Problem
Why it happened
What to do
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 at least 5
minutes.
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 and lower the setting, if possible.
Make sure there is water in the humidifier water
tank. Refer to the humidifier instructions to make
sure the humidifier is working properly.
If the problem continues, contact your home care
service 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 the Tubing type setting has been
changed, contact your home care service provider.
If you are using the heated tubing, this setting will
be 15H and cannot be changed.
Tube Temperature is
turned on but heated
tubing is not warm.
Incorrect power supply
is being used.
Make sure the 80W power supply is being used or a
compatible battery or DC cable is being used.
