FEATURE DESCRIPTIONS

Installation

• Locate the tab near the button openings and 

insert this end first into the unit.

• Gently snap in the other tabs as you work your 

way to the back of the unit.

Mounting Guidelines

• Mount the unit as low as possible near the center 

of the windshield.  

• Do not mount your unit behind wipers, 

ornaments, mirrored sunscreens, etc. These 
obstructions have metal surfaces which can affect 
radar and laser signals and reduce critical warning
time. (Regular tinted glass does not affect 
reception.)

or  

Electriclear

type coating, which affect radar signals.

Consult your dealer or the vehicle’s owner’s manual to

determine if your windshield has this coating.
• Avoid placing unit in direct contact with windshield.
• Avoid placing unit in direct sunlight.
• To reduce the possibility of theft, conceal your 

unit when not in use.

Windshield Mounting

• Install the two suction cups and rubber bumper 

onto the bracket by fitting them into their holes.

Press the suction cups onto the windshield at the 
location you have chosen.

Slide the detector onto the bracket until it locks into 

place.

• If necessary, the unit may be leveled by bending the 

windshield bracket. 

• Press the bracket release button and remove the 

detector before bending.
