplied double stick tape directly to the Defuser module(s) and attach the module(s) to the
universal mounting bracket(s) with the included 1/4” screws ( diagram B3).
