33. Place the Oximeter Carrier Board on a static-free work surface so that J1 is on
the bottom left and J4 is at the bottom right.
34. Align the MSpO
2
Board over the Oximeter Carrier Board screw holes.
35. Use the washers and #4-40 x 1/4 screws provided in the kit to secure the
MSpO
2
Board to the Oximeter Carrier Board. Use the flat washer for the top
left screw; use the shoulder washers for the remaining three screws. (Refer to
Figure 12-9 .)
36. Connect the ribbon cable from J2 on the Oximeter Carrier Board to JP5 on the
MSpO
2
Board.
37. Connect the ribbon cable from J5 on the Oximeter Carrier Board to JP1 on the
MSpO
2
Board.
38. Insert the Oximeter Carrier Board into the slots labeled J9 and J13 on the Front
End Motherboard. (See Figure 12-10 .)
39. Connect the front panel MSpO
2
harness cable to J6 on the Oximeter Carrier
Board.
40. The MSpO
2
harness cable is already connected to the front panel in all 120
Series Monitors.
41. If FSpO
2
is installed in your monitor , re-connect the front panel FSpO
2
harness
cable to J1 on the FSpO
2
Board.
42. Replace the hold-down cover for the front end boards and secure with all four
screws.
43. Locate switch pack SW1 on the Main Motherboard and set switches 6 and 7 to
the OFF position. (See Figure 12-8 .) This enables the MSpO
2
and Blood
Pressure Boards to communicate with Main Motherboard.
44. Ensure that the blood pressure tubing remains routed through the notch at the
top of the DSP Board.
45. Replace the top cover and secure all nine screws.
46. Disconnect all cables from the monitor’s front panel connectors.
47. Re-connect the monitor power cord.
48. If FSpO
2
is not installed in the monitor, turn on the monitor and verify that the
NBP and MSpO
2
parameter titles display on the screen. An “empty” pulse
amplitude indicator should also appear in the MSpO
2
area. (Refer to Figure 12-
11 .)
If FSpO
2
is installed in the monitor, connect both the MSpO
2
and FSpO
2
sensors. Turn on the monitor and verify that the NBP , MSpO
2
, and FSpO
2
parameter titles display on the screen. An “empty” pulse amplitude indicator
should appear in both SpO
2
areas. (Refer to Figure 12-11 .)
49. Fill out the Update Installation Verification Form included in the kit. Be sure to
include the monitor’s serial number and catalog number on the form. Follow
the instructions to fax the form to GE.
