3.6 SIM card installation
You may need to insert at least one SIM card in the Regesta PRO PLC before you can use the WWAN interface.
Some countries have services (CDMA) that do not require SIM cards.
The Regesta PRO PLC has two SIM trays located inside the device casing labeled SK1 and SK2.
Where installations require only one SIM card, the card should be installed in the main SK1 tray.
Warning
Never install the SIM cards when the device is switched on.
Always disconnect the device from the main power supply before installing the SIM cards.
Always disconnect the device before removing the casing to access the trays.
Please protect yourself against electrostatic discharge (ESD) when inserting the SIM cards.
Do not touch the SIM card connectors.
You will need to open the upper casing of the device in order to access the SIM tray. To do this, undo the fourscrews
on the top panel of the Regesta PRO PLC:
