The ResMed DC Adapter ("Adapter"),
provides an additional method of operating
an Astral
™
device where AC mains power is not
available.
The Adapter plugs directly into a standard
DC socket (eg, an automotive cigarette
lighter socket) to power the Astral device
and charge the internal battery.
The Adapter can be used with power
sources ranging from 12V to 24V DC.
WARNINGS
• Read instructions before use.
• The Adapter must only be used with
the Astral series of ventilators.
• When using the Adapter, do not touch
the connections at the back of the
Astral device.

• Do not connect the car battery to an
AC charger while the DC Adapter is
connected to the Astral device.
• Do not attempt to modify the Adapter,
there are no user-serviceable parts
inside.
• If using supplemental oxygen with
the Astral device, ensure oxygen
is turned off prior to connecting or
disconnecting the adapter. Only
use oxygen in a well-ventilated
environment.
CAUTIONS
• Always start the car before plugging in
the Astral.
• The Adapter is intended for use on
negative ground systems between 12V
and 24V (where the negative terminal
of the battery is grounded). Using it on
a positive ground system may damage
the Astral device and the vehicle's
electrical system. If you are unsure
whether you have a negative ground
system, consult the car, boat or other
vehicle manual.
• If the external DC power source drops
below 11V, the Astral will switch to
internal battery.
Notes:
• When powered from the Adapter, the
internal battery of the Astral device will
charge. The Adapter will not charge the
Astral External Battery.
• The vehicle's electrical system must be
in good condition. Have it checked by an
auto electrician if in doubt.
• For further assistance contact
ResMed or your authorised ResMed
representative.
