Fuses on the AAS (Analog Address System)

F1 is located in the upper left corner of the AAS processor near the 120 VAC input. If blown the AAS display will be out, there will be no LEDs lit on the board, and there will be no function from the processor. F1 = .5A 5x20mm and is ETC part number F112

F2 is located above J9. If blown, the AAS display and buttons will work fine, but the CR7 LED will be dark and no stations will function. Typically this is blown because the 12 VDC line was shorted. F2 = .5A micro-fuse and is ETC part number F124. It is also Littelfuse Part number 273.500 and DigiKey part number F863-ND.
