• The Traffic Advisor
™
is a stationary mode radar and is not
intended to be used in a moving vehicle.
• The Traffic Advisor
™
radar tracks the strongest signal. It
displays the speed of the vehicle with the strongest radar
return, which is typically the closest vehicle.
• The Traffic Advisor
™
measures vehicles that are approaching
and receding from the stationary radar position. It does not
discriminate the direction of the moving vehicle.
B U T T O N

• Quickly TAP (press and release)
the ORANGE button to take a single
measurement snapshot of a vehicle speed.
The displayed speed will remain visible for
30 seconds.
• Press and HOLD the ORANGE button
to continuously measure the changing
speed of a vehicle as it accelerates or
decelerates. The Traffic Advisor
™
radar will
update the displayed speed approximately
every 3/4 of a second as long as you
continue to HOLD the ORANGE button
down.
• TAP the small black RECALL button to
review the tracking history of the previous
10 recorded speeds.

measurement, press both
buttons at the same time,
and then let go. The
currently selected units
indicator will blink.
S T E P T W O
Press the ORANGE

C A R
FROM 1/2 MILE (0.8 KILOMETERS)
M O T O R C Y C L E
FROM 1/4 MILE (0.4 KILOMETERS)
Radar technology works by sending a signal out to an
object, and then measuring the reflected signal that
bounces back. The larger the object, the greater the
reflected signal and therefore the longer the range.
The Traffic Advisor
™
will accurately measure the speed
of a car from 1/2 mile (0.8 kilometers) away, and a
motorcycle from 1/4 mile (0.4 kilometers) away.
