... you have a program that runs everytime you switch it on.
Both the HP42 and the HP41 have this option: set flag 11 (SF 11) and when you turn the calculator ON, the current program automatically runs. If the program is something like this:
then everytime you switch your calculator ON, flag 11 is set and the program stops. The fact is that when you switch it back OFF and later ON, the program runs automatically (flag 11 is set), executes GTO 00, sets flag 11 again and stops.
When the calculator is switched ON and flag 11 is set, the beeper produces a standard tone to remind ist state. Then flag 11 is cleared and the current program automatically starts running.
After you switch your calculator ON again, press these keys: (obs: [SHIFT] is the golden key)
If you see:
[04 GTO 00 ]then you actualy found the reason. To get rid of it:
Let us know if it changed something.
