Hi
Nice forum!
I have a 10b and a recently purchased 10bII.
The 10b has served me well for 14 years now, but the +, - and * buttons only work when pressed very very hard.
I thought that if I could open it I could spray some contact fluid on the contacs inside -
Question: How do I open it.
I searched for 10B service manual, and I found a some posts on this forum requesting it - I have one.
I purchased the 10bII because the other developed this error. Price in Norway about 100USD. I see that it is being discontinued - is that correct. I had all sorts of trouble getting one. And yes, teh keys are not the same quality as the 10b, though I do not have a problem with them getting stuck (yet)...
