it is also plugged into an inverter. e blue LED will flash when the heater
plate does not heat up. In this mode, the humidifier acts as a pass-over, or
non-heated, humidifier.
CAUTION: When DC power is obtained from a vehicle battery, the device should not
be used while the vehicle’s engine is running. Damage to the vehicle or the
device and humidifier may occur.
CAUTION: Only use a Respironics DC Power Cord and Battery Adapter Cable. Use of
any other system may cause damage to the device or vehicle.
Refer to the instructions supplied with the DC power cord and adapter cable for information on how
to operate the therapy device and humidifier using DC power.
