Could someone tell me what the keys are to carry out the self test on the 71B please.


Hi Rick, there is no specific key sequence for self-test, but HP have a section in the User Manual which tell you what to do to test the HP-71B.

I have scanned it and OCR'd and will email it to you.



There is a limited self test feature: press ON-/, 'INIT' message is displayed. Press 2 then ENDLINE and ROM checksums are tested. Be carefull with INIT sequence: 1 is for operation interruption, 2 for ROM test, and 3 for master reset (Memory lost)!
