Pulse Protection
®
Pulse (instant-on) radar is more difficult to
detect than conventional radar because it
remains off until activated to measure the speed
of a targeted vehicle.
When a pulse type transmission is detected, your
Whistler detector sounds an urgent 3-second
audio warning and the display will show a max
signal strength level.

After the 3-second pulse alert, the standard alert
pattern continues for as long as the signal is
present.
It is important to respond promptly to a pulse
alert, since warning time may be minimal.
