[M100] dead m102

[Russell Davis]

I know people have told these many, many times but my google-fu is 
failing me.

I found my misplaced m102 and although it was working when I put it into 
storage I for some reason forgot to remove the batteries so they 
corroded a little. i've cleaned that up but it doesn't seem to power up 
and i've forgotten all the steps to check/fix a dead m102.

can someone post what to check/do

thanks
