Changing Power Transformer
AC
Mains Wiring
Before attempting this wiring change, re-
move the AC
power
cord from the rear panel
jack.
o Remove the four screws affixing the top
cover
of
the
repeater,
and
remove the
cover.
o Note the location of the AC fuse, and the
three screws affixing the clear protective
plastic sheet to the repeater (one screw
near the fuse block,
and
two
on
the
PA
Unit).
o Remove the four screws and the plastic
sheet.
o Referring to the diagram below, determine
the correct transformer
primary
jumper
wiring for the AC Mains voltage
used
in
your area.
o Next, using a
medium
power
(approx. 30-
watt) soldering iron, rewire the jumpers
according to the diagram.
o
If
necessary, replace the AC fuse according
to the AC Mains voltage range:
100-117-V
AC:
SA
200-234-V AC: 3A
o Replace
the
clear protective
sheet
and
cover, this completes the wiring change.

Important!
If
you
change
the
AC
voltage range,
you
must
also
change
the
rear-panel
ACjitse. Do
not
replace
with
a slow-blow type
fuse. Also make sure the
voltage marking
on
the
rear-panel label matches
the
new
voltage setting.

Caution!
To
avoid
blowing
the
rear-panel
AC
fuse,
wait
at
least
30
seconds
after
un-plugging
the
repeater
AC
power
cord
before
plugging
it
in
again.
This
allows
the
DC
power
supply
capacitor-bank
residual
voltage
to
bleed
down,
and
prevent
a
high
start-up
current
when
power
is
reapplied.
