Patrick, I think the A5 boards without the battery have a flash memory.
U2008, a ER1400 EAROM holds the cal constants.

2465 to clean up

Hi Mac,
Again, qservice.tv is our friend. See:
>
In
case the link doesn't work, I found the listing for the 2465A A5 board which
includes a few photos. You will see the lithium battery with a yellow label.
(By the way, when I bought replacements from Mouser, the new batteries were
totally black, no yellow label.)
I also looked at the A5 for the 2465
and did not find a battery. Perhaps the repair manual theory of ops might
indicate how calibration constants are maintained when the unit is powered
down.
Thanks,
Patrick Wong AK6C

in teh scope. Unless it is buried inside a DIP on A5...I will read the
calibration procedure to see what they call out for changing ROM values and
post back if I find anything.
