Note
Replacing the SIM card and PIN
When changing the SIM card, do not forget to change the PIN in your control.
If you are using a lot of SIM cards, it may make sense to set all SIM cards, e.g. with one cellular
phone to the same PIN.
The device also operates with SIM cards, where the PIN prompt is deactivated. In this case,
when establishing a connection, the prompt to enter a PIN is skipped.

Restoring the factory settings
If you press the SET key for longer than 4 seconds until the LED "CONNECT" lights up, then
the MODEM MD720 configuration is reset to the default values set in the factory.
