The device will automatically switch off the ventilation 5 minutes after the “Internal
battery empty” alarm occurs. A notice window will appear “Ventilation currently not
possible. Internal battery empty”. The device will switch off once another minute has
passed. This prevents the battery from being fully drained and ensures the device shuts
down properly.
Please note:
This 5-minute period cannot be maintained if the battery was deeply dis-
charged and was not charged up to 10%. In such a case, ventilation will end imme-
diately.
Charge battery
To charge the battery, operate the device using the mains power. Recharging a fully
discharged battery takes approximately 2.5 hours in mains operation. The device is
fully functional during recharging.
Please note:
The battery begins charging when the power level falls below 95%.
Power failure
Please note:
During a power failure, the battery capacity display must be monitored
and an alternative power source kept ready.
If the power supply is interrupted by a power failure and the device is on, the device
is supplied with power via the internal battery.
Power failure and thus the switch to the internal battery is indicated by an alarm sound,
as well as by the message “Power Failure”.
When the power supply returns, the device is supplied with power from the mains
supply and the internal battery is charged.
Operation without internal battery
Please note:
If the device is operated without a battery, it shuts off immediately in
case of an interruption to the power supply. Connect the device to an alternate power
supply right away.
If the power supply is interrupted during ongoing ventilation, an acoustic signal is
output for approx. 2 minutes. The acoustic signal can be deactivated by pressing the
on/off button.
