4.3 Start-up procedure
1. Press and hold the ON/OFF button to turn the terminal on and off. After holding
down this key for a few seconds, the indicator lights up your Terminal, proceeding to boot
it.
2. If the terminal requests a PIN code, enter the 4-digit code (by default, the preset code is
0000), which appears on the screen as ****, and press OK. You should change this code
for a more secure code that you can remember.
3. While it is switching on, the terminal will show additional information on the display:
welcome message, version and user information.
4. There are two operating modes, network mode and direct mode. In network mode, the
terminal will be operative when it has successfully registered on the system.
