DIL selector switches:
COMPACT Unit, right-hand version: DIL switch 4 must be set to the ON position, the other switches must be set to the OFF position.
COMPACT Unit, left-hand version: DIL switches 1 and 4 must be set to the ON position, the other switches must be set to the OFF position.
COMPACT Top: DIL switch 3 must be set to the ON position, the other switches must be set to the OFF position.
