E4407B Memory Battery

I'm looking to replace my nearly ten year old memory battery in my E4407B.  It hasn't failed yet but I want to replace it before it does - Preferably without causing any harm such as wiping out cal constants, etc.  I have a service guide (p/n E4401-90056) which on page 4-15 says "If you wish to replace the battery yourself, refer to the "BT1 Battery" replacement procedure in Chapter 7".    Unfortunately the manual only goes to chapter 6.  Not sure if a later version of the manual included chapter 7 or not as my manual shows a 1999 print date. 

Looks like it will pull right out of a socket and I can put a new one in but I would really like to know if there is anything more to it such as needing to restore anything after the battery is replaced, or if there is a way to do it without memory loss, etc.  I already have the replacement part on order but would appreciate any help as to the replacement procedure.

Thanks in advance,
