Hello;
This message, "Machine Reset", is intended to be harmless. In the 42S (also Saturn-based) it means nothing is lost (programs and variables). I do not know the 27S, but I don´t believe it would be different. At least in the 42S, simply pressing [ON] key restores operating condition.
Cheers.
(BTW, what procedure in the manual you're referring to?)

If you don't have anything important in memory, you might try doing a memory clear - OFF & 1/X and SQR all three keys at the same time. If that doesn't work, you can try taking out the batteries and shorting the contacts in the battery compartment together with a paper clip for a few seconds while turning the calculator on.
