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.
