Step 1: Unplug the ALPHA sign from its outlet or power source. Make sure to unplug the
unit from the outlet, not the back of the sign.
Step 2: Remove the Access Cover located on the back of the unit, by sliding it towards the
top of the sign:

Step 3: After removing the Access Cover, find the Two-Prong Receptacle located in the
compartment:
NOTE: On some models the Two-Prong Receptacle has been removed. If this is
the case on your sign, then go to Step 6. You will NOT use the jumper.
