WARNING
Do not immerse the External Battery in water, and do
not pour liquids or solvents onto any part of the External
Battery.
The following cleaning solutions are compatible for use on a
weekly basis (except as noted) when cleaning the external
surfaces of the Astral device:
• Isopropanol
• Actichlor Plus
• Bleach (1:10) (may also be known as 'dilute hypochlorite').
• Cavicide*
• Mikrozid*
*Suitable for cleaning on a monthly basis only.
Storage
Ensure that the External Battery is clean and dry before storing
for any length of time. Store the External Battery in a dry place
out of direct sunlight.
CAUTION
• The External Battery must be charged to at least 65-90%
(indicated by three green LEDs) and switched off before
storing.
• Storing the External Battery at high temperatures
increases the rate of self-discharge.
WARNING
• When not in use, all Lithium-ion batteries self-discharge
over time. Recharge the External Battery to at least 65-90%
after six months of storage.
• If not periodically recharged (ie, every six months), the
External Battery will eventually self-discharge to the
point that it can no longer be recharged. If this occurs the
External Battery is no longer usable and is unrecoverable.
Servicing
The External Battery should be serviced by an authorised
ResMed Service Centre every two years. The External Battery
is intended to provide safe and reliable operation provided that it
is operated and maintained in accordance with the instructions
provided by ResMed. As with all electrical devices, if any
irregularity becomes apparent, you should exercise caution and
have the device inspected by an authorised ResMed Service
Centre.
