[Elecraft] Calibration of KX3

[Mike]

Just a few questions
1. Can the calibration be done in any order?
2. I am doing Reference frequency calibration ( using my XG2), transmit bias calibration, transmit gain (using Elecraft utility) not doing KXFL3 as it was done at factory. Is there any other tests or calibration that has to be done? 
3. Under reference frequency calibration on page 31 using the automatic method I don't see it mentioned to unlock the REF CAL setting. Or for automatic does this not have to be unlocked? 
Thanks for all your time
