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.
r Referring to Figure 1, remove the 14 screws affixing
the top and bottom covers of the repeater, and re-
move the covers.
r Remove the eight screws affixing the shield cover
for the FILTER Unit, and remove the cover (see Fig-
ure 1).
r Disconnect all wires and connectors from the FIL-
TER Unit, then remove the six screws affixing the
Switching Regulator Unit, and remove it (the Switch-
ing Regulator Unit is mounted with the FILTER Unit:

r 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).
r 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.
r 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.
r 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.
