Changing Switching Regulator unit AC Mains Jumper Wiring

Before attempting this jumper wire change, remove the
AC power cord from the AC jack on the rear panel.
Referring to Figure 1, remove the 14 screws affixing
the top and bottom covers of the repeater, and re-
move the covers.
Remove the eight screws affixing the shield cover
for the FILTER Unit, and remove the cover (see Fig-
ure 1).

Referring to Figure 4, perform the correct jumper
wiring on the Switching Regulator Unit for the AC
Mains voltage used in your area (100-127 VAC or
207-253 VAC).
Replace the heatsink onto the Switching Regulator
Unit, then replace the Switching Regulator Unit onto
the chassis, and connect all wires and connectors to
the FILTER Unit.
Replace the AC fuse (FH6001) on the FILTER Unit
according to the AC Mains voltage range:
100 VAC (100-127 VAC): 5A
200 VAC (207-253 VAC): 3A.
Replace the shield cover and replace the top and
bottom covers. This completes the wiring change.
Important!: If you change the AC voltage range, you
must also change the AC fuse on the FILTER Unit. Do
not replace with a slow-blow type fuse.
