Does it need refills?
It needs no refills.
Where should I plug in the AIRPURIFIER CAR?
In the 12 V power socket in your car.
Can I plug in more than one AIRPURIFIER CAR?
Some cars include a second 12 V socket for the back seats
or in the trunk. The use of more than one AIRPURIFIER CAR,
in the trunk, for example, if you are carrying a pet there, will
strengthen the effect.
What if the indicator light is not working?
Check to see if the AIRPURIFIER CAR comes on if you plug
it into another 12 V outlet. If you confirm that it still does
not come on, get in contact with the RADARCAN® technical
department.
