Change EPROM on 2706-P72, 2706-P74 Display
The firmware kit comes with two EPROMs. One is a chip carrier type and the other
is a round-pin DIP socket with the chip installed. Use the one that fits your
controller board.
Follow these steps to change the EPROM on the 2706-P72 and 2706-P74 displays.
1. Open the front of the sign case by turning the latches to the left.
Carefully let the front of the case drop forward.
ATTENTION
Hazardous voltage. Contact with high voltage may cause death or serious injury. Always
disconnect power to sign prior to servicing.
