IS it possible to replace the battery without loosing the calibration
parameters?
Or do you have to recalibrate the scope after the battery replacement?

Finally I found the battery. It was buried underneath the metal
housing holding the GPIB board next to the CRT neck shield. It
supplies power to the extended memory (26k) which is part of the GPIB
interface. I noticed that the memories on the GPIB daughter board
retained a little voltage when turned off and that their was a diode
in the supply trace. Followed this to a 4 pin connector which led me
to the battery. PROBLEM SOLVED!!

Thanks to all who commented and helped me solve this problem.

somone else looks through the Google Groups archives later on?

It was a Panosonic Lithim Battery BR-2/3A 3V with solder tabs.
