EPROM REPLACEMENT
Software changes / upgrades are accomplished by
changing the EPROM on the Control Board.
Remove power to the AC Distribution Box and
proceed as follows:
Remove the cover from the Control Board (if one is
present).
Remove the Battery clip to allow the Board’s
memory to drain. (Leave the clip off for a minimum
of 10 minutes.)
Replace the EPROM. (The EPROM’s legs bend
easily. Remove and replace very carefully.)
Replace the Battery clip and cover (if used).
Apply power to the AC distribution box.
Go in the “Setup Mode” and push “F” for Master
Reset.
Go in the “Test Mode” and push “0” to clear errors.
