Agilent 54622D / Replacing backup battery

Hi,

I am about to replace the 3V lithium battery of my Mixed Signal Oscilloscope Agilent 54622D.
The oscilloscope is 7 years old and the voltage of the original battery is now down to 2.97V.
Until now I have not seen any error message about this backup battery but I want to be
ready to replace it.

The lithium battery CR2354 is soldered on the system board.
Anything I should know before I replace the battery?

After replacing the battery, setting the time (RTC) and
then performing a self-calibration "User Cal" will be enough?

Any information is greatly appreciated. Thank you in advance.

Best regards,

Paolo
