Whistler XTR-420 - Manual (Page 5)

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).
See “Menu Mode” for engaging/disengaging VG-2.

detector.
