What does VG2 mean - XRS 9330 Radar Detector

The VG-2 button is to engage VG-2 Cloaking Technology.
From what I can see VG-2 Cloaking Technology is a way the detector has of avoiding being detected by authorities in areas where the use of radar detectors is prohibited. I am not in a position to say how effective this is, I suggest you refer to reviews. I have only researched the meaning of VG-2.
Rider here: Please do your own research on the effectiveness of this technology on this - or any - detector.
Of course the best way to avoid being picked up for speeding is not to speed. (But you knew that..)

This is a retrace blanking problem. Probably, the Vg2 voltage is too high, so the cut-off point from the picture tube is not correct. Try to lower this voltage. On most common flyback trafo's it is the lower adjusting screw (plastic kind of button) which is used to set the Vg2 voltage. Turn it a bit CCW until the white lines disappear.

VG-2 is a device that the police use to tell if you have a radar detector turned on. This is used in VA and Washington DC as these areas radar detectors are illegal to use. If you do not live in these areas there is no reason to turn this feature on.

Have you tried the company website for their manual?

It will only alarm VG_2 when you have turned on this feature otherwise it will not. Not sure what you mean by "spec" however. From the manual "

DARK/VG-2 Button - Reduces illumination of display

to "dim" or "dark" settings. Press and hold (for two seconds)

to engage or disengage VG-2."

Have you tried this unit in a differnt vehicle? Does it still alarm the same? contact Whistler at 800-531-0004 and they can go through more options with you on steps to try and resolve this issue for you.

See my previous post

Ku is a band of radar used in some places by law enforcement. It is not used everywhere and can be a pain if it goes off for no reason. I recommend consulting your manual and turning the Ku band off if it is not used in the area in which you live. This will enable your detector to become more reliable for when you are being "zapped" by law enforcement

Pop is a way of using radar where the officer turns his radar on and off quickly. As a car approaches, they will turn the radar on long enough to get a speed reading, then immediately turn it back off to avoid detection by civilian radar devices. Some of the newer models of radar detectors have a feature which detects pop radar.

Every electronic device emits a frequency. Vg2 is what law enforcement use in states where radar detectors are illegal to identify whether a car is using a radar detector. The newer version of vg2 is called spectre and accomplishes the same thing. Some radar detectors can pick up on vg2 and spectre so the owner can turn the detector off before they are detected by law enforcement.

rick12, Vg2 is a detector used by law enforcement to detect your detector.lol I hope thats not too confusing. Basically, what it does is sniff out your detector after it goes off. If your detector "smells" the VG2 searching, your unit shuts down so as to not put out a signal to alert it(vg2) Kind of like a stealth mode,,
Here's a report on some of the popular ones;

I hope this was what you were looking for, let us know, Mechanic

When "X" lights up, this means that your RD is either detecting X band police radar or that it is detecting an X band microwave automatic door opener.

When "K" lights up, this means the same as above except that the radar signal is a K band radar signal.

When "Ka" lights up, then this means that your RD is detecting police Ka band radar since no automatic door openers operate on Ka band.

When "VG-2" lights up, this is supposed to mean that your RD is detecting a VG-2 radar detector detector (RDD). Police use RDDs such as the VG2 and the Spectre to indicate that a motorist is using a radar detector.
