The ventilator can operate from a mobile power source by connect-
ing the ventilator to a 12 V battery and disconnecting the AC power.
A
POWER SWITCHOVER
alarm signals the change from an AC power
source to an external battery. A deep-cycle battery, 74 amp-hour in
good condition, can operate the ventilator without recharging for
approximately 24 hours. A gel-cell type battery (34 amp-hour) can
operate for approximately 10 hours between recharges. The ventila-
tor is capable of recharging an external battery, but it is less effi-
cient than using a standard battery charger. Approximately three
hours recharge time is required for each hour of use
.

The ventilator switches to its internal battery should the AC power
source fail or the unit become disconnected from the power source.
The internal battery also takes over automatically when power from
an external battery becomes inadequate. A
POWER SWITCHOVER
alarm
signals the change to internal power. The ventilator can operate
from 30 to 60 minutes on the internal battery, depending on the
charge level and on the control settings. Therefore, the internal bat-
tery should be used only for emergency power backup.
The amber
INTERNAL BATTERY
light flashes continuously, and a single-
tone audio alarm sounds every five minutes when the internal bat-
tery is in use. The ventilator charges the internal battery in three
hours when the ventilator is connected to AC power and the
MODE
switch is in any position. A discharged internal battery must be
recharged for at least three hours prior to turning off the ventilator
to prevent shortening internal battery life.
