DESCRIPTION
Your
SEARS
849.
62300
Mobile
Stereo
Car-
tridge
Player
is
a
fully-
transistorized
unit
which
will
play
all
presently-
available
eight-
track
stereo
cartridges.
Program
switching
is
fully
automatic,
with
manual
program
change
at
any
time
by
front-
panel
button.
The
high
sound
output
power (
12
watts
peak
total)
will
provide
ample
volume
even
in
converti-
bles,
with
low
battery
drain (
less
than
1
ampere
playing).
Normal
operation
with
precise
governor-
controlled
speed
is
maintained
over
the
full
range
of
battery
voltage (
11-16
volts)
from
a
NEGA-
TIVE-
GROUND
battery
system
only.
OPERATION
Controls
for
your
unit
are
indicated
in
Fig.
1.
Place
the
front
end (
tape
slot)
of
the
cartridge
against
the
cartridge
door
and
insert
the
cartridge
by
pushing
it
straight
into
the
opening
until
program
indicator
lights
up
and
a "
click"
is
heard.
The
unit
is
now
operating
and
sound
can be
adjusted
by
the
VOLUME,
BALANCE,
and
TONE
controls.
The
VOLUME
control
should
be
adjusted
for
comfortable
listening
level.
The
BALANCE
control
should
normally
remain
in
mid
position,
but
may
be
adjusted
as
necessary
to equalize
the
loudness
of
the
sound
coming
from
the
left
and
right
speakers.
The
TONE
control
will
provide
maximum
treble
brilliance
when
turned
fully
rightward
and
maxi-
mum
bass
when
turned
fully
leftward,
and
should
be
adjusted
to
your
individual
taste.

at
any
time.
Pull
the

straight
out
and
the

go
out.
If
a
cartridge
is
left
engaged
in
the
unit
when
power
is
off,
a
flat
spot
will
develop
on
the
pinch
roller in
the
cartridge,
producing
uneven
sound.
NOTE:
When
playing
cartridges
all
four
pro-
gram
indicator
lamps
will
illuminate
in
sequence:
1,
2,
3
and
4.
Due
to the
high
power
capability
of
your
player,
you
may
find that
parts
of
your
vehicle
such
as
in-
struments,
controls,
ash
trays,
and
trim
strips
may
vibrate
and
create
mechanical
noise
at
high
volume
levels.
If this
occurs,
locate
and
tighten
the
offend-
ing
part.

CARE
AND
MAINTENANCE
Tape
Cartridges
The
cartridge
case
is
made
of
high-
impact
plastic
and
should
not
be
exposed
to
heat
exceeding
130
°
F.,
as
this
may
result
in
deforming.
On
the
other
hand,
the
cartridge
should
not
be
left
in
excessive
cold
atmosphere
below
20
°
F.,
as
this
may
make
the
tape
brittle
and
result
in
tape
breakage
during
playback.
If
the
tape
has
been
exposed
to
cold
atmos-
phere,
it
should be used
only
after
leaving
it
in
normal
temperature (
about
70
°
F.),
for
about
15
to
30
minutes.
Never
place
the
tape
in
the
vicinity
of
a
strong
magnetic
field (
such
as
electric
motors,
loud-
speakers,
TV
sets,
radios,
or
other
electrical
appli-
ances)
as
this
may
result
in
erasure
of
the
sound
contained
in
the tape
or
hum
and
noise.
Tape
cartridges
should
be
placed
in
plastic
bags
and
stored
in
places
that
are
not
exposed
to
the
sun: that
are
not
excessively
hot
or
cold:
or
that
do
not
have
excessive
humidity.
This
will
ensure
lasting
satisfaction.
Periodic
Maintenance
This
stereo
tape
player
should be
cleaned
and
lubricated
every
three
months (
or
200
hours
of
use).
This
work
should
be
performed
only
by
a
qualified
service
technician
equipped
with
the
proper
tools
and
instruments.
INSTALLATION
Mounting
the
Unit
The
player
is
furnished
with
newly
designed
two-piece
universal
mounting
brackets
which
can
be
mounted
in
several
different
positions
to
get
optimum
location
and
projection
of
the
unit
out
from
under
the
dash,
or
on
the
floor
or
console
of
any
car,
truck
or boat
with
12
volt
negative
ground
electrical
system. (
Typical
mounting
locations
are
shown
in
Figs.
2
and
3).
Brackets
can be
mounted
with
arms
turned
in
or
out,
right
to
left
or
left
to
right,
so
that
projection
of
the
unit
from mounting
holes
in
its
side
can
be
either
forward
or
rearward
of
the
top
end
of
the
bracket.
For
mounting
under
the
dash,
first
determine
the
most
suitable
location
for
appearance
and
convenience
of
operation
of
the
unit.
Use
the
template
supplied
to
mark
locations
where
the
mounting
holes
are
to
be
drilled.
Always
use
at
least
two
mounting
screws,
and
preferably
three
or
four.
Drill
5/32"
diameter
holes
at
the
marked
locations,
and
fasten
the
brackets
in
place
with
No.
10
self-
tapping
screws (
not
supplied).
Re-
install
the
unit
in
the
mounting
brackets,
selecting
the
appropriate
front
and
rear
mounting
screw
holes
in
the
brackets
and
unit,
to
position
the
unit
at
the
desired
angle (
no more
than
20
degrees
from
horizontal).
Tighten
all
screws
securely.

