3.1.1  Cleaning the Disposable Mouthpiece/Rotary Flow 

Sensor

To clean the rotary sensor of the AM3, release the sensor by moving the releaser 
sidewards. It is recommended to clean the outer parts of the sensor every 4 weeks 
with a damp (not wet) cloth or tissue and letting the sensor air-dry at room  
temperature. Place the sensor back in the AM. 
The disposable mouthpiece can be cleaned under running water.
Any minor discoloration in the sensor does not affect the performance of the AM.

DO NOT use alcohol or any type of household cleaner!

Wipe off the case with a moist cloth. Then dry the case with a cotton towel.

3.1.3   Checking the Sensor

If the patient’s AM does not measure accurately, clean the sensor as described 
above. If there are still doubts that the device is not working correctly, exchange 
the sensor or contact the responsible Monitor or ERT Customer Care Helpdesk.
