Astrodyne products carry a 2-year warranty (from date of shipment) against defects in material or workmanship. Astrodyne will repair or replace, at its sole discretion, any product returned and found to be defective. To assure proper handling and credit, all returned products must have a Returned Material Authorization (RMA) number. Please contact the factory at (908) 850-5088 to obtain an RMA number prior to returning any product. Product returns without an RMA number will not be accepted. Astrodyne is not responsible for products returned without an approved RMA number. The customer is responsible for return shipping charges, Astrodyne will assume shipping charges for repaired/replaced products back to the customer. Failure Analysis Reports are available upon request at the time of RMA issuance, at an additional cost of $150.00 per RMA. To facilitate handling, please have your work order or invoice number at hand when contacting the factory for an RMA number. Please mark the RMA number on the outside of the shipping box/label for easy recognition.
