OPERATION

Mode Alerts

Because POP

Mode travels on regular radar 

bandwidth, there is no particular alert for POP

Mode transmissions. POP

™ 

Mode alerts will be 

displayed as a regular radar alert.

LASER/RADAR ALERTS

Speed Radar Audio/Visual Alerts

When X, K, Ka, or Ku 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.

Note: 

Geiger not available when custom tones

are selected

Laser Audio/Visual Alerts

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

• The Displays Shows:

The more “|||”, the closer the laser source.

Pulse Protection

®

Pulse (or 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 shows:    
XTR-325 displays an

P

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.

Once VG-2 is detected, 

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’ condi-
tion. During a VG-2 Alert X, K, and Ka band sig-
nals 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.
