external and internal batteries combined are capable of powering the ventilator and compressor for a period equal to or
greater than 2 hours, and the ventilator on wall air for a period equal to or greater than 4 hours.
Both battery types are re-chargeable and require some maintenance when installed.
The internal battery should be discharged and recharged approximately once every three months.
The external battery should be discharged and recharged approximately once every twelve months.
The Battery Status Indicators on the front panel enable you to monitor the battery charge remaining (see "Chapter 7:
Alarms and Indicators").
CAUTION
Should your internal battery require replacement, contact your CareFusion representative. Do NOT attempt to replace
the battery yourself. The battery should only be replaced by a qualified technician.

Precedence of power use

The sequence in which the power sources are used by the ventilator is:
1. AC
2. External Battery (if installed)
3. Internal Battery
CAUTION
Do not store the ventilator in hot areas for prolonged periods of time. Temperatures above 80°F (27 °C) can shorten
battery life. Failing to charge the ventilator while in storage may also shorten battery life.
CAUTION
When the integrity of the external power ground conductor arrangement is in doubt, operate the ventilator from its
internal battery or the optional external battery.
Note: Refer to the Service Manual for battery maintenance and testing procedures.
