Interpreting Alerts

Although PASSPORT 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 PASSPORT 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
PASSPORT’s warning system for radar and
laser 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.

You are approaching a radar unit concealed

by a hill or an obstructed curve.

Explanation

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 characteris-

tics 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

PASSPORT begins to sound slowly, then the
rate of alert increases until the alert becomes
a solid tone. The Signal Meter ramps
accordingly.

PASSPORT emits short alerts for a few
seconds and then falls silent only to briefly
alert and fall silent again.

PASSPORT suddenly sounds a continuous
tone for the appropriate band received. All
segments in the Signal Strength Meter are lit.

A brief laser alert.

PASSPORT receives weak signals. These
signals may be a little stronger as you
pass large, roadside objects. The signals
increase in frequency.

PASSPORT alerts slowly for awhile and then
abruptly jumps to a strong alert.

Alert

PASSPORT alerts intermittently. Rate and
strength of alerts may be consistent or vary

wildly.

PASSPORT alerts intermittently. Rate and
strength of signal increases with each alert.

PASSPORT gives an X-band alert
intermittently.
