Care and Use of the Stellar™ 150

Internal Battery and Internal Battery Alarm Messages

• The internal battery duration on your Stellar™150 depends on:
1. the state of charge,
2. the environmental conditions,
3. the condition and age of battery,
4. the device settings and the patient circuit configuration (different settings and types
of circuits have different amounts of power drawn from the internal battery when in
use).
• Battery replacements, when needed, must be performed by the VEP. Internal batteries
are not serviceable or able to be changed by clients. If you have any concerns regarding
the function of the internal battery on your device, contact the VEP for troubleshooting
and replacement of the battery if needed.
• In case of a mains power disruption, the device will operate using the internal battery if
there is no external battery connected to the device.
• The internal battery will operate for approximately two hours under normal conditions.
The power status of the battery is displayed on top of the 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 displayed. Press the Alarm mute
button to clear the alarm.
• To recharge the internal battery, connect the device to mains 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.
• 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%.
