Confirming if Repair is Required
If you are experiencing difficulties with your equipment, we strongly urge you to first contact our service department. A service technician can help you verify the problem and can guide you through troubleshooting. For more information on our service support structure, please see our service support page.
Returning Equipment
Upon confirmation that repair service is required, please submit a Repair Authorization (RA) form. The RA form serves as a request to receive a Return Material Authorization (RMA) number and allows OTC DAIHEN to receive proper payment information before the repair occurs.
Note: An RMA# must be obtained prior to shipping any equipment in for repair.
If you have any further details, please contact the service coordinator.
