How to fix battery cut-out on NH1?

[trager]

Hello all. I'm new so I hope you don't mind me jumping straight in with a request for help.

I'm having the problem with my NH1 where occasionally if I, say, step too vigorously from the road to the pavement, the power cuts out completely for a moment and the player resets to its last saved settings. I notice this has been mentioned before...

...and I take it that the solution lies in cleaning the contacts in the battery compartment. As I am rather inexperienced with such things, however, I was hoping someone could give me some tips on how to go about this. (How to access, what implements/fluids etc.) I had the same problem with my N710 a couple of years ago, but on that occasion I had an extended warranty to fall back on. Not so much this time. Could anybody give me any advice?

I would appreciate all suggestions. Thank you!
