RMA Process

Step 1. To avoid unnecessary RMAs, HMS requires that you work with our Technical Services team to troubleshoot the device before an RMA is issued. We will work to quickly resolve the issue or issue an RMA for your device to be replaced or repaired.

Step 2. If the device requires an RMA, HMS Technical Services will issue a ticket number. This number identifies the steps we took to troubleshoot the issue.

Step 3. Contact your local distributor and provide the ticket number. Your local distributor will reach out to us and handle the process going forward.

NOTE: If you are an HMS distributor, you can proceed to the HMS RMA portal. You will use this RMA portal to enter a request for an approved RMA. After the RMA is processed and accepted you will receive shipping information. If you have questions or need support accessing the portal please contact returns@hms.se or call customer service at +1-312-829-0601.


I think my device is damaged can I ship it back for you to troubleshoot?

Before we accept a return we require the device be troubleshot with an HMS support engineer. We will provide trouble shooting support over the phone, via TeamViewer, and right here on hms.how.
