A bit late, but for those like me with analogue TVs still occasionally in use for replaying analogue tapes or other outputs:
1) press the number button for the TV channel you want to store the preset in
2) press the small yellow button - this should bring up the legend Search (in red) Store (in green) Band UHF (in yellow)
3) press the red button, This will start a search through the old recognised UHF channels
4) the search will stop when it reaches a channel with an analogue signal (presumably now coming from a recorder or digital TV with an analogue output). It will show the preset number you chose in step 1 in white.
5) assuming this is the channel you want to tune press the small green button until the number turns green. It is now stored. If you are looking for a different channel press the red button to restart the search (back to step 4).
6) To add further presets (say from further analogue outputs), choose a different preset channel and restart the process at step 2
