Replace Sensor

Error Message: C80/REPLACE (Change Sensor/End of Sensor Life)

Cause: The maximum expected life of the Sensor has been reached. In other words, either the Monitor

has seen a problem with the Sensor, triggering two calibration alarms, one after the other, or 72

hours have passed since the Sensor was first put in and initialized. This alarm will repeat every

20 minutes until the Sensor is changed and initialized.

Action:

1. Press the SEL and then the ACT button to turn off the alarm.

2. Turn the Monitor Off.

3. Turn the Monitor On.

4. Remove the Sensor, and insert a new Sensor. Follow the Inserting the Sensor section in Chapter 2:

Getting Started. Initialize the Sensor by following the Sensor Initialization section also in Chapter 2.

NOTE -

If after changing the Sensor, but before doing the initialization, the alarm repeats, turn off

the alarm and go on with initialization.
