have the optional DeVilbiss SmartLink Module attached to your device, which provides additional messages. Refer to the
documentation that was provided with the SmartLink Module.
Clean Filter – The filter should be checked every 10 days for signs of dirt or wear so that it can be cleaned as needed.
This message helps to remind you to check it regularly.
Notifications
Notifications identify conditions in your SleepCube that may require action by you or your equipment provider in order to
maintain a high level of therapy. If you see a message on the display that is not listed below, you may have the optional
DeVilbiss SmartLink Module attached to your device, which provides additional messages. Refer to the documentation that
was provided with the SmartLink Module.
Delay Running xx Minutes Left – While a comfort delay session is active, this message is flashed on the display every 5
seconds to let you know how much time is left in the delay.
Mask Leak – This message means the SleepCube has detected a large amount of airflow during therapy for at least 10%
of the time during your previous use session. This notification is displayed when the device is turned on. If this message is
displayed, put on the mask and adjust the headgear to ensure the mask is properly fitted to your face. Follow the mask
manufacturer's directions for adjusting the mask and headgear for proper fitting.
Mask Off – This message appears due to a poor mask fit or a removed mask. Check for leak around the mask seal and
make adjustments as necessary according to the mask manufacturer's instructions. This message will be displayed until
the high airflow problem is corrected. If the high airflow condition persists for about 20 seconds, the device will
automatically turn off if Auto-OFF is enabled.
Device Fault – If a device fault message is displayed, refer to Troubleshooting for instructions.
SLEEPCUBE TRAVEL INFORMATION
International Power Changes
Your DeVilbiss SleepCube is equipped with a universal power supply. This means that it is automatically capable of
accepting line voltages of 100 to 240V~ 50/60Hz. You do not need to make any adjustments to the device if you are
traveling to another country where the line voltage is different than your domestic line voltage. Simply contact your
equipment provider for the correct style power cord for the region in which you will be traveling (refer to Accessories/
Replacement Items for the correct part number).
Altitude
Your SleepCube automatically compensates for changes in altitude between sea level and 9000 ft (2750 m). You do not
need to make adjustments to the device for changes in altitude.
SLEEPCUBE DC OPERATION
Battery Power
Your SleepCube can be operated from a 12V DC power source in a motor home, boat or other recreational vehicle using
the 12V DC cable. Alternatively you can power your SleepCube using a 12V DC stand alone battery with a DC battery
clamp on adapter and 12V DC cable. All cables are available from your equipment provider (refer to Accessories/
Replacement Items for the correct part numbers). The stand alone battery connection uses clamps that attach to the
terminal connections of the battery.
NOTE–The heater for the SleepCube's humidification system will not operate directly from a 12V DC power source. If you
need humidification, non-heated humidification is still available. Alternately, instead of connecting12V DC power directly to
the SleepCube, you can pass the DC power through an inverter that will deliver AC power to the system. This will allow the
heater to function. The power rating of the inverter must be at least 200 watts @ 110V~ / 400 watts @ 220V~.
NOTE–The SleepCube will automatically switch power sources between AC and 12V DC if both sources are available. If
your unit is connected to both AC and 12V DC power sources, it will operate on AC power as long as AC power is present,
and automatically switch to 12V DC power if AC power is lost. When AC power is restored, it will return to the AC source.
You do not need to reset or adjust any settings when the power source switches, but remember that your heater will not
operate on 12V DC.
