I have rather an old ansaphone (works fine though) that prefaces each message played back with "Batteries low - please replace batteries". The reason is there are no batteries in there - because they only last a few months so I don't bother.
It'd be nice if I could get rid of that irritating message. What are the grps thoughts on how to do this? I thought maybe soldering a resisitor of appropriate value (say a few 10's of ohms) across the battery input terminals - to pretend to be the internal resistance of the batteries if they were there. 2nd idea was to jumper the +/- from the powers supply brick (9vdc) to the battery connector.
I'd like some feedback on these ideas before I try it :-) Thanks
