How can I find the remote control code for a Thomson DTI 2300 Freeview Box?

The old Thomson remote control no longer functions and I have a URC22B-12 remote control which I am trying to programme to use with the Thomson DTI 2300 Freeview box. There should be a code to input but I have not been able to find one and my attempts with the URC in search mode have not been successful.

All the lists I have only show codes for Thomson VCR's.

I have successfully programmed the URC for a panasonic video recorder.

Also for the URC will the Thomson Freeview box come under Cable or SAT?

I should be grateful for any guidance on this matter.

Many thanks.
