First Use - Advantech ICR-3831 Start Manual

First Use

Before applying power to the router, connect the components that you required for your
applications. You cannot operate the router without a connected antenna, inserted SIM card,
nor a connected power supply. Cross-shaped screwdriver is necessary to insert a SIM card.
If you do not have connected the main antenna during operation of the router, the router
can be damaged!
1. Antenna
Use TNC connectors to connect the antennas to the router. The main antenna is connected
to the router by screwing on the ANT connector (see the figure below). The second diversity
antenna can also be connected to the DIV connector to improve performance.
