Instant-on alert
When an instant-on monitoring signal is detected, the
instant-on audio alert is activated for about three seconds
and the display shows X-, K-, or Ka-band alerts.
An “instant-on” alert signal is not another radar band;
it is a means by which an officer triggers the radar gun
on and off in usually less than two seconds. Instant-on
radar signals are often used by officers in combination
with VG-2 signals.
Safety Warning Systems (SWS
™
)
When a safety radar signal is detected the safety audio alert is
activated for about three seconds and the display shows any
of the following five different safety warnings:
ROADWORK
ZONE ADVISORY
WEATHER HAZARD
TRAVEL INFO
VEHICLE WARNING
Safety Warning Systems are transmitters used by emergency
services and work crews to alert drivers to many different
emergency or hazardous conditions in the area. Presently,
there are a few safety radar transmitters in use, and these
alerts should be infrequent. As SWS
™
transmitters increase
by governmental agencies, expect more frequent safety alerts
from your SENSORO ALPHA/ALPHA+.
