ATTACH THE DATA ADAPTER 
There is a special M2M system connector located at the 
bottom of the Nokia 31 terminal. When mounting the 
terminal for modem use, this connector attaches to a 
matching connector on the data adapter.
If you plan to mount the terminal on a wall, attach the data 
adapter to the wall and then mount the terminal onto it. 
For more details on installing the Nokia 31 terminal, see

Please note that the SIM card cannot be removed from the 
Nokia 31 terminal if it is connected to the data adapter.
