4.3 Start-up procedure
1. Keep the button pressed to turn the terminal on and off.
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.
5. During the registration process, the
icon will flash. When the process is finished and
the terminal is ready to work on the network, the icon will be constant, the message "In
service" will appear on the screen and you will hear a characteristic tone.
6. If the terminal is configured to start up in direct mode, the main screen, displayed after
start-up, will show the
icon.
