The workaround for the "Cal Signal Not Found" error is covered in the Assembly Level Repair manual.

If you had to reload all the correction constants, I would start with the "Analyzer Initialization" section in that manual (namely: setting DEFAULT CONFIG) and go from there, if you haven't already done so.

After replacing battery I entered the Time Base Correction, Frequency Response Correction & Step Attenuator Corrections.
Now when I go to perform Cal Freq or Cal Amptd I’m getting a Cal Signal Not Found.
I checked the CAL OUT and I’m seeing 300.000824MHz -20dBm on my Spectrum Analyzer.
Input using an HP E4432B Signal Generator set 300MHz -20dBm I’m seeing 300.8MHz at -28dBm.
As I change the Span I get different frequency’s showing?
