Troubleshooting
Your device is equipped with a self-diagnostic tool call “Performance Check”. This tool can evaluate your device for certain errors. It
also allows you to share key device settings with your Provider. Use Performance Check when directed by your provider.
The table below lists some of the problems you may experience with your device and possible solutions to those problems.
Problem
Why It Happened
What To Do
Nothing happens
when you apply
power to the device.
The backlights on
the buttons do not
light.
There’s 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 airflow does not
turn on.
There may be a
problem with the
blower.
Make sure the device is powered correctly. Make sure the Home screen appears on
the user interface. Press the Therapy button on top of the device to start airflow.
If the airflow does not turn on, there may be a problem with your device. Contact
your home care provider for assistance.
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.
The Ramp feature
does not work when
you press the Ramp
button.
Your home care
provider did not
prescribe Ramp
for you, or your
therapy 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
current pressure setting on the Therapy screen. If the therapy pressure is set to the
minimum setting (4.0 cm H
2
O), or the Ramp starting pressure is the same as the
therapy pressure, the Ramp feature will not work. Make sure that the ramp time
setting is >0.
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.
