INSTALLATION
GENERAL
Carefully remove
the
FR-101 receiver from
the
carton
and examine
it
for any physical damage. Should any be
apparent,
notify
the
carrier immediately, stating the
damage in detail. Save
the
carton
and packing materials
for future use.
LOCATION
In
general,
the
location
of
the
FR-101
is
not
critical,
however it
is
recommended
that
excessively warm
locations be avoided. The FR-101 should be placed in a
location
that
has adequate space
to
permit free air
circulation through
the
cabinet opening.
POWER REQUIREMENT
Two prewired plugs are furnished
with
the
unit
for
AC
or
DC
voltage
operation.
The FR-101
is
supplied
with
a
multi-voltage power transformer and can be
operated
in
many areas
of
the
world where voltages
may
differ from
your
local supply voltage. Therefore, before connecting
the
AC
cord
to
the power
outlet,
be sure
that
the
voltage
marked on
the
rear
of
the
receiver agrees
with
the
local
AC
supply voltage.
CAUTION
PERMANENT DAMAGE WILL RESULT IF
IM-
PROPER
AC
SUPPLY VOLTA<:;E IS APPLIED TO THE
RECEIVER.
The FR-101 will
operate
satisfactorily from 12 volt,
negative ground
battery
source
by
connecting
the
DC
power cord
to
the
rear panel receptacle. The receiver
requires an average
of
0.5 amp. When making connec-
tions to
the
battery,
be certain
that
the
RED lead
is
connected
to
the positive ( +) and
the
BLACK lead
to
the
negative (- ) terminals
of
the
battery.
Reversed connec-
tion could
permanently
damage
the
receiver circuitry.
ANTENNA AND GROUND
The FR-101
is
designed
for
use
with
a resonant
antenna
at
the
operating frequency
and
having an impedance
of
50
to
75 ohms. This requirement
is
easily
met
by
using a
center-fed dipole
antenna
resonated to
the
receiving
frequency and fed with coaxial cable.
For
amateur
band
operation,
any commercially designed
antenna
system
with
an impedance
of
50
to 75 ohms
may
be used.
Jf a
tuned,
open-wire transmission line
or
a long wire
antenna
is
used, a suitable
antenna
tuner
must be used
between
the
receiver and
antenna.
For
more detailed
description on antennas, please refer
to
"The
ARRL
Antenna
Hand
Book"
or
"The
Radio
Amateur
Hand
Book".
It
is
recommended
to
use
the
transmitting
antenna
when
the
FR-101
is
used
with
a transmitter
or
a transceiver.
Antenna
change-over
is
accomplished
by
an antenna
relay provided in our transmitter
or
transceiver.
The FR-101 should be connected t8 a good ground. The
ground lead should be connected to
the
terminal marked
GND located
on
the rear panel
of
the
receiver.
SPEAKER
A 4
ohm
speaker should be connected to the jack on
the
rear
of
the
chassis marked SP. One lead
of
the speaker
output
is
grounded to
the
chassis
so
that
the one lead
of
the speaker should be connected
as
illustrated
in
Figure
2.
Our accessory speaker model SP-10 l B/
2778
or
SP-1
O l PB/277PB provides
the
correct impedance match
and matches in appearance with the FR-I 01.
HEADPHONE (
4 to 8
ohm
impedance)
A headphone jack
is
provided ·on
the
front panel for the
use
of
a high sensitivity headphone. When a low
sensitivity headphone
is
used, the 100 ohm resistor,
RI I, should
be
shorted for adequate volume. (Ref. to
Fig.
I)
MUTE
The MUTE
jack
on
the
rear
of
the chassis
is
wired
so
that
the
receiver will operate only when
the
inner-
conductor
of
this
jack
is
shorted
to
ground. When the
FR-101
is
operated
separately, and external muting
is
not
desired,
the
RCA plug
with
shorted inner and
outer
conductors
should be inserted
into
the MUTE jack. The
inner-conductor should, therefore, be connected to a
relay contact in
the
transmitter,
or
the transceiver,
which
is
normally
open
in transmit and grounded in
receive.
It
is
recommended
that
a shielded wire be used
for the interconnection between
the
transmitter or
transceiver.
