Hi,
Yes, definitely. The FPP error is 99% because of the nvram battery failed
an lost the calibration. All other fails are likely a result of it. You can
verify it by going into the extended diagnostics and check the detailed
result of the FPP fail.
Then you'll need to replace the battery (older models) or the nvram on
newer models (or hack them for external battery).
But first you shoul try self cal and ext cal, without powering down the
scope and see if the errors go away. They should. If not, you should still
try the full calibration as desvribed in the adjustments section of the
service man.
Mandatory warning: don't run the scope without cover without external
cooling, you risk damaging the CCDmodules.

Well I guess you get what you pay for. At $50 for a 2440 should have been
a clue. So far the first 2440 I turned on has cal errors
4000 FPP fail
7000 CCD fail
8000 PA fail
all others passed
Maybe I should go through an external calibrate first?
