W98
and
W99
jumper
wires
on
the
MAIN
unit
must
be
changed
as
shown
in
the
diagram on
page
45.
4)
The FL-70
and
the
CFJ455K5
can
now
be
selected
by
pushing
the
FILTER SWITCH
on
the front panel
IN.
The
receive
bandwidth
will
be 2.8kHz.
The FL-80 and FL-44A
can be
selected
by
placing the
FILTER SWITCH
at the
OUT
position.
The
bandwidth
will
then be 2.3kHz.
This
is
a
9MHz
filter
for the
AM
mode. The
filter replaces the
FL-32A
and
requires the
relocation of
jumper
wires.
1)
Use the
FL-63A
installation
method
given previously.
Install
where
the
FL-32A
is
now
installed.
2)
Change
the
jumper
wires
as
shown
in
the diagram.
3)
This installation causes the
FL-33
to be selected whether
the
FILTER SWITCH
is
at
the IN or
OUT
position
when
using the
AM
mode. Only
455kHz
filters will
be changed by
the
FILTER
SWITCH.
WARNING:
Disconnect the
power
cable
from
the
IC-751A
before
performing any work.
1)
Turn
the
transceiver
upside
down. Remove
PLATE
(A) attached
to the rear panel
by unscrewing the four screws. These
screws
will
be used
later.
2)
Attach the IC-PS35 to the
bottom
cover with the supplied screws
and
insulating washers.
Also
insert
the
insulating gasket
between
the
IC-PS35 and the
bottom
cover.
3) Pass the
DC
power
cable
attached to PI through the hole of the
AC
power
socket
plate as
shown
in
the
illustration,
then
insert
the bushing
into
the
hole.
Attach
the
AC
power
socket
plate
to the
PLATE
(A) position
using
the screws
which
previously held
PLATE
(A).
The
AC
power
socket should be
towards
the
bottom
of the transceiver.
4) Pass the P2'
connector from
the
power
socket
unit to the inner
chassis
through the hole
in
the
rear chassis.
Connect
this
P2'
connector with the
P2 connector from the IC-PS35.
5)
Position the cables
in
the rear chassis. This prevents
magnetic
coupling
between the cables
and
the
VCO
coil cores.
6)
Replace the top
and bottom
covers of the transceiver.
Plug PI
from
the IC-PS35
into
the
DC
Power Socket on
the transceiver.
7)
Connect the supplied
AC
power
cable into
the newly
installed
AC
power
socket
on
the
rear
panel of the
IC-751A. Connect
the
AC
power
plug
into
an
AC
power
outlet.
8)
Push the
IC-751A
POWER
SWITCH
to apply
power
to the
transceiver.
