Unit Exchange/Replacement Procedure
Daktronics unique exchange program offers our clients the quickest, most economical way of
receiving product repairs. If a component fails, Daktronics will send the customer a
replacement. The customer, in turn, sends the failed component to Daktronics. This not only
saves money but decreases the time the display is inoperable. Daktronics offers repair and
return on a timely basis; in urgent situations, every attempt is made to ship by the fastest
transit method available.
1. Packaging for Return: Package and pad the item well to prevent damage during
shipment. Electronic components, such as printed circuit boards, should either be
installed in an enclosure or placed in an anti-static bag before boxing.
Please enclose your name and address along with a list of all the symptoms. Please be
as specific as possible.
2. Driver Packaging Instructions: Drivers should be placed in a static-free enclosure
for return shipping. An anti-static convoluted foam packing is available from
Daktronics (part number PK-1135). The shipping box (Daktronics part number PK-
1006) should be used along with the foam.
3. Where to Send: Contact your local representative prior to shipment to acquire a
Return Material Authorization Number (RMA#). This will speed up the repair of
your unit.
