Interpreting Alerts
Although the Pro300 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
Pro300 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
Pro300’s warning system for radar, laser and
safety alerts.
Explanation
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.
Alert
The Pro300 begins to sound slowly, then the
rate of alert increases. The Signal Meter ramps
accordingly.
Pro300 emits short alerts for a few seconds
and then falls silent only to briefly alert and
fall silent again.
Pro300 suddenly sounds a continuous
tone for the appropriate band received. All
segments in the Signal Strength Meter are lit.
A brief laser alert.
Pro300 receives weak signals. These signals
may be a little stronger as you pass large,
roadside objects. The signals increase in
frequency.

Explanation
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,
burglar alarms, 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.
Alert
Pro300 alerts slowly for a while and then
abruptly jumps to a strong alert.
Pro300 alerts intermittently. Rate and strength
of alerts may be consistent or vary wildly.
Pro300 alerts intermittently. Rate and strength
of signal increases with each alert.
Pro300 gives an X-band, or K-band alert
intermittently.
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.
