HP 38E - Jorge Tucakov - 03-06-2014 04:34 PM 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 RE: HP 38E - Karl-Ludwig Butte - 03-10-2014 07:54 AM 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 Karl |
