Although the XR70 has a comprehensive
warning system and this handbook is as
complete as we can make it, only
experience will teach you what to expect
from your XR70 and how to interpret what
it tells you. The specific type of radar being
used, the type of transmission (continuous or
instant-on) and the location of the radar
source affect the radar alerts you receive.
The following examples will give you
an introduction to understanding the XR70’s
warning system for radar, laser and safety
alerts.
EExxppllaannaattiioonn
You are approaching a continuous radar
source aimed in your direction.
An instant-on radar source is being used
ahead of you and out of your view.
An instant-on radar source or laser source is
being used nearby. This kind of alert
requires immediate attention!
Laser is being used in the area. Because laser
is inherently difficult to detect, any laser
alert may indicate a source very close by.
A moving patrol car with continuous radar is
overtaking you from behind. Because these
signals are reflected (reflections are
increased by large objects), they may or may
not eventually melt into a solid point even
when the patrol car is directly behind you.
AAlleerrtt
The XR70 begins to sound slowly, then the
rate of alert increases. The Signal Meter
ramps accordingly.
XR70 emits short alerts for a few seconds
and then falls silent only to briefly alert and
fall silent again.
XR70 suddenly sounds a continuous tone for
the appropriate band received. All segments
in the Signal Strength Meter are lit.
A brief laser alert.
XR70 receives weak signals. These signals
may be a little stronger as you pass large,
roadside objects. The signals increase in
frequency.

EExxppllaannaattiioonn
You are approaching a radar unit concealed
by a hill or an obstructed curve.
A patrol car is traveling in front of you with
a radar source aimed forward. Because
signals are sometimes reflected off of large
objects and sometimes not, the alerts may
seem inconsistent.
A patrol car is approaching from the other
direction, sampling traffic with instant-on
radar. Such alerts should be taken seriously.
You are driving through an area populated
with radar motion sensors (door openers,
etc.). Since these transmitters are usually
contained inside buildings or aimed toward
OR away from you, they are typically not as
strong or lasting as a real radar encounter.
CAUTION: Since the characteristics of
these alerts may be similar to some of the
preceding examples, overconfidence in an
unfamiliar area can be dangerous. Likewise,
if an alert in a commonly traveled area is
suddenly stronger or on a different band
than usual, speed radar may be set up
nearby.
AAlleerrtt
XR70 alerts slowly for a while and then
abruptly jumps to a strong alert.
XR70 alerts intermittently. Rate and strength
of alerts may be inconsistent or vary wildly.
XR70 alerts intermittently. Rate and strength
of signal increases with each alert.
XR70 gives an K-band alert intermittently.
