Whistler XTR-420 - Manual (Page 6)

Speed Radar Audio/Visual Alerts
When X, K, or Ka band is 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.
“II” = weak signal, “IIIIII” = strong signal
“K K//K Ka a” Icon will flash for K Ka a detection
Laser Audio/Visual Alerts
When a laser signal is detected, the “V V//L L” will
be illuminated.
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.
LASER/RADAR ALERTS
Alert Priority
When two or more signals are received at the
same time, the alert priority is:
1. Laser
2. VG-2
3. Speed Radar
4. Safety Radar
Example:
If X band is alerting, then suddenly a VG-2
signal is detected, the VG-2 warning will
override the X band alert.
POP ™ MODE ALERTS
POP ™ Mode Alerts
Because POP ™ Mode radar utilizes the same
K or Ka band frequencies, POP ™ Mode Alerts will be
displayed as regular radar alerts.
