Repair Service (RMA)

Step 1: To return products, you will need an RMA number. You can request one by phone +49 8171 3492-0, fax +49 8171 3492-16, or by email ( It would help us greatly if you would indicate the delivery order number or invoice number, serial number, article number, customer number and a detailed description of the issue.

Step 2: Pack the device in its original packaging so it is safe for transport and ESD-compliant. Please mark the RMA number clearly on the packaging. Please include inside the packaging a detailed description of the problem for each device. Send the goods to us.

We generally require two to four weeks for the in-house testing and repair. Any necessary procurement of spare parts or repair by the original manufacturer can prolong the processing time.
