I appreciate the opportunity to participate as a member of this forum and I wish to ask a question about my HP38E that does not work in the " end" option for financial calculation . By placing the key in this option completely off the calculator .
In the " begin" option everything works , including a test run gives ok .
thank you very much

Hi Jorge,

you may check the physical condition of the contacts of the begin/end-switch on the PCB. Because it's a mechanical switch, there may be some abrasion and/or some dirt prohibiting the correct contact.

Best regards
