• Total Band Protection

™

- Complete Band

Coverage that detects laser, radar, VG-2 and safety
radar bands.

Mounting Guidelines

• Mount the unit as low as possible near the center of 

the windshield.  

• Do not mount the 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.)

• Some windshields have an Instaclear

™

or Electriclear

™

type coating, which affects radar signals. Consult your 
dealer or the owner’s manual to determine if your 
windshield has this coating.

• Avoid placing unit in direct contact with the wind

shield.

• To reduce the possibility of theft, conceal the 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. 

IMPORTANT:  Some newer cars have a plastic
safety coating on the inside of the windshield.  The
windshield bracket may leave permanent marks on
this type of surface. To find out if your vehicle has this
type of windshield, check the owner’s manual or ask
your dealer. We recommend that you do not leave
the suction cup bracket on the windshield in direct
sunlight.  If the detector is removed, this may cause
blistering of the dash in some vehicles.
