Your Detector
Display Timeout Mode
•
Your detector has a Display Timeout mode to prolong the life of your screen. Touch any button to exit Display Timeout and recall the Standby screen.
The factory default is for Display Timeout to engage from the Standby screen after 30 seconds. You can change the time interval or deactivate Display Timeout in programming mode (see page 10).
NOTE
In Display Timeout mode, the display will show a small dot moving slowly back and forth to indicate the unit is turned on.
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 programming mode (see page 11).
You can toggle between Highway and City modes by pressing the Citybutton.

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