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).

button.
NOTE
: When you change to City mode, the unit will
enter whichever city default mode is set at the time.
