detected, the band ID and signal strength are displayed.
The audio alert is continuous and has a Geiger counter-like
pattern. The faster the beep, the closer or stronger the radar
source.

Laser Audio/Visual Alerts

When a laser signal is detected the word "LSR" and the
corresponding laser pulse rate is displayed, the audio alert is
continuous for a minimum of 3 seconds. "LSR 238"

Pulse Protection

®
Pulse (or instant-on) radar is more of a threat 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 shows:
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.
