Re: 41CX loss of programs & battery removal Message #4 Posted by Raymond Del Tondo on 4 May 2005, 3:28 p.m., in response to message #1 by Chris
There's a capacitor inside the HP-41
which will protect memory for a
short time while changing batteries.
Since batteries can be changed within a few seconds,
normally no data will be lost.
However, this also is kinda RTFM;-)
AFAIK only the clock of the timer module
or the CX will have to be re-set.
Some of my HP-41s hold memory contents
for a few hours w/o batteries,
but that's not guarateed, of course.
It's always a good thing to have a
data backup on an external medium.
The card reader and the tape drive can be used
to store programs and other data.
You can even do a full backup of your HP-41
to cards or tape.
