Using Humax remote with Pace Sky box


Ad detector
I have an ancient Pace Sky digibox DV3 which I have been using as Freesat receiver for those channels not available on Freeview including the 24 Olympics feeds.

Does anyone know if there is code which will allow the Humax remote (RM-F04) to control the Sky box? I cant see anything in the Appendix to the HDR-FOX-T2 user manual
