Re: HP 21 - How to troubleshoot? Message #4 Posted by Adam Vaughn on 30 Sept 2013, 11:14 p.m., in response to message #3 by Geoff Quickfall
Thanks for the responses. I have heard further from the seller, and received two photos of the calculator in operation. In the 'before' picture, '8's can be seen flickering across the display. After powering it using two 1.2V rechargeable batteries taped together, the display shows what looks to be a normal set of digits. Does this mean I'm in the clear, or could there still be something wrong? I can post the photos, if necessary. Once again, thanks!
