Filtering

Many of the higher end Whistler RD have programable filtering.

I understand that filtering can reduce the amount of "falses" or extraneous non-police radar detected by RD.

For example, the XTR-695 and SE version have three levels of filtering:
Filter, Filter1 and Filter 2.

Can someone out there explain filtering better than the manual that comes with the detector in a way that I and others can understand? For example, what does each filtering level, filter out?

I am also curious if selecting a higher filtering level can increase the chance of missing real police radar?

Thanks.

Each filtering level filters out different cobra models. I'm not 100% sure on the order

Filter 1- starts out a 9-10 band cobra models
filter 2- 9 band and up.

FILTER can pick up distant radar scatter while filter 1 and filter 2 may miss it. I run FILTER most of the time because of Instant on. In very heavy traffic i go with filter 2

Filter 2 works great in the city, I get no Ka falses at all with it on.
