[Elecraft] KBT2 Instructions for the K2 Internal Battery

[Keith Hamilton]

The KBT2 Internal Battery Installation Instructions need to be 
updated or have a errata attached. The instructions on page 8 
refer to a "S1" switch on the control board. I searched the 
archives and found out that the switch was changed to 3 pin header 
"P7" after about serial number 3000 or so.

So to prevent others from this confusion the instructions need 
changed or added to.
