HP-71B Cursor Chirp Message #1 Posted by aj04062 on 29 Sept 2013, 11:57 a.m. Has anyone ever had a HP-71B that chirps in sync with the cursor blinking? It is as if there is some EMI affecting the speaker.

Section 6.1. Or maybe you got the hearing aid version. Geoff Edited: 29 Sept 2013, 12:52 p.m.

Re: HP-71B Cursor Chirp Message #5 Posted by Geoff Quickfall on 29 Sept 2013, 8:30 p.m., in response to message #4 by Garth Wilson My 48's make noise, my 71 doesn't. I didn't think about a lex file but that is an option. When you type "ver" do you see any lex files? Geoff
