How to send devices for R&M by delivery?
a. Apply RMA list and non-commercial invoice from service center.
b. Please declare delivery as normal USB barcode reader with the piece of $20 per unit and do not send back the accessories especially batteries if they are working fine. Please send back by TNT if it is possible since this would be easier for custom clearance. Fill and send RMA request sheet and non-commercial invoice. And send the faulty devices no more than 3 pieces in one packet.
