ALTIMETER FAILURE - RATE . The altimeter has detected that the ambient pressure is
changing at a rate greater than 100 mmHg/minute. When the rate of change is back
within the 100 mmHg/minute range, disconnect and reconnect the CO
2
sensor to the
Propaq.
DEGRADED WAVEFORM, CHECK ADAPTER (UNCAL appears in the numerics
area)
. The Mainstream CO
2
adapter is obstructed or the CO
2
sensor has failed. The CO
2
waveform is displayed without range values. Replace the adapter or replace the sensor.
LACK OF WAVE, CHECK ADAPTER, SENSOR . Either the airway adapter is
obstructed or the CO
2
sensor has failed. Replace the airway adapter if it is obstructed.
The sensor must be unplugged and plugged in again.
LOW BATTERY, HEATER DISABLED (UNCAL appears in the numerics area) . The
Propaq’s battery voltage is too low. The CO
2
waveform is displayed without range
values. To continue operation, plug the ac power adapter into the Propaq.
NO MAINSTREAM SENSOR DETECTED (SRCH appears in the numerics area) . The
Mainstream CO
2
sensor has been disconnected from the Propaq after providing CO
2
values. Disconnect and reconnect the sensor to the Propaq if necessary.
NON-PROTOCOL SENSOR (UNCAL appears in the numerics area) . A CO
2
sensor has
been connected that does not match Welch Allyn’s specifications. The CO
2
waveform is
displayed without range values. Replace the sensor with a Welch Allyn CO
2
sensor.
SENSOR FAILURE, CALIBRATION ERROR . A sensor is defective or out of calibration.
The sensor will be disabled. Replace the sensor.
SENSOR FAILURE - EEPROM . The sensor has failed. Replace the sensor.
SENSOR FAILURE - HEATER . The sensor’s temperature control circuit or the Propaq’s
CO
2
circuitry has failed. Try replacing the sensor. If the message reappears, have the
Propaq serviced.
SENSOR FAILURE - MOTOR DRIVE . The sensor’s motor drive (in the sensor head)
has failed. Replace the sensor.
SENSOR TEMPERATURE TOO HIGH . The sensor’s temperature is too high. The
sensor’s ambient operating range is 10° to 46° C. When the ambient temperature returns
to this range, this message is automatically removed and operation is restored.
WARM UP or WARM (appears in the numerics area) . The sensor heater is warming up.
Wait 20 to 30 seconds for the sensor to heat. Values should appear in the numerics area
when the sensor is sufficiently warm.
