Re: The mechanics of math: Squeaking case of my DM42...how to fix?

I did the same thing (minus the squeak) when I received my DM42.

Re: Recharge the calculator ??? No CR2032?

CR2032 is not rechargeable, Maxell datasheet says “Never charge”. So I believe the circle board has such a certain design to prevent the cell battery from being charged. There is a rechargeable version of same voltage and size, its ML2032, with 65mAh capacity and a maximum 2mA charge and discharge ...

What Battery?

Dumb first post: I would like a replacement battery on hand. What is the battery spec.?

I scanned the online manual and didn't see it there. (That doesn't mean that it is not there, just that I didn't see it there.)
