Calibration Overdue
INOP.
The CO
2
module should be
calibrated once a year or after 4,000
operating hours.
Do not use the CO
2
monitoring capabilities and call
for service to calibrate the CO
2
module. If CO
2
monitoring is essential to patient care, take the device
out of use.

hardware failure. Do not use the CO
2
monitoring capabilities and call
for service of the CO
