If you do not own the original invoice, please upload a picture of the serial number which is visible on the label of the device.
Please understand that in the event of a missing receipt or proof of purchase, we will take the date we first sold the devices as a reference to calculate the remaining warranty time of the device.
Please note, that this might be earlier than your actual purchase date, if you ordered through another distributor.
The serial number of my device is no longer readable. How can I register my device anyway?
