Inserting the SIM card
Notice
•
The device must be switched off when you insert or change the SIM card.
•
A plug-in SIM card (3 V) is used.
Changing the SIM card
If you change the SIM card, please do not forget to update also the PIN number in
your application.
If you use a lot of SIM cards it can be helpful to set all PINs to the same PIN
number. You can do this i.e. by using a mobile phone. Please observe the security
requirements of your organization.
To insert the SIM card proceed as follows:
1. Make sure that the device is disconnected from the supply voltage.
2. The SINAUT MD720-3 must be opened to insert the SIM card.
The housing is fastened by two clamps, one on top of the housing and one on the
bottom side (see figure 2-1).
