jumper block description

[mooseandpebs]

Where is the jumper block description for the jumpers above the PV/Battery input block on a classic. I can't find the description in the manual. All I see are GFP and AUX description.
I am trying to figure out which jumper is the unlock jumper.

This may help.  It is on the set of 4 jumpers behind the blue terminal block. I believe it is labeled as LOK
