When you say press 0 and OK for 30 sec you do mean simultaneously or 0 then OK for 30 sec? I can't think how this would work when there are no batteries in, but I guess it must.
My understanding is that the idea is simply to ensure that any residual charge in capacitors is exhausted so the remote will reset it self when the batteries are replaced; works for me.
