Re: HP-48G IR Test Failure Message #2 Posted by BobVA on 6 July 2011, 5:51 a.m., in response to message #1 by aj04062
It's been awhile since I've done this, but as I recall you need to place a piece of white paper (or similar reflective surface) in front of the IR port (about an inch or so away) for this to work properly. Did you try that? (Or am I thinking of another calculator?)
Regards,
Bob
