Installation of Novametrix
SpO2Module in Narkomed 4
INSTALLATION PROCEDURE
NOTE: The following instructions apply to installation of a Novametrix pulse oximeter
module in place of an existing Nellcor module on a Narkomed 4. The location
of the pulse oximeter assembly within the monitor box is shown in Figure 1.
Typical assemblies are illustrated; there may be variations in the circuit board
arrangements and the shape of the mounting bracket. The monitor box cover
must be removed to gain access to this assembly.
1. Turn the System Power switch to
STANDBY, remove AC power from
the machine and disable the circuit
breakers.
CAUTION: Do not plug or unplug
remote display with power
applied.
2. Disconnect the following items from
the patient interface panel on the
left side of the monitor box:
-Remote Display & Datagrip cables
-Pulse Oximeter Sensor cable
-BP Cuff and BP Gauge lines
3. Remove the disposable reservoir
from its holder.
4. Remove the screws holding the
monitor box cover, and carefully lift
the cover from the monitor box.
5. Disconnect all backplane wire
harnesses and cables to the SpO2
assembly, and disconnect the
interface panel cable.
6. Loosen the two captive screws
holding the assembly to the monitor
box, and remove the assembly. On
later designs the SpO2assembly is
located next to the gas analyzer,
and the speaker is located on the
card cage assembly. See Figure 1.
NOTE: Record the serial number
and the firmware version
number of the Novametrix
module you are installing,
on the PMS form or other
service documentation. See
Figure 3.

INSTALLATION PROCEDURE (continued)
The following steps apply to the earlier
design SpO2assembly with a power PCB.
See Figure 1 and Figure 2.
7.1A Remove the four mounting screws
securing the SpO2power PCB to the
chassis and remove the PCB.
7.2A Remove the four mounting screws
securing the SpO2module to the
chassis on the captive screw side of
the chassis, and remove the module.
7.3A Install the Novametrix SpO2module
to the chassis with the hardware
supplied in the kit in the same
manner as the original module, with
the shield against the chassis and
J102 (7-pin white connector) of the
SpO2module toward the bottom of
the chassis captive screws.
7.4A Reinstall the SpO2power PCB.
7.5A Proceed to Step 8.
The following steps apply to the earlier
design SpO2assembly without the power
PCB. See Figure 1 and Figure 2.
7.1B Remove the four mounting screws
securing the SpO2module to the
chassis on the captive screw side of
the chassis, and remove the module.
7.2B Install the Novametrix SpO2module
with the hardware supplied in the kit
in the same manner as the original
module, with the shield against the
chassis and J102 (7-pin white
connector) of the SpO2module toward
the bottom of the chassis captive
screws.
7.3B Proceed to Step 8.
The following steps apply to the later design
SpO2assembly. See Figure 1 and Figure 2.
7.1C Remove the four mounting screws
securing the SpO2module to the
chassis, and remove the module.
7.2C Install the Novametrix SpO2module
to the bracket with the hardware
supplied in the kit. Position the new
module in the same manner as the
original module with J102 (7-pin
white connector) toward the chassis
plate using the four pre-drilled holes
without pems.
7.3C Proceed to Step 8.
8. Install the replacement assembly in
the same position as the original.
9. Remove the two screws securing the
oximeter sensor plate form the
machine’s interface panel and remove
the existing interface cable from the
sensor plate.
10. Install the Novametrix interface
cable supplied in the kit to the
oximeter sensor plate and reinstall
the plate to the interface panel.
Install opposite end of interface cable
into J102 of Novametrix module.
The next step applies to earlier designs only.
11. Remove the ribbon cable from
backplane J12, and install the ribbon
cable supplied in the kit from
backplane J12 to J101 on the
Novametrix module. Add a 3½ in.
grommet strip supplied in the kit on
the card cage chassis at the point
where J12 exits the backplane.

