INSTALLATION
Mounting Guidelines
• Mount the unit as high as possible near the center
of the windshield.
• Do not mount unit behind wipers, ornaments,
mirrored sunscreens, etc. These obstructions have
metal surfaces which can affect radar and laser
signals and reduce critical warning time. (Tinted
glass will darken the DVR image.)
• Some windshields have an Instaclear™or
Electriclear™type coating which may affect radar.
Consult your dealer or the vehicles owner’s guide
to determine if your windshield has this coating.
• To reduce the possibility of theft, conceal your unit
when not in use.
Notice to Drivers in California and Minnesota:
State law prohibits drivers in California and Minnesota
from using suction mounts on their windshields while
operating motor vehicles. Other dashboard mounting
options should be used. (See California Vehicle Code
Section 26708(a); Minnesota Statutes 2005, Section
169.71). Check local laws for compliance.

Windshield Mounting
• Clean the selected area of the windshield for
mounting using a quality glass cleaner.
• Slide detector onto bracket until it locks in place.
• Peel plastic cover off sticky portion of suction cup.
• Press the suction cup onto the windshield.
To secure, press the locking tab toward the
windshield. Important: make sure unit is level.
• Loosen the knob on the bracket to adjust the angle
of the unit to be level with the road. Tighten knob
to secure the unit's position.
Important: Some newer cars have a plastic safety
coating on the inside of the windshield. The
windshield bracket may leave permanent marks.
Check the vehicles owner's guide or ask your dealer
before applying suction cup mount.

Power Cord Connection
• Plug the small end of the power cord into the unit’s
power port.
• Plug the large end into the vehicle’s cigarette
lighter/12V accessory socket.
NOTE: Cord fits tightly into detector. When installing
the cord, expect some resistance.
The power plug USB port can be used to charge an
ipad, iphone, smartphone, MP3 or tablet. The output
for the USB port is 1A.
Fuse Replacement
The lighter/12V accessory socket plug is equipped
with a replaceable 3 amp fuse located behind the
silver tip. To replace the fuse, carefully unscrew the tip
of the plug.
Important: Unscrew slowly. The tip contains a spring
which may fly out when disassembling. Insert the
new fuse with the spring and screw on the tip. With
