Auto / Highway / City Switch
The City button selects
Passport’s sensitivity
mode. We recommend the Auto
(AutoSensitivity) mode for most driving.
Passport’s AutoSensitivity mode
provides long-range warning, with
minimum false alarms. In this mode,
Passport’s internal computer continuously
analyzes all incoming signals and
intelligently adjusts the sensitivity circuits.
You can also select conventional
Highway and City modes. When driving in
urban areas where annoying X-band
intrusion alarms and door openers are
common, City mode can be engaged to
lower X-band sensitivity and reduce X-band
alerts. Full sensitivity is maintained on all
other bands. You can customize Passport’s
City mode sensitivity. See the EZProgramming
section for details.
