In no case, do not shorten the antenna! Its length is optimal for operation within the used radio frequency range!
During installation and operation of WallSwitch, please adhere to general rules of electrical safety when using
electrical appliances, as well as the requirements of electrical safety regulations.
It is expressly forbidden to disassemble the device. Do not use the device with damaged power cables.
