2. Locate the correct software image (xxx.dl) for the
terminal and place it in the TFTP server directory.

4. Reconfigure the PC LAN interface to use the static
address 192.168.0.2/255.255.255.0.
5. Power off the terminal.
6. Connect the PC LAN Interface to the terminal.
7. Press and hold down the Reset button.
8. Keep the Reset button pressed while powering on
the terminal, and through the next step.
9. Monitor the TFTP server window. When the
upload starts you can release the Reset button.

up using the new image.
