I know this is a bit off-topic but would you be kind enough as to elaborate on this?

Thanks

What does it mean "do not trust in a calculator"? Something like this: I stored approx 50-70 equations in my 35S - not a big amount I know it. Mainly equations for my job and 4-5 programs to calculate something little complicated than a simple equation (for example settling velocity of particles, orifice sizing, fitting characteristics curves for blowers data from catalogs, etc...).

During a battery change all of them are lost.
That's all.

FYI: That was NOT MY FAULT. Since then my 35S sits in a shoe box - but it seems to me I'll never forgive it.
