WARNING Use only accessories approved by Welch Allyn. Visit
www.welchallyn.com . The use of any other accessories can result in inaccurate
patient data, can damage the equipment, and can void your product warranty.
WARNING Always refer to the manufacturer's Directions for Use for instructions
about operation, cleaning, and replacement.
WARNING Do not attempt to verify operation of the CO
2
sensor by blowing
through it directly. Always blow through an attached airway adapter. Otherwise, a
small amount of CO
2
from your breath may enter the CO
2
sensor housing and
cause a small shift in the measured CO
2
values. It may take 3-24 hours for the
sensor to return to proper calibration.
WARNING Do not clean and/or reuse a single-patient-use airway adapter. When
a single-patient-use airway adapter becomes occluded, replace it.
WARNING Prior to using an airway adapter, always look through the window
lumen and inspect the adapter for inadvertently lodged obstructions and for
window integrity.
WARNING If the sensor does not easily slide onto the adapter, do not attempt to
force these components together. They fit together in only one way. Take care not
to damage the glass windows.
WARNING After attaching the sensor to the adapter, check the adapter again for
proper placement of the sensor and for window integrity.
WARNING When attaching the airway adapter, position the adapter so the
sensor is on top to avoid fluid collection in the sensor airway slot. Any
concentration of fluids here can cause inaccurate CO
2
readings.
WARNING Always check to make sure there are no leaks in the breathing
circuit. Check all of the connections.
