If a change in XCell Sensor configuration is detected during the device turn-ON process:
-
The "ACCEPT?" prompt appears on the display
-
The  button accepts the sensor configuration
-
The  button rejects the sensor configuration; the device is not operational.
When an XCell sensor is replaced, the device automatically enables the sensor after the change has
been accepted. If a Series 20 sensor is replaced, it must be manually enabled (see section 3.4.3).
If the oxygen sensor was replaced, see section 3.2.3 regarding the oxygen reading display.
(10) After installation of new sensors, allow them to stabilize at least 30 minutes before calibration.
(11) Calibrate device before use.
Calibration is required after a sensor is installed; otherwise, the device will not perform as expected
and persons relying on this product for their safety could sustain serious personal injury or death.
