provided by external batteries may change. To prevent switch-offs from
the external battery due to normal fluctuations in DC voltages, the
iVent
TM
201 is programmed to average the external DC voltage reading
over time. Therefore, if the user disconnects the external battery, the
ventilator interprets this as a dying battery and switches off the external
DC source for power. To re-enable input from the external battery
source, the user must leave the external battery disconnected for 40
seconds before reconnecting the external battery
INTERNAL BATTERY
The ventilator switches to an internal battery when it detects a loss of external
power. When fully charged, the internal battery can supply approximately 1 to 2
hours of power, under typical conditions and settings.
NOTE The extended internal battery can supply approximately 3 to 4 hours of
power under typical conditions and settings
CAUTION The iVent
TM
201 should only be used with a properly functioning battery.
The battery is automatically charged when attached to an external power source,
whether the ventilator is operating, in Standby mode, or switched off.
Batteries should undergo a full recharge procedure:
Prior to initial use
After prolonged storage
Every 3 months during normal use
If after 8 hours charging, the battery indicator fails to indicate a full charge
