If motion is detected again during the back-up time, the cycle 

will start from the beginning. 

Due to its high sensitivity, the 

DRM can act as a presence sensor.

 The accuracy of the sensor 

operation does not depend on the temperature. The detection 

range, the brightness level that activates the sensor and the time 

of operation back-up are set using the knobs described later in 

this manual. The sensor is designed for indoor use. 

The power of microwave radiation is relatively low and 

completely safe for humans and animals. Its value is 

below 10 mW. In comparison, a microwave oven and a 

mobile phone radiate with a power of approx. 1000 mW.
