UI Step

We will verify your claim and check the AirID device

After receiving your non-functional device, we will check your warranty claim and we will analyse the device. In case of a valid warranty claim, we always will try to repair your device first and return the repaired device back to you. In case that a repair is technically or economically not possible, we will send you a new AirID device as a replacement. At our sole discretion, we may replace your device with a newer version. 

If your warranty claim will not be valid, or the RMA form is missing or not completed, we will have either to return or trash your device. In this case, we will inform you by mail and trash the non-functional device or we will return it on request.
