If the LED on the charging station flashes red after installing the SILENO free, an unconnected cable of the charging module may be a possible cause.
We recommend checking this by removing the cable of the charging module once from the charging station and then replugging it, as it was/should be done when it was first put into use. Make sure that the retaining nose of the plug clips in and has a tight fit.
To remove the charging module, press against the clips from below with an Allen key.
