INTRODUCTION

Your Road Patrol XK Wireless Hidden Remote Radar Detector is a state-of-the
art device with five times the range of standard detectors.  It receives
both X and K-band radar signals and works with all police radar, including
the handheld type.

FEATURES

    Bumper-Mounted Sensor Unit - provides unobstructed detection of radar
                                 signals.

       Wireless Indicator Unit - Slips into a shirt pocket, and is powered
                                 by rechargeable nickel-cadmium batteries.

   Rechargeable Nickel-Cadmium - let you power the indicator unit without
   Batteries                     cords.

        Battery-Saving Circuit - reminds you to turn off your radar
                                 detector's indicator unit when you turn
                                 off your car engine.

NOTE:  Some states and localities regulate the use of radar detectors.  It
       is your responsibility to check local regulations before using your
       radar detector.

RADAR DETECTION

Police radar operates on a scientific principle called the Doppler Effect.
When the transmitted microwave radar beam strikes a moving automobile, part
of the beam is reflected back to the police radar unit.  The police radar
unit electronically compares the reflected beam to the transmitted beam.
Then, it shows a digital display of the vehicle's speed.  This complex
process requires less than a second to complete.

Your radar detector's ability to recognize police radar signals is based on
two factors, selectivity and sensitivity.

Selectivity is a measure of your radar detector's ability to reject false
signals.  Sensitivity is a measure of its ability to detect very weak
police radar signals.

Your radar detector has high-level selectivity and sensitivity, owing to
modern superheterodyne technology.  Earlier radar detectors had to receive
a direct beam in order to register the presence of police radar.

Your Micronta Wireless Hidden Remote Detector's up-to-date superheterodyne
technology is sensitive to both direct and indirect radar beams, and can
detect very weak police radar signals.

RANGE

The maximum operating range of the best police radar is about 2500 feet for
automobiles and 3500 feet for large trucks. The effective working distance,
however, is somewhat less.  This is the distance within which a target
vehicle will reflect the police radar signal strongly enough to activate
its digital display.  For stationary police radar, the effective working
distance does not exceed 1500 feet.  Moving radar has an effective working
distance of up to 2000 feet.

Although radar signals cannot work effectively beyond 2000 feet, the
signals can travel much farther.  Police radar signals widen in a cone
shaped pattern as they move away from their source.  Any portion of a radar
signal that travels beyond the effective working distance is called scatter
Scatter can be detected several miles from the originating radar unit.


RADAR EFFICIENCY

Police radar is highly accurate (to one-tenth of a mile per hour), but
there are several things that can affect its accuracy.

Radar signals can travel only in straight lines.  Because of this, they are
effective only in line-of-sight situations.

The reflected signal is much weaker than the transmitted signal.  The
transmitted signal can reach as far as five miles. However, the approaching
target vehicle must be close enough to reflect the signal with sufficient
strength to activate the police radar unit.

Besides making a radar measurement, a police officer must be able to make a
visual identification of the target vehicle in order to issue a valid
citation.  Beyond 1700 feet, visual accuracy is questionable. Hence, police
use of radar may be effectively limited to 1700 feet.

These principles are illustrated in the following examples:

Radar does not detect Vehicle A (outside the effective working distance) or
Vehicle B (out of the line-of-sight).

Radar detects Vehicle A (entering the effective working distance), but does
not detect Vehicle B (still out of the line-of-sight).

Radar displays an incorrect speed measurement (always lower than the actual
speed) when the target vehicle reflects the radar signal at a wide angle.

A vehicle traveling at a 90-degree angle to the radar beam registers a
speed of zero.

RADAR TIPS

The False Alert Suppression Technology (FAST) circuit in your radar
detector filters out most of the extraneous signals from other radar
detectors on the road.  This circuit does not reduce your detector's
ability to receive actual radar signals.

Because of the high sensitivity of your radar detector, it can detect
energy from devices operating on the same frequencies as police radar
(door openers, railroad-car counting devices, and security systems).  It's
impossible for your radar detector to distinguish between police radar and
other signals transmitted on the same frequencies.

Not every police car you see is equipped with radar.  Not all radar
equipped police cars operate their radar units all the time.  Do not expect
your radar detector to sound an alarm every time you see a police car.

Your radar detector might occasionally give you a late alert.  This is
because radar signals are highly directional, and the way the officer holds
a radar gun can affect your detector's response.  The way the radar is
turned on and off can also affect your detector's reaction.

Your radar detector is a driving aid, not a license to speed.  Use it with
common sense.
