FOR AC 110V USE
This unit is manufactured at the factory fox use with AC 220V. If you need to change this unit fem AC 220V use to AC
110V use, efeleying changes should be made.
1. Remount the seinen terminals of the power transformer (4-320T-15800) mounting on the 220V position of the PC
Board (4-285T-87700) to 110V position as shown in wiring diagram.
2. Change the fuse F901 from 4-234T-10585 (250V 11.25) to 4-234T-10589 (250V T2.5A).
