WARNING
• Make sure the power cord and plug are in good condition
and the equipment is not damaged.
• Only ResMed air tubing should be used with the device.
A different type of air tubing may alter the pressure you
actually receive and reduce the effectiveness of your
treatment.
• Blocking the tubing and/or air inlet of the device while in
operation could lead to overheating of the device.
•
Use care when handling the air tubing. Be particularly
careful when attaching the Luer connector to the device. If
you kink or excessively twist the sensor tube, it may affect
the protection offered by the mask pressure alarm system.
CAUTION
• Be careful to place the device where it cannot be bumped,
and where no one will trip over the power cord.
• If you put the device on the floor, make sure the area is free
from dust and clear of bedding, clothes or other objects
that could block the air inlet.
