2.
Disconnect the sensor from the pulse oximeter and connect it to the Nellcor Port DB9

resistance is acceptable, a "sensor-detect beep" is produced and the following message is
displayed on the LCD for as long as the sensor remains connected to the Nellcor Port:
RCAL OK! Now connect
sensor to pulse ox.

probe and commence testing .
If the detected resistance lies outside the acceptance range for Nellcor sensors, an "error beep" is
produced and the following error message is displayed as long as the sensor remains connected to

out of range!
In this case, the default Nellcor "R-Curve" will be selected when the sensor is removed from the
Nellcor Port.
An "error beep" is produced in response to the following error conditions:
