Yesterday evening I got a problem with my 48GX.
After the prompt of a low battery message I removed the rechargeable batteries to charge them.
1) I've noticed that the annunciator of the "low battery" alarm was still on the display (without any battery inside ) and I thought : "this is due to the backup battery" (isn't it?) this morning the display was clear
2) after the carge I replaced the batteries and turned on the calculator but the only result is tho see the "low battery" annuciator on
3) I replaced the rechargeable with three new fresh cells and the problem is the same.....
Where am I wrong?
Thank's in advance
PS. I've googled without to find this issue, if it is well known behaviour that I don't know, excuse me for that
