Filter Mode
There are times when a radar detector can emit
the same frequency as police radar and can
cause your detector to falsely alarm. Sometimes
a detector can alert when picking up another
radar detector in a nearby vehicle. The Whistler
Filter Mode options provide for false alert sup-
pression from other radar detectors. Two
options exist:
Filter: Allows for normal filtering.
Filter 1: Provides and extra step to analyze the radar
that may come from other detectors.
Filter is the factory default and should provide
adequate filtering for most conditions. If you
experience excessive alerts due to radar detec-
tors in other vehicles, try the Filter 1 option.
Filter Mode functions in both Highway and City
Modes. See Option Select Mode to change
Filter settings.
