You can decide to conclude an RMA (return merchandise authorisation) with Kappa Data, which is the easiest way to return defective products for replacement or repair. This does depend on you having correct, active licenses that were purchased from Kappa Data.
Do you have an RMA-related question about an ExperTechno project/device? Then click on this link.
If you have not concluded an RMA, or you do not have the correct licenses, you can only contact the manufacturer directly.
Please note: The package may only be returned once you have received confirmation (via e-mail) from Kappa Data with an RMA number.