If
the
mounted
unit
shows
significant
vibration
when
the
vehicle
is
in
motion,
it
will
be
necessary
to
further
support
the
unit
at
the
rear.
This
can
be
done
by
using
the
perforated
support
strap
furnish-
ed.
Install
the
mounting
screw
for
strap (
in
the
mounting
kit)
in
the
tapped
hole
at
the
upper
rear
of
the
unit.
Place
the
end
hole
of
the
strap,
spring
washer
and
hexagonal
nut
onto
the
mounting
screw,
and
tighten
the
nut.
The
strap
should
be
pointing
upward
at
this
time.
Suitably
bend
the
strap
so
that
the
free
end
can
be
attached
to
the
Electrical
Connection

IES.
To
determine
that
your
vehicle
has
the
proper
system,
examine
the
battery.
It
should
appear
as
shown
in
Fig.
4,
with
six
filler
caps.

screw
at
some
point
as
far
as
possible
above
the
unit.
When
installed,
minor
adjustments
of
the
mounting
screw
may
be
necessary
to
ensure
that
this
strap
is
tight
and
is
properly
supporting
the
rear
of
the
unit.
To
mount
the
unit
on
the
floor
or
console
follow
a
procedure
similar
to
that
outlined
above
with
the
arms
of
the
bracket
pointed
upward
as
shown
in
Fig.
3.
The
rear
support
strap
will
not
normally
be
required
for
this
type
of
mounting.
connecting
to
the
vehicle
frame
or
chassis,
the
electrical
system
is
negative
ground
and
is
suitable
for
operation
of
the
player.
Electrical
connections
are
made
as
shown
in
Fig.
5.
The
RED
lead
from
the
fuseholder
should
be
connected
to
the
fuseblock,
ammeter,
or
other
terminal
where
power
is
always
available.
Do
not
connect
to
the
accessory
terminal
of
the
ignition
switch,
since
this
could
result
in
removal
of
power
to
the
unit
when
the
cartridge
is
in
play
position.
Under
this
condition,
a
flat
spot
will
soon
develop
on
the
pinchroller,
producing
uneven
sound.

Loudspeakers
Your
unit
is
designed
to
work
with
speaker
load
impedances
of
2-8
ohms.
Peak
performance
will
result
from
the use
of
matched
sets
of
two
or
four
speakers
of
4
ohm
impedance,
but
essentially
equal
quality
can be
obtained with
two
or
four
8
ohm
units.
Mixing
speakers
of
different
impedance
or
type
can
cause
unbalanced
sound.
NOTE:
POWER

THE
STEREO
UNIT
MUST
BE
REMOVED
DURING

CONNEC-
TION
TO
AVOID
POSSIBLE
DAMAGE
DUE
TO
ACCIDENTAL
SHORTING
OF

LEADS
DURING
THE
INSTALLATION
PRO-
CESS.
You
must
always
install
a
minimum
of
two
speakers,
one
on
the
right
and
the
other
on
the
left,
to
get
the
proper
stereo
effect.
For
the
ultimate
in
stereo
performance,
install
four
speakers,
two
in
front
and
two
in
rear
right
and
left
areas
of
the
car.
Connections
should
be
made
as
shown
in
Fig.

speaker
installations
in
the

will
give
optimum
baffling
for

that
the
tip
of
the

The
following
describes
the
adjusting
procedure
(1)
Adjustment
of
head
height
and
azimuth
re-
quires
the
use
of
special
test
tapes
for
best
result.
Recommended
tapes
are
RCA
No.

for
head
height
and
RCA
No.
326
for
azimuth.

muth
tests,
and
Delco

is
also
suitable
for
both
adjustments.
(2)
Using
an
azimuth
test
tape
producing
a
5000
Hz
or
8000
Hz
signal,
loosen
the
lock
screw
about
1/4
turn.
Turn
the
azimuth
adjusting
screw
for
maxi-
mum
output
as
indicated
by
a
vacuum-
voltmeter
or
an
audio
output
meter
connected
across the
load
resistors
or
appropriate
speaker
leads.
Retighten
the
lock
screw.
(3)
Using
a
medium-
frequency
test
tape (
400'-
3000
Hz)
with
the
signal
recorded
on
one
program
track ( or
one
pair
of
tracks)
with
adjacent
blank
programs
select
the
signal
pro-
gram.
Turn
the
height
adjusting
screw
for
maximum
output.
New
select
the
adjacent
programs (
Nos.
1
and
3
if
the
test
program
is
No.
2)
and
check
that
there
is
no
crosstalk
coming
from
the
No.
2
program
signal.
If
there
is
crosstalk,
make
a
slight
readjustment
of
the
height
screw
to
minimize
crosstalk
on
both
adjacent
program,
at
maximum
volume
setting.
(4)
After
all
adjustments have
been
made,
secure
the
adjusting
screws
with
daubs
of
paint
or
glue.
