The device cannot be switched on/it is diffcult or impossible to press the switch.

Somtimes the switch moves on its axis and rests against the front panel of the device. As a remedy:
- remove cover cap of the switch carefully
- softly dissolve the nut with wrench
- pull the switch for about 3 mm off the front panel and fix the nut again in this postion
