I'd like to clean the contacts, and not sure how to open it. I found
online some sites that sell this model for around $50, which I am not
going to pay. Either I clean the one I have, or send the wife to change
channels. she needs to move (just kidding, she is pregnant, I will not
be mean to her

I think you have to pry it opn in the right way, i tried with some
toothpicks but it didn't work. I imagine it is similar to opening in
iPod, which I did by the way.
thanks
