General warnings and cautions
WARNING
•Make sure that you arrange the air tubing so that it will not twist around the head or neck.
•Make sure the power cord and plug are in good condition and the equipment is not
damaged.
•Keep the power cord away from hot surfaces.
•If you notice any unexplained changes in the performance of the device, if it is making
unusual sounds, if the device or the power supply are dropped or mishandled, or if the
enclosure is broken, discontinue use and contact your care provider or your ResMed
Service Center.
•Do not open or modify the device. There are no user serviceable parts inside. Repairs and
servicing should only be performed by an authorized ResMed service agent.
•Beware of electrocution. Do not immerse the device, power supply or power cord in water.
If liquids are spilled into or onto the device, unplug the device and let the parts dry. Always
unplug the device before cleaning and make sure that all parts are dry before plugging it
back in.
•Supplemental oxygen must not be used while smoking or in the presence of an open
flame.
•Always make sure that the device is turned on and airflow generated before the oxygen
supply is turned on. Always turn the oxygen supply off before the device is turned off, so
that unused oxygen does not accumulate within the device enclosure and create a risk of
fire.
•Do not perform any maintenance tasks while the device is in operation.
•The device should not be used adjacent to or stacked with other equipment. If adjacent or
stacked use is necessary, the device should be observed to verify normal operation in the
configuration in which it will be used.
•The use of accessories other than those specified for the device is not recommended. They
may result in increased emissions or decreased immunity of the device.
•Regularly check the antibacterial filter for signs of moisture or other contaminants,
particularly during nebulization or humidification. Failure to do so could result in increased
breathing system resistance.
•The AirCurve 10 ST-A device has not been tested or certified for use in the vicinity of X-ray,
CT or MRI equipment. Do not bring the AirCurve 10 ST-A device within 13 ft (4 m) of X-ray
or CT equipment. Never bring the AirCurve 10 ST-A device into an MR environment.
•Therapy settings should not be changed remotely for patients in a hospital setting.

18
CAUTION
•Use only ResMed parts and accessories with the device. Non-ResMed parts may reduce the
effectiveness of the treatment and/or damage the device.
•Use only vented masks recommended by ResMed or by the prescribing doctor with this
device. Fitting the mask without the device blowing air can result in rebreathing of exhaled
air. Make sure that the mask vent holes are kept clear and unblocked to maintain the flow
of the fresh air into the mask.
•Be careful not to place the device where it can be bumped or where someone is likely to
trip over the power cord.
•Blocking the air tubing and/or air inlet of the device while in operation could lead to
overheating of the device.
•Keep the area around the device dry, clean and clear of anything (eg, clothes or bedding)
that could block the air inlet or cover the power supply unit.
•Do not place the device on its side as water might get into the device.
•Incorrect system setup may result in incorrect mask pressure reading. Ensure the system is
correctly set up.
•Do not use bleach, chlorine, alcohol, or aromatic-based solutions, moisturizing or
antibacterial soaps or scented oils to clean the device, the humidifier or air tubing. These
solutions may cause damage or affect the humidifier performance and reduce the life of
the products.
•If you use the humidifier, always place the device on a level surface lower than your head
to prevent the mask and air tubing from filling with water.
•Leave the water tub to cool for ten minutes before handling to allow the water to cool and
to make sure that the water tub is not too hot to touch.
•Make sure that the water tub is empty before transporting the device.
Note: The device is not intended to be operated by persons (including children) with reduced
physical, sensory or mental capabilities without adequate supervision by a person responsible for
the patient's safety.
