After start-up, the MC52i terminal enters the net searching state. To turn off the MC52i Terminal use the AT^SMSO command, rather than disconnecting the mains adapter. This procedure lets the MC52i Terminal log off from the network and allows the software to enter a secure state and save data before disconnecting the power supply.
