The pressure value can then be changed by using the ON/OFF
and Ramp keys.
The ramp function enables you to make the rise in pressure progressive. Thus, the pressure level is
low at the start of the night to help you to fall asleep. You can also use this function if you have to
get up during the night and have difficulty going back to sleep. The pressure rise time up to the final
pressure is prescribed by your medical team and the setting carried out by your service provider is
between 0 (no progressive rise) and 30 minutes in 5-minute increments. The ramp may have been
preset to 0 according to your medical team’s prescription. In this case, the ramp function is disabled
and pressing the Ramp button on the front panel of the device has no effect. (Refer to reference 3 in
Figure 2, page 5).
1. To start the ramp, just press the Ramp button when the device is on. The pressure will fall to a
lower value, as previously described, then increase progressively up to the prescribed pressure
level, so as not to wake you. The device will run normally, delivering a treatment pressure
throughout the night unless you press the Ramp button again.
2. To end the ramp, press the Ramp button again and the function will be disabled. To reset the
ramp, press the ramp function again (the ramp indicator lights up when this is activated).
