PREPARING FOR
USE
To
use
your
PR0-16A,
you
must
do
three things:
Connect
power
I nstal I
from
1
to
16 crystals
Connect
an
antenna
To
make a
quick
check,
you
can
just
connect
the
Line
Cord
to
a
source
of
120
volts,
60
Hz,
AC
power.
If
you
intend
to
use
a
12
volt
source,
you
must
connect
the
12
volt
DC
power
plug wires
as
noted
later on
under
"Mobile
Installation".
With
an
antenna connected and a
crystal installed,
turn
the
Receiver on
by
rotating
VOLUME
clockwise. Rotate SOUE LCH
maximum
counterclockwise.
You
should hear a
"rushing"
sound in
the
speaker.
Crystals are
not
included
with
your
PR0-16A
because
the
frequencies
are
so
numerous
. The frequencies used in
your
part
of
the
country
will
be
different
from
those
used
in
other
areas.
Order
the
crystals
you
want
from
your
Radio Shack store- specify
the
model
number
of
this
unit
and
the
frequency
you
want
to
receive.
Remove the
two
Screws
from
the
Crystal
Compartment
Cover
(bottom
of
cabinet)
to
expose
the
crystal sockets and program
switches. Provision
is
made
to
install 16 crystals; the
program
switch
position
can
be
used
to
obtain
either
VHF(L),
VHF(H)
or
UHF
.
For
UHF
crystals,
position
the
program
switch
to
UHF
(Marked
"U"
on
printed
circuit
board).
For
VHF(H),
set
the
program
switch
to
VHF
(Marked
"H"
on
printed
circuit
board).
For
VHF(L),
set
the
program
switch
to
VHF
(Marked
"L"
on
printed
circuit
board).
In
the
example shown channel 1
will
have a
VHF(H)
crystal and
channel 9
will
have a
UHF
crystal.
NOTE:
If
you
have a channel
that
you
are
particularly
interested in,
put
the
crystal
for
that
channel
into
Channel 1
position
(
PRIORITY
). Refer
to
OPERATION
section
for
details on
the
function
of
PRIORITY.

Ask
the
manager
of

He
will
be
glad to advise
you.
Since crystal frequencies must
be
extremely
accurate and crystals
should
be
matched
for
specific
units,
we recommend
you
obtain
crystals
for
your
Receiver
onl
y
from
Radio Shack.
We

not

for
the
poor
or
improper
operat

of
crystals
from
another
manufacturer(s).
