METRONIC Digi-Scart freeview receiver universal remote code??

Hi,

Does anyone happen to know the remote code for a Metronic "Digi"-Scart Digital Receiver, model MET738

I just bought one today and also bought a universl remote so I can just have one remote for TV and MET738. TV working OK but can't find right remote code to get universal remote to operate the MET738 :(

Any help would be much appreciated...

Thank you.
