hill cannot be received until you are at or near the top.
Warning time may be minimal (as in situation #2) since a
strong signal is not present until you are near the crest of the
hill. At this point, you may be nearly in the police officer's
line of sight. When cresting a hill, a weak initial alert followed
very quickly by a full alert is typical. This alert pattern requires
prompt attention.

Moving Radar behind you, traveling in the same direction.
Police Radar signals transmitted from behind your vehicle can
be received when reflected by objects in front of you such as
large signs, bridges and trucks. As you drive, the size and con-
figuration of these objects are constantly changing causing the
strength of any reflected Radar signal received to vary. A strong,
uninterrupted alert indicates the patrol car is close behind.
Instant-On Radar
If you are the target vehicle, an alert caused by instant-on Radar
will be strong and immediate. When encountered, your unit
responds with a three second audio/visual instant-on warning.
Typical False Alert (Radar)
Ideally, a Radar detector should only alert in the presence of
police Radar. However, because other devices share X band
with police Radar, false alerts sometimes occur. Generally, a
false signal produces only a short audio and visual alert. Since
they are most often weak, it is possible to drive out of the
signal's range very quickly and receive only a brief alert.
Although many times the probable source of the false signal
can be identified (supermarket, bank, commercial building,
