On impulse (again!) I bought  Beocord 1500 De Luxe on eBay.  It's in great cosmetic condition, and it came with an old tape which plays fine, so I know playback works, but I can't get it to record.

There is a manual here on the Beoworld product page but that's for Beocord 1500 (not De Luxe) and there are some small differences.  Also, the manual is not exactly the best when it comes to describing how to actually use the thing.

I've tried to record by holding down one or both of the record buttons, then pushing the lever into the play position.  The tape turns, but the level meters do nothing.  I rewind and play, and the previous recording is still on the tape - nothing has recorded; it hasn't even blanked the tape.

There's an extra button on the De Luxe too which isn't mentioned in the manual - just above the tape head cover there is a button that indicates '2' of left out, '4' if pushed in.  The only thing I've found is that playback sound is muted if I push it in.

Does anyone happen to have the correct manual fior this model, or have any idea how to make it actually record!
