For the door-bell connection close lever on switch C, and put G up
so that D and E do not come in contact. If anyone is ill and you
do not want the bell to ring, open switch C.
The wiring for this device may all be on the back of the board.
The switch and levers are fastened with small screw bolts, which
allows wiring at the back.
