The Roland FC-200 MIDI Foot Controller can be powered by batteries or power supply (Boss PSA-120/120T). The power switch on the back of the FC-200 has three posistions: ON, ECONOMY and OFF. The ON position turns on the power whether you are using batteries or the PSA-120. The ECONOMY position can be selected as an option when batteries are being used. This helps to extend the life of the batteries.
Note: When using Economy mode, the display may flicker or be less bright. This does not affect the operation of the FC-200.
