Cleaning and troubleshooting
42
Clean devices and accessories
Clean devices and accessories between each patient according to the procedure below.
Belts and cannula are single use and must be changed between each patient.
Procedure
To disinfect the different elements, the following products can be used:
Nox T3
Abdominal
cable
• 70-90% isopropanol
• Super Sani-Cloth Plus disinfection wipes
• Sodium hypochlorite diluted with water at 1:500 (bleach)
Clean the cables with a moist cloth using hospital grade cleaner.
Clean the Nox T3 device with a soft cloth dampened with hospital grade cleaner that is not corrosive to
plastic or metal. Do not pour or spray any liquids onto the device, and do not allow any liquids to enter
any openings on the device. Do not immerse the cables in liquid and avoid contact between the cleaning
solution and the connectors.
Oximeter
3150
SpO
sensor
Use a soft cloth with a 10% bleach / 90% water solution (household bleach < 10% sodium hypochlorite)
to clean the device. Do not use undiluted bleach or any other cleaning agent because it could cause
permanent damage.
Disconnect the probe from the oximeter before cleaning.
Use a soft cloth with a 10% bleach / 90% water solution (household bleach < 10% sodium hypochlorite)
to clean every part that is in contact with the patient.
2
Do not autoclave. Do not submerge or immerse sensor or connector plug.
Do not use caustic or abrasive cleaners. Do not use ammonium chloride-based cleaning fluids. Using
these products could shorten the lifespan of the devices.
The use of any other cleaning agent, especially ammonium chloride, is strongly discouraged as there is a high risk it will shorten
the lifespan of the device and its accessories.
43
Troubleshooting
For any issue not listed below, please contact your ResMed representative.
I don’t have oximetry data on my recording
Solution 1:
Solution 2: Check battery status
Solution 3: Conduct the pairing process as described on page 12
Solution 4: Check that the saturation sensor is working and that values are displayed when you put your finger into the probe
Solution 5:
My recording stopped prematurely
Solution 1:
Solution 2: Download the recording again
I can’t download the recording
Solution 1: Check that you have access to your database test by opening old recordings
Solution 2: Try using a different USB port on your PC (ideally at the back of the PC)
Solution 3:
My Nox T3 is not recognised / There is an error message at the end of the configuration
Solution 1: Reboot the computer and try again
Solution 2: Try using a different USB port on your PC (ideally at the back of the PC)
Solution 3:
My patient isn’t in the library
Solution: Right click on My Recordings and select Rescan Location

1. Connect the Nox T3 to a computer and click on the right button of the device until you see a reset menu.
2. Hold down the central button until the progress bar ends.
3. Once the device is restarted, it is completely reset.
47
Troubleshooting: Reset a Nonin 3150 oximeter
If the Nonin 3150 oximeter does not perform as expected, it is recommended that you follow the reset process described below:
1. Remove the two batteries and disconnect the probe from the oximeter.
2. Wait for 1 minute and reinsert the batteries.
