50g

Well I just took out 1 of the AAA batteries (it was turned off when I 
took it out) and then I put it back in because I was look at the 
battery label. When I turned it on, the font was back to default (it 
was larger than then font I used previously) and the KEYTIME was put on 
default again so that every time I pressed a key really fast: 55, only 
one 5 would show up..

So I don't know why it reset, should I take out the batteries again and 
see if it does it again?-- Okay I've taken all of the batteries out 
this time and put them back in and my memory doesn't restart anymore. 

However, my analog clock in the top right hand corner keeps on flashing 
like the connection isn't right or something. =/
