+**Automatic recovery when disconnected**
+When installing the GX 4G LTE in an area that you expect continuous internet coverage, you should enable the "Reboot device when no contact" option in the VRM menu of the GX device. This will automatically reboot the GX device, as well as power cycle the GX 4G LTE, when the transmission of data to VRM has failed for the configured time.
+{{:venus-os:gx_gsm.jpg?400|}}
+Note that if you are leaving internet service coverage areas (such as an RV on the move, or a boat leaving dock to go to sea) then it is recommend to disable this setting, so that your GX is not rebooting itself for no reason. Or set it, for example, to a two hour time-out. And accept a reboot every two hours when underway.
