5‑mm flat head screwdriver or Pozidriv screwdriver (PZ2)
If
you are using the Vaisala SIM card, you can skip this task. If you are using a custom SIM
card, you must insert it in EGW501. It is easiest done before installing EGW501. EGW501
requires a 2ff (mini) SIM card.
To remove the EGW501 cover, unscrew the fastening screws (4 pcs) and lift the
cover.
Use either a 5‑mm flat head screwdriver
or a Pozidriv screwdriver (PZ2).
Insert the SIM card into the highlighted SIM card slot on the right.
Put the cover back in place.
Tighten the screws until the cover makes good contact with the
surface of the enclosure base.
