My nearest dealer is around 100 kms away and my knowledge of the French language is limited (an understatement) and the chance of them maintaining ancient equipment is pretty low I guess.
I have no way of checking at what time the machine comes to life but, I know it's after 01:00 and before 08:30.
So, I think the most effective and economic way of halting the unwanted start up is to employ a normal cheap timer and have it programmed to commence at, say, 09:00. That should do the trick.
In a way, I am sorry to have purchased the BM7000 as it was only the unit which was bought. To get it up and running I have had to buy special DIN adapter leads (4) speaker plugs with leads (2)and a Beolink 1000 compatible remote which does appear to be effective except I cannot get it to adjust balance.
I am not sure that the overall cost has been worthwhile and that maybe I should have invested in a current middle of the road amplifier.
C'est la vie.
Thanks to all who have responded - it certainly is a worldwide community.
