Why It Happened
What to Do
The device’s display is erratic.
The device has been dropped
or mishandled, or the device
is in an area with high
Electromagnetic Interference
(EMI) emissions.
Unplug the device. Reapply power to the device. If the
problem continues, relocate the device to an area with
lower EMI emissions (away from electronic equipment
such as cellular phones, cordless phones, computers, TVs,
electronic games, hair dryers, etc.). If the problem still
occurs, contact your home care provider for assistance.
Nothing happens when you apply
power to the device. The backlights
on the buttons do not light.
There is no power at the
outlet or the device is
unplugged.
If you are using AC power, check the outlet and verify
that the device is properly plugged in. Make sure there is
power available at the outlet. Make sure the AC power
cord is connected correctly to the power supply and the
power supply cord is securely connected to the device’s
power inlet. If the problem continues to occur, contact
your home care provider. Return both the device and
power supply to your provider, so they can determine if
the problem is with the device or power supply.
If you are using DC power, make sure your DC power
cord and battery adaptor cable connections are secure.
Check your battery. It may need recharged or replaced. If
the problem persists, check the DC cord’s fuse following
the instructions supplied with your DC cord. The fuse
may need to be replaced. If the problem still occurs,
contact your home care provider.
The Ramp feature does not work
when you press the Ramp button.
Your home care provider
did not prescribe Ramp for
you, or your prescription
pressure is already set to the
minimum setting.
If Ramp has not been prescribed for you, discuss this
feature with your home care provider to see if they will
change your prescription.
If your provider has enabled Ramp, but the feature still
does not work, check the pressure setting on the Monitor
Pressure screen. If it is set to the minimum setting (4.0
cm H
2
O), or the starting pressure is the same as the
prescribed pressure, the Ramp feature will not work.
The airflow is much warmer than
usual.
The air filters may be dirty.
The device may be operating
in direct sunlight or near a
heater.
Clean or replace the air filters.
The temperature of the air may vary somewhat based
on your room temperature. Make sure that the device is
properly ventilated. Keep the device away from bedding
or curtains that could block the flow of air around the
device. Make sure the device is away from direct sunlight
and heating equipment.
If using the humidifier with the device, check the
humidifier settings. Refer to the humidifier instructions
to make sure the humidifier is working properly. If the
problem continues, contact your home care provider.
The airflow pressure feels too high
or too low.
The Tubing type setting may
be incorrect.
Make sure the Tubing type setting (22 or 15) matches the
tubing that you are using (Philips Respironics 22 or 15
mm tubing).
If you are using the Heated Tubing, this setting will be
15H and you cannot change it.
Tube Temperature is turned on in
“Setup” screen but Heated Tubing is
not warm.
Tube Temperature is turned on in
“Setup” screen but Humidifier LED
does not stay orange (changes to
blue).
Incorrect power supply is
being used (60W is used
instead of 80W).
Heated Tubing is attached
incorrectly or damaged.
Make sure the 80W power supply is being used. This can
be confirmed by looking at the power supply for the 60W
or 80W symbols. This can also be checked by looking at
the “Humidifier” settings under the “Info” screen.
Inspect Heated Tubing for damage and reconnect. If the
problem continues, contact your home care provider.
The mask feels uncomfortable to
wear, there is significant air leakage
around the mask, or you experience
other mask-related issues.
This could be due to
improper headgear
adjustment or improper
mask fitting.
Make sure you are properly fitted with the correct size
mask. If the problem continues, contact your home care
provider to be fitted with a different mask.
