Fitting an LGREM4x4.v2 expansion module
It is not necessary to turn the power off.
Correctly orientate the module as shown in the diagram and plug it onto the main board
making sure that the posts line up with the holes.
Snap it into position.

rS Restore mode
0 > restart with all relays Idle and Keyfob_state = SET (and KC_state Off)
1> restart with last known states (reload from EEPROM on power-up)
EM Extra mode
0 .. normal mode
1 .. extra mode (prints content of Learned_Keyfobs & entire EEPROM, for debug)
Value Function
---------------------------------------------------------------------------------------
00 ... no_function, relay permanently Off (=> stays Off on power-failure)
