Hi martz...not too sure if this receiver can be patched...follow this link and post your original question...you will probably have to register but its worth it if you can patch as there are regular patches for other comag receivers here.
Edited:
Just read the link you posted and it looks like the SL35 is patchable with the SL65 patch..if this is the case you will find all the info you need on the forum I linked
