OPERATION SETTINGS

City Operation

In modern cities there are many weak signals which have no relation to the

traffic signal controllers. The City mode reduces the detector's sensitivity to

weak signals and eliminates responses to false sources.

It’s important to notice that old or poorly shielded detectors in other vehicles can

sometimes transmit weak radar signals. So don’t forget to switch on the City

mode where it is necessary.

• To select the City mode, press CITY button.

• Press CITY button again to go back Highway mode

The Highway mode provides maximum sensitivity for open road driving

where there are no false signals
