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 radar alerts you
receive are affected by the specific type of
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.
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
PASSPORT'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.
You are approaching a radar unit concealed
by a hill or an obstructed curve.
