• 107189, SRV KIT, SURETEMP CABLE
NOTE
Reassembly is the reverse of disassembly; however, note the following:
• The SureTemp board rests in two notches on the front housing. Place the module in the notch
near the bottom of the front housing, and the module will align with the notch near the main
PCA board.
• Ensure that you push the cable down into the rubber gasket.
• The SureTemp module will sit loosely in place until you insert the probe well.
Remove the Nonin SpO2 board
Remove the 2 Phillips screws (with washers) that attach the SpO2 board to the SpO2 adapter
board, and then lift the board up to remove.
