No they did enter the Mode S code that was given to us by our CAA.

What it asks for each time is the tail / flight ID code.
Since we do not fly commercial all I need to have there is the aircraft
registration (tail number) and the unit not to ask again for it.

Previous posters covered my question, thank you all.

I have a standard aircraft reg. number and will never need this

Thanks in advance

I beleive that is your MODE S code. I'm surprised they didn't enter it
when they installed the 330. You so a really easy way to find out what the
number is don't you?
