WARNINGS
• When the device is in operation mode, check that it delivers an airflow. If no airflow is felt,
turn off the device and contact the service provider.
• At lower CPAP pressures, the flow through the exhalation port may be inadequate to clear
all exhaled gas from the hose. Some rebreathing may occur.
Stopping treatment
When the GoodKnight 420G is operating, follow the instructions below to discontinue the treatment:
1. If you are using oxygen, stop the flow now.
2. Remove the interface (nasal mask).
3. If you are using a heated humidifier, turn it off according to the instructions for use. Disconnect
the humidifier from the unit.
CAUTION
Do not leave the humidifier connected to the unit or to the tubing when the humidifier is
not in use, as humidity could enter the device and degrade device performance.
4. Turn the device off by pressing the ON/OFF button. The device will return to standby mode and
display the following standby screen showing the time:
9:38 Ÿ
CAUTION
Check that no humidity appears in the tubing. If so, let the tubing dry before you use it again.
