reassembly notes (Nellcor)
The J2 connector halves are keyed to prevent incorrect connection. However, to facilitate
the connection, align the red line on the edge of the ribbon cable with pin 1 of the
connector on the SpO

board.
Grip with pliers here, and separate the J1 connector
halves. Never pull directly on the cable itself.
Note
When replacing the Nellcor SpO2 board, be sure that the DIP switch is set as
follows:
1-ON 2-ON 3-OFF 4-OFF
