Internal battery
CAUTION
The internal battery must be replaced every two years from the manufacturing date
of the Stellar. Replacement of the internal battery should only be performed by an
authorised service agent.
Note: The battery duration depends on the state of c
harge, the environmental conditions,
the condition and age of battery, the device settings and the patient circuit configuration.
In case of a mains power disruption, the device will operate using the inte
rnal battery if
there is no external battery connected to the device. The internal battery will operate for
approximately two hours under normal conditions (see “Technical specifications” on
page 26). The power status of the battery is displayed on top of th
e LCD screen. Check the
battery status regularly while operating
the device with the internal battery and connect the
device in time to mains power or alternatively to the external battery.
Additionally the Internal battery use alarm
will be d
isplayed. Press the Alarm mute button
to clear the alarm.
To recharge the internal battery, connect the device to main
s power. It can take
up to three
hours to fully recharge the internal battery, however this can vary depending on
environmental conditions and if the device is in use.
Storing
The internal battery has to be discharged and recharged every six months.
1 Remove the power cord while the Stellar is providing therapy and let the device operate
with the internal battery to a charge level of 50%.
2 Reconnect the power cord to the mains power while the device is operating. The internal
battery will be recharged.
Note: If the
device is stored for a longer period the internal battery should be at the charge
level of approximately 50% to increase the durability.
