2. Disconnect the electrical supply of SMART system and check
that all the red Leds as well as the display are off.
3. Remove the SMART terminal from its support bracket.
4. Disconnect all the connectors from the rear side of terminal,
tacking note of their respective positions.
5. Unscrew the 4 locking screws and remove the rear cover

6. Using the IC extractor, remove with care the Integrated Circuit
from the socket located on the right top corner of PCB (Fig. 2).
7. Place the Integrated Circuit, containing the new software
version, over the socket paying attention to its correct
orientation (Fig. 3).
8. Applying a moderate and progressive pressure with both
thumbs, push the integrated circuit down into the socket
(Fig. 4).
9. Reassembly the rear cover and lock it using the 4 locking
screws.
