Title: R09 not switching on
Post by: youngsbest on March 23, 2009, 05:02:42 PM

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?

Never had this problem myself, or seen anyone else post about it.  Do you live in a really humid area, or store the recorder in a humid place in your house?

Live in London, but the Edirol is kept in a warm room.  Maybe storing it with or without batteries would make a difference?

That's odd, really unheard off  :hmmm:

Did you have a bad battery that leaked?  It doesn't seem like you would be getting corrosion caused by internal condensation.
