Low Battery Asterisk - HP10C

[John Cadick]

I just bought a 10C. It seems to work well; however, the low battery alarm asterisk is flashing almost constantly. I have put three new sets of batteries in it. The last were brand new silver oxide.

When I first installed the new batteries, the asterisk disappeared until I had done a few calculations. But then it came back with a vengeance.

In addition to replacing the batteries, I have cleaned the battery terminals in the calculator. They seem to making good contact.

I have searched the museum and the voyager series literature but haven;t found any suggestions.

Anybody have any thoughts? The serial number is 2248A11157. It is stamped USA.
