The battery no longer has enough charge.
The battery must be changed if ventilation hood functions can no longer be selected using the remote control. If the indicator light on the remote control no longer lights up or lights up only weakly when a control is pressed, the battery is exhausted. Ventilation hood functions can still be selected using the controls on the ventilation hood.
Remove the lid from the back of the remote control.
Remove the old battery and replace with a new one.
Make sure the polarity is correct.
Reattach the lid.
Dispose of used batteries as required by your local municipality.
