It is not absolutely necessary, but if you wish, you can also update the software on the Cel-Fi to the latest version:
Then press the ‘Connect to CU’ button. You should be presented with these options:
Select the option ‘SW Version: 700N029-002-025’ and press the ‘Go’ button.
The configuration update takes up to 5 minutes; after that the WU will reset and when it comes back up:
- The coverage bars on the WU should be illuminated to indicate the 3G coverage for the selected network operator.
- The CU should display a number (or E1 if there is no 3G coverage at the WU).
That's it! You are all done!!
