Mode Alerts

Because POP

Mode radar utilizes the same

K or Ka band frequencies, POP

Mode Alerts will be

displayed as regular radar alerts.

LASER/RADAR ALERTS

Speed Radar Audio/Visual Alerts

When X, K, or Ka is detected, the band ID and
signal strength is displayed. The audio alert is
continuous and has a pattern like a geiger
counter. The faster the beep, the closer or
stronger the radar source.

Laser Audio/Visual Alerts

When a laser signal is detected, the audio alert is 
continuous for a minimum of 3 seconds. 

• The Display Shows:

Pulse Protection

®

Pulse (or instant-on) radar are 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, the
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.

MODE ALERTS

VG-2 Audio/Visual Alerts

Note: 

You must turn this feature on before it will

detect VG-2.

When a VG-2 signal is detected, the detector ‘hides’ its
own radiated signal and becomes undetectable by
the VG-2.
Every 30 seconds, the detector checks for a VG-2
signal. If a VG-2 signal is still present, the unit
continues to hide and repeats the VG-2 alert. If no
signal is detected, two beeps are provided, 
indicating an ‘all clear’ condition. During a VG-2
Alert X, K, and Ka band signals cannot be
received (Reference page 21 for VG-2 information).

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.
