What is the “ext.” / “int.” switch on the Truma iNet Box for?
The switch controls whether the iNet Box sends signals via the internal or external aerial. If an external aerial is connected to the iNet Box, the switch must be set to “ext.”. The internal aerial is then switched off.
Remember that reception could become worse if you connect a wrong aerial to the Truma iNet Box. Contact your Truma Partner if you decide to connect an external aerial and pay attention to the specification in the operating instructions.
