IntelliShield Highway/City Modes
•
Your detector is equipped with IntelliShield false signal rejection technology
which consists of a Highway mode and three different levels of City modes:
City X, City X Beep Off and City X+K.
Highway mode provides full response to all signals detected. The City modes
reduce false alerts while you are driving in or near urban areas where there
are many sources for conflicting X or K band signals such as microwave
towers and automatic door openers. The factory setting is Highway. The
factory City mode default setting is City X; it can be changed in Menu mode
(see page 12).
You can toggle between Highway and City modes by pressing the City
button.
NOTE
When you change to City mode, the unit will enter
whichever city default mode is set at the time.
