Power
The Astral runs on mains power and can be used with different power sources. These includes internal battery
power, external battery power and car charger power source.
Removing the power lead
The power cord is equipped with a push-pull locking
connector. To remove, grasp the power cord housing
and gently pull the connector back- this will release the
power cord.
NEVER twist its outer housing or pull on the cord and
NEVER force the cord from the Astral as it will break the
collar and it cannot be repaired.

Internal Battery Power
The ventilator has an internal battery. Whilst the ventilator is connected to mains power the internal battery will
charge. When the mains power is disconnected the ventilator will automatically switch to using the internal battery
(assuming no external batttery is connected). There is no interuption to ventilation when this happens. The
ventilator will notify you of this change by sounding an alarm. The internal battery life is approximately 8 hours.
There will be slight variations in the battery life dependent on the individual child’s ventilator parameters and the
child’s respiratory pattern. Please observe the internal battery indicator carefully.
Warning:
•Please ensure to regularly check the internal battery.
•The internal battery should be replaced every two years, or when there is a noticeable reduction in usage
time when fully charged.
•Following a Field Safety Notice 1706001, MHRA has released a for the Astral ventilator (July 2017)
concerning the Astral power supply. Their current recommendations are that the internal battery is NOT
intended to serve as a primary power source. It should only be used when other sources are not available or
briefly when necessary; for example, when changing power sources. See image below.
Please Note: When the ventilator is running on internal battery power in standby mode no alarms will sound, take
care to observe the battery life indicator.

External Battery Power
The external battery will power the device for approximately 8 hours. A maximum of two external batteries can be
connected to the Astral device.
Please Note:
•There will be slight variations in the battery life dependent on the individual child’s ventilator parameters
and the child’s respiratory pattern. Please observe the internal battery indicator carefully.
•The external battery cannot be charged from your main power. This can be used and recharged while
connected to the Astral device.
Previous External Battery
This may still be seen in the community giving 8 hours of power during typical use.
Please Note: When using this battery, the internal battery will not be charged. Do not use this battery with the new
external battery seen above. This is charge using an adapter connected to main power.
