The following step is only necessary if you want to test the connection to the myDatanet server afterwards.
5. Connect the antenna (see Connecting the mobile network antenna). The antenna is not included in the scope of delivery and must be ordered separately.
6. Reinsert the cover of the SIM slot and the power supply unit.
The following step is not mandatory.
7. Check whether the connection to the myDatanet server has worked correctly (see Testing communication with the device).
8. Close the housing cover. The best option is to tighten the four screws crosswise (torque: 0,5 Nm; At the first screw 0,7 Nm because the threads have to be shaped into the base part first.) so that the housing cover is positioned evenly.
   Important: Ensure that the seals are clean and intact before closing the housing cover. Remove any impurities and/or dirt. The manufacturer shall not be liable for any damage to the device caused by leaky or faulty seals.
9. Check that the housing cover is positioned correctly on all sides and that no foreign materials have been trapped between the housing and housing cover.
