10.8 Modulation frequency mode
The "Modulation frequency mode" enables the use of several devices in the same field of view.
Each device uses several modulation frequencies to increase the range. If more than one device is
needed for an application, interferences may occur. The devices interfere with each other by using the
same modulation frequency.
With the "Modulation frequency mode", you can assign different modulation frequencies to the devices.
The modulation frequency is set in the "Modulation frequency mode":
You can choose among the following:
● three frequency sets with fixed default modulation frequencies
● one frequency set with a random choice of modulation frequencies
Test the ideal filter setting under difficult conditions:
● strong sunlight
● wet surfaces
10.8.1 Fixed modulation frequencies
The fixed frequency sets consist of three modulation frequencies which cannot be changed.

The fixed frequency sets are suited for applications with the following properties:
● fixed device position (no vehicles)
● maximum of three devices in one field of view
The noise level of the fixed modulation frequencies is lower than the one of the random modulation
frequencies (→ „10.8.2 Random modulation frequencies“).
► Use the fixed modulation frequencies by preference.
