Daktronics expects immediate return of an exchange part if it does not solve the problem. The 
company also reserves the right to refuse equipment that has been damaged due to acts of nature or 
causes other than normal wear and tear. 
 
If you do not ship the defective equipment Daktronics within 30 working days from the invoice date, 
Daktronics assumes you are purchasing the replacement part outright (with no exchange), and you will 
be invoiced for it. This second invoice represents the difference between the exchange price and the 
full purchase price of the equipment. The balance is due when you receive the second invoice. 
If you return the exchange equipment after 30 working days from the invoice date, you will be 
credited for the amount on the second invoice, minus a restocking fee. 

To avoid a restocking charge, 

you must return the defective equipment within 30 days from the invoice date. 

 

Daktronics also offers a Repair and Return Program for items not subject to exchange. 

 
Return Materials Authorization:

 To return parts for service, contact your local representative prior 

to shipment to acquire a Return Material Authorization (RMA) number. If you do not have a local 
representative, call the Daktronics Help Desk for the RMA. This expedites repair of your component 
when it arrives at Daktronics. 

 

Packaging for Return: 

Package and pad the item well so that it will not be damaged in shipment. 

Electronic components such as printed circuit boards should be installed in an enclosure or placed in 
an antistatic bag before boxing. Please enclose your name, address, phone number and a clear 
description of symptoms.
