Although the RX75 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 RX75 and how to interpret what
it “tells” you. The radar alerts you receive
are affected by the specific type of radar
being used, the type of transmission
(continuous or instant-on) and the location
of the radar source.
The following examples will give you
an introduction to understanding the
RX75’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 blend into a solid tone even
when the patrol car is directly behind you.
Explanation
You are approaching a radar unit concealed
by a hill or an obstructed curve.
A patrol car is travelling 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.
CAUTION: Since the characteristics of
these alerts may be similar to some of
the preceding examples, over
confidence 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.
Alert
The RX75 begins to sound slowly, then the
rate of alert increases until the alert
becomes a solid tone. The Signal Meter
ramps accordingly.
The RX75 emits short alerts for a few
seconds and then falls silent only to briefly
alert and fall silent again.
The RX75 suddenly sounds a continuous
tone for the appropriate band received. All
segments in the Signal Strength Meter are lit.
A brief laser alert.
The RX75 receives weak signals. These
signals may be a little stronger as you pass
large, roadside objects. The signals increase
in frequency.
Alert
The RX75 alerts slowly for awhile and then
abruptly jumps to a strong alert.
The RX75 alerts intermittently. Rate and
strength of alerts may be consistent or vary
wildly.
The RX75 alerts intermittently. Rate and
strength of signal increases with each alert.
The RX75 gives an X-band alert
intermittently.
