[Elecraft] M1 - M4 per band quick memories

[charles at k5ua.com]

Just got my K3S yesterday and spent most of the night setting up the
menu and config selections. On Page 16 of the manual, it states that M1
- M4 can be used as "per band" memories that can be used to set up CW
and SSB frequencies for each band. Unfortunately, I can't find more
detail on this as I scan the manual. Can someone help with the procedure
to establish M1 - M4 mode specific memories with a band? 

Also, my K3S Config menu does not have a BAT MIN position. Has it been
removed from the Config Menu system? 

Lots to learn.
