The MT 624 after removal of the PCB.
Now you have to cut the red wire that comes from somewhere under the metal belt,
and runs either to the black connector, or disappears in the cable sleeve whit the
other 4 visible wires.

P a g e 7 of 8, V1
Make sure you do not cut a second red wire that runs from the connector into the
cable sleeve. If the red wire goes to the connector, cut the red wire close to the
connector. If the red wire goes into the cable sleeve, cut the red wire where the red
wire enters the cable sleeve. This gives the maximum length for this piece of wiring.
Then enter this lose end of red wire in the clamp connector. No need to remove
insulation. Put it right in the middle and then snap together the clamp. It usually
needs no tools, just your fingers, to close the clamp.
The result should look as above.

P a g e 8 of 8, V1
Attach the connector at the end on the header in the middle of the new pc board,
and insert the pc board into the black connector. Center the contacts well and make
sure the board is inserted to its maximum position.
It should look now as above.
Now you have to adjust the 2 potentiometers that control the optical sensor
sensitivity. For instructions, please consult the “SuperbaKnit Interface A
Adjustments” document.
Place back the plastic end cover of the bed just in the reversed way as you removed
the cover, and secure the cover with the screw from the bottom side.
