[Premium-Rx] E1500

?I have a most perplexing problem with my Telefunken. I choose not to use a battery backup as the original mercury
types are no longer made. Upon turn on the synthesiser does not lock until approx 10 minutes have passed, then all
is normal. If the set is then turned off it will fire up immediately even if it is left for two hours. Of course if a 5.4 volt back up
is applied everything is normal. Can anyone assist? My German is not the best and myn translation of the manual is slow 
and possibly inaccurate.
