Hi All,
I have acquired a HT20 South Carolina built HT20 I must move very soon. It has been in a tool room infrequently used. I don't get documentation with it so making sure I don't lose memory, parameters etc is imperative. The control fires up fine now.

Problem is I will have to store it in a warehouse for about 9 months before I can move it in, so I think I absolutely must replace ALL of the backup batteries in the control before moving it so as not to risk losing anything.

I found the big d-cell, pack easy enough to replace with the machine on. But from I can get from the web there may be batteries on each servo drive, on the motherboard and who knows where else.

Can anyone tell me where the various batteries are located on this Fanuc 10Te-F? Can they also be changed with the power on at no risk of data loss? Sorry for the dumb questions on such an old piece but I am very new to this, it is my first CNC lathe and first Fanuc.

TIA,
Bill
