4. SENSOR REMOVAL AND REPLACEMENT

The OM-25ME is shipped with a new MAX-250E oxygen sensor installed.

Although the sensor has a very long expected life, eventually the sensor

will require replacement. Removing or installing a sensor, when

necessary, is a very simple procedure. To remove and install a new

sensor:

1) Grasp the sensor in one hand and, with the other hand, unscrew the

cable connector counter-clockwise at the sensor.

2) Pull out the cable connector plug from the expired sensor.

3) Unscrew the flow diverter from the sensor and discard the expired

sensor.

Note: The sensor contains lead and lead acetate, be sure to dispose

of expired sensors in accordance with hospital, local, state and

federal regulations.

4) Remove the new sensor from the packaging and remove the

protective film from the sensor face.

5) Insert the cable connector plug into the receptacle of the new sensor

and tighten the cable connector.

6) Screw the flow diverter onto the new sensor.

7) Wait approximately 20 minutes for the sensor to reach equilibrium.

8) Calibrate the new sensor.

Note: If the monitor is on when the sensor is detached and replaced,

the monitor will automatically force a re-calibration. The display will

read “CAL”.
