You can't do it on the remote, it needs to be done using the buttons on the front of the box.
The following instructions from Toto should do the job.
Q: I've set my V+ output to HDMI or Component, but I don't have an HDTV and now I can't see any pictures
A: Hold in the Stop and Play/Pause buttons on the front panel, and press Reset. Keep Stop and Play/Pause held in until the display says 'boot'.
After a few seconds the display should say 'outpt'. Press the Fast Forward button several times until the display says 'Sd', then press OK. Wait for the V+ to reboot then you should be back in SCART mode.
