I wonder if anyone else has come across this problem? Frequently, after inserting freshly charged batteries into my R09, it won't switch on. It took quite a while to work out why this was the first time, but eventually narrowed it down to the two copper (?) lugs on the battery door. I gave these a light scratch with a craft knife, and it turns on fine. I have subsequently tried cleaning the batteries but this doesn't make a difference. The surface area of the lugs is very small and it seems that they are prone to oxidation. I have realised that if I keep cleaning them this way, they will eventually wear out.
Can anyone suggest an alterntive? I was wondering if isopropyl & a cotton bud would work, or if there is some other sort of contact cleaner that is effective. I have not seen any mention of this problem anywhere else, but I'm sure it can't be that uncommon?
