After 14 days from the delivery date, only the warranty (complaint) procedure applies – product returns are no longer possible. Under the warranty, we provide full technical support, product testing, and – if a defect is confirmed – replacement or repair (if the issue is minor and does not affect the proper operation of the unit).

In the case of a complaint, the issue must be reported immediately, including the error code and a detailed description of the problem.

If the issue cannot be resolved remotely, the product must be sent back to our company address along with a description of the problem and any error codes.
