WARNING:
Do not lift the External Battery. If the battery needs to be removed from the

When AC power becomes unavailable, the ventilator consumes power from the
battery systems as follows:
•
With external battery installed and turned ON and backup battery
installed: External battery power is consumed first until depleted.
Backup battery power is then used until depleted. An audible alarm
sounds when the backup battery is in use. The ventilator will not
operate when both batteries are depleted.
•
With backup battery installed only: Backup battery power is used until
depleted. An audible alarm sounds when the backup battery is in use.
The ventilator will not operate when the battery is depleted.
AC power can be restored to the ventilator at any time during battery use.
When AC power is restored the ventilator consumes AC power only, and both
batteries begin recharging. (See the Battery Charging section).
The external battery must be turned ON in order for the external battery to be
used. Make sure the ON/OFF switch located on the external battery (Figure 16)
is in the ON (I) position. When AC power becomes unavailable, the ventilator
automatically switches to external battery operation without interruption in
ventilation. When the external battery is depleted, the ventilator automatically
switches to backup battery power.
