10. Select the Begin button to start 100 % O
2
sensor calibration. The system will indicate the
calibration status when the process is completed. If an error code in red (e.g., 00 00 00 10) is
displayed, see TABLE7-2, “O
2
Sensor Calibration Error Codes,” on page7-8 for
troubleshooting information.
11. After calibration, select Done to close the calibration window.
NOTE: In case of repeated calibration failures, replace the O
2
sensor and
repeat the calibration. If calibration still fails, contact Mindray Technical
Support.
NOTE: The error code can be a combination of 2 codes e.g. 00 00 00 18 is 00 00
00 10 and 00 00 00 08.
