Fun with HP41 users/owners

[Krauts In Space]

Okay, here's another one. Mainly fun with unauthorized curious persons.
Perhaps (probably?) it's all wellknown.

If you're not in the office but don't want let your colleagues play with your HP41

LBL 'OFFF
SF11
LBL 00
OFF
SF 11
GTO 00
RTN

After XEQing 'OFFF screen goes blank.

Everytime I press ON the calculator instantly goes OFF

I first wanted to turn off sound with CF 26, but that's set with every ON keypress.
A positive side effect is that it gives the impression of some sort of malfunctioning (at least to these who are new to HP).
One beep, and (s)he doesn't touch it again. Better than all "Touch it and you're dead!" post-its *g*
It also can be a sort of alert when you can't have your eyes at your little gem ^^

"Repairing" is easy. Hold R/S when pressing on.
