Risk of electric shock if the unit is opened.
BSS Audio accepts no responsibility for injury
subsequent to opening of the unit.
A tap change is available on the FDS-388 to allow the unit to work reliably at
mains votages down to 90VAC on the 120V setting and 180VAC on the 240V
setting.
To implement the change proceed as follows:
1 Disconnect mains power and remove the unit's top cover.
2 On the small pcb mounted at the rear of the box on the 120/240V selector
locate the purple and brown wires and reverse their positions. Locate the
orange and yellow wires and reverse their positions. Fuse values do not
change from that required to match the voltage selector. The following
table shows the wire colours referenced to the silk screen labels on the PCB
for both normal and lower voltage applications.
3 Replace the top cover.
WARNING! The maximum mains voltage allowable under these
circumstances is 110VAC for the 120V setting and 220VAC for the 240V
setting