INSTALLATION PROCEDURE (continued)
12. Connect the interface panel cable,
and connect the backplane wire
harnesses and cables. (On earlier
models without the speaker
amplifier board, ensure that the
black wire is connected to the (+)
speaker terminal.)
13. Record the Novametrix module
serial number and firmware version
number on the PMS form.
14. Reinstall the monitor box cover and
connect the remote display cable,
BP cuff and BP gauge lines, and
the oximeter sensor cable at the left
side panel of the monitor box.
Replace the disposable reservoir.
15. Add the Operator’s Instruction
Manual Supplement (P/N 4114884)
to the Operator’s Instruction
binder.
16. Restore power to the machine.
17. Perform a PMS procedure on the
machine, including the Novametrix
Monitor calibration check given on
the following pages. Figure 4 shows
the front panel of the Novametrix
TB500B Sensor Simulator, with a
description of its controls.

INSTALLATION PROCEDURE (continued)
Novametrix Monitor SpO2 Calibration Check:
1. Plug the SpO2 sensor extension cable into the machine interface.
2. Disconnect the finger probe from the extension cable and attach a Novametrix
TB500B sensor simulator to the extension cable.
3. Turn the System Power switch to ON. press and hold the Selection Dial, and
simultaneously press the MONITOR and SYSTEM CONFIG keys to enter the main
service screen. Touch the MONITORS key to bring up a second column of touch keys.
4. Touch the SpO2 key on the screen.
5. Set the simulator’s Sensor Type switch to 87XX. Set the output signal to 3 and the
saturation to 82%. Turn the simulator ON and verify that the monitor’s displayed
Pulse reading is 60 ±1 BPM and the SaO2 reading is 82 ±2.
NOTE: Do not rely on the simulator’s low battery LED as an indicator of sufficient
battery power. Replace the battery with a fresh 9 volt transistor battery if
proper measured values are not obtained and the battery measures ≤8.5 VDC.
6. Adjust the simulator’s saturation setting to 100 and verify that the monitor indicates
99 ±1. Adjust the saturation to 62 and verify that the monitor indicates 62 ±2.
7. Depress the Open Test RED key and verify that the PULSE LO LED activates, a
continuous audible alarm is heard, and a NO OXI PULSE warning alarm is shown
on the central alarm display.
8. Depress both Open Test keys together and verify that the monitors SaO2 and OXI
ALARMS DISABLE indicators activate, a single audible tone is heard, and OXI SEN
DISC advisory alarm is shown on the central alarm display. Release the Open Test
keys.
9. Disconnect the simulator and re-connect the finger probe. Attach the sensor to the
operator’s finger and obtain pulse, and oxygen saturation readings. Disconnect the
sensor from the finger. Afther ten (10) seconds, the Warning message NO OXI PULSE
shall appear on the central alarm display and a continuous audible alarm shall sound.
10. Re-connect the sensor to the finger.
11. Note the pulse high and low alarm settings. After pulse and oxygen saturation
readings stabilize, raise the pulse low alarm limit above the actual pulse rate.
12. The Warning message OXI PULSE LOW shall appear on the central alarm display
and a continuous audible alarm shall sound.
13. Return the pulse low alarm to its previous settings.
14. Decrease the pulse high alarm limit below the actual pulse rate.

15. The caution message OXI PULSE HIGH shall appear on the central alarm display
and an intermittent audible alarm shall sound.
16. Return the pulse high alarm limit to its previous setting.
17. Note the SpO2 SAT high and low alarm settings. Raise the SAT low alarm limit above
the actual SpO2 level.
18. The Warning message SpO2 SAT LOW shall appear on the central alarm display and
a continuous audible alarm shall sound.
19. Return the SAT low alarm to its previous setting.
20. Decrease the SAT high alarm limit below the actual SpO2 level.
21. The caution message SpO2 SAT HIGH shall appear on the central alarm display and
an intermittent audible alarm shall sound.
22. Return the SAT high alarm to its previous setting.
