CO2 Low Flow

CO2 alarm flag area, blue

alarm light, INOP alarm tone

Message may appear when the sampling line is initially connected; allow the a few seconds for the

flow to be established. Otherwise, the detected flow rate is 10 percent less than nominal; in this

case, check the sampling line for pinches or obstructions then clear any pinch or replace if

necessary.

If the message persists, contact technical support or authorized service personnel.

Check for CO2 Occlusion

CO2 alarm flag area, blue

alarm light, INOP alarm tone

Detected flow through the sampling line is less than 40 ml/min or the water trap may be full of

fluid:

• Check the sampling line for obstructions and replace it if necessary.

• Check the fluid level in the water trap and replace it if necessary.

If the message persists, contact technical support or authorized service personnel.

CO2 Out Of Range

CO2 alarm flag area, blue

alarm light, INOP alarm tone

The calculation value is greater than the upper CO2 limit. Perform readings to confirm patient’s

physiological condition.

If the message persists, contact technical support or authorized service personnel.

CO2 Sensor Faulty

CO2 alarm flag area, blue

alarm light, INOP alarm tone

CO2 bench detected a hardware or sensor error. Cycle AC mains power.

If the message persists, contact technical support or authorized service personnel.

CO2 Sensor Over Temp

CO2 alarm flag area, blue

alarm light, INOP alarm tone

The CO2 sensor is above the specified operating temperature. Confirm that the MR400 is

operating within the required environmental conditions (see Appendix A); if outside the specified

range, move the MR400 to an area that is within limits.

If the problem persists, stop all monitoring activities and contact technical support or authorized

service personnel.

CO2 Warming Up

CO2 alarm flag area, blue

alarm light, INOP alarm tone

CO2 is warming to operating temperature. Allow the process to complete, about 2 minutes.

CO2 Zero Required

CO2 alarm flag area, blue

alarm light, INOP alarm tone

Zero calibration of the CO2 module is needed; see page 7-15 for details.

Magnetic Field Too High

CO2 alarm flag area, blue

alarm light, INOP alarm tone

The gauss limit has been exceeded, and the AGENT option can no longer function. Position the

MR400 per the product labeling; see page 3-2.

HW Fail

CO2 alarm flag area, blue

alarm light, INOP alarm tone

CO2 module was not found during initialization. Cycle AC mains power.

If the message persists, contact technical support or authorized service personnel.

Low O2

AGENT alarm flag area, blue

alarm light, INOP alarm tone

The inspired O2 value has dropped below 18.0

Motor Speed Error

CO2 alarm flag area, blue

alarm light, INOP alarm

tone

The MR400 is too close to the MR magnet.

Ensure that the MR400 has been positioned correctly; see page 3-2. If the message persists, contact

technical support or authorized service personnel.
