The sensor is innately very sensitive. Therefore one is beyond the reach, from which it is to respond, the workspace. This is according to data sheet between 1-6 meters, which also reach all surfaces.
With the setting you should use a screwdriver and determine this same experiment. In the version only the symbols are displayed quite small, so you should it ever prove quickly lead the short and clear guidance to heart. A small translation error has crept nevertheless, should turn with ... meter probably the fuse or the light switch be meant.
In addition to the desired length of time, you can still set the initial brightness. For energy saving lamp one does well to leave the value set to maximum.
The standby power consumption is less than 1 watt, which is really good.
For me it did not work through doors, but I use the sensor in the corridor. But through the glass cover of the lamp itself it works perfectly.
Conclusion:
For a quick retrofitting these sensitive motion on microwave technology and a very low standby power consumption is a good alternative to the cheaper motion.
