The functions of each status LED are explained in the table below.
LEDs are disabled in normal operating mode in order to save power thus increasing battery
lifetime. By pressing PL1 button (see picture above for PL1 position) they can be enabled for
some minutes: this feature is required to monitor the system during initial setup or
troubleshooting.
