HP 21 with Key Detection Error - Matthias D. - 11-21-2017 05:48 PM
HP-Friends!
Played around with my HP21 (Woodstock), pressing the keys very gently to see how much pressure is necessary. Most keys worked normal, but when I pressed the 5 a little bit and a few seconds a 7 appeared. It was reproducible with that key. Didn‘t expect this! Can anybody explain?
Thank You!
