GENERAL
DESCRIPTION
The
TV
50,
90
and 120
series
monitor
is
a
raster
scan
display
designed
speci-
fically
for
data
terminals.
They
are
designed
for
high
quality
display
of
alpha-
numeric
dot
characters.
The
data
monitor
accepts
video,
horizontal
drive
and
vertical
drive
as
separate
TTL
level
signals,
eliminating
stripping
circuits
in
the
data
display
unit
as
well
as
mixing
circuits
in
the
external
logic
interface.
The
100%
solid
state
silicon
circuitry
of
the
PWA
provides
cool
operation
and
high
reliability.
The
electronic
package.has
been
miniaturized
for

HUMAN
FACTORS
SPECIFICATION
X-Ray
Radiation
The
TV
50,
90
and 120
Data
monitor
complies
with
the
Federal
Regulation
for
Radiation
Control
as
required
by
the
Radiation
Control
for
Health
and
Safety
Act
of
1968, and
as
implemented by
Title
21,
Subchapter
J
of
the
Code
of
Federal
Regulation.
These
regulations
place
certain
requirements
upon
manufacturers
of
products
which
can
emit
x-rays
under
some
conditions
of
operation
or
failure.
This
in-
cludes
CRT
data
display
monitors.
Label
Visibility
Certification
of
compliance
with
radiation
regulations
is
shown by a
label
attached
to
each
monitor.
The
user
is
responsible
for
labeling
his
product
in
a
similar
fashion
or
in
making
the
DHEW
label
easily
visible
from
the
outside
of
the
enclosure.
The
regulations
state
that
"This
(certification)
information
shall
be
provided
in
the
form
of
a
tag
or
label
permanently
affixed
or
inscribed
on
such
product
so
as
to
be
legible
and
readily
accessible
to
view when
the
pro-
duct
is
fully
assembled
for
use
...
" Each
monitor
is
supplied
with
an
extra
label
attached
to
the
face
of
the
CRT.
The
user
will
remove
this
label
and
use
it
as
stated
above.
Power
Requirements
The
Data
monitor
is
designed
to
operate
and meet
radiation
requirements
when
operated
within
the
respective
AC
or
DC
input
power
specifications.
Radiation
testing
is
performed
at
the
maximum
specified
input
voltage
for
AC
powered
mon-
itors
or
at
130
VAC
for
those
nominally
powered
at
110-120
VAC,
60 Hz.
DC
powered
monitors
have
an
additional
requirement
because
the
DC
source
is
usually
regulated
and
subject
to
failure
of
the
series
pass
element.
This
can
result
in
an
appreciable
increase
in
the
anode
voltage
and
consequent
emission
of
x-rays.
This
is
not
a problem
for
monitors
equipped
with
over
voltage
pro-
tection.
For
monitors
not
so
equipped,
it
is
necessary
for
the
buyer
to
ensure
that
the
normal
adjustment
of
his
regulator
does
not
exceed
the
maximum
level
specified
for
the
particular
monitor.
Furthermore,
he
shall
ensure
that
the
maximum
available
voltage
from
the
supply
cannot
exceed
1.33
times
nominal mon-
itor
input
when
the
supply
has
a
single
failure
such
as
to
cause
the
highest
possible
output
voltage.

GROUNDING
TECHINIQUES
The method
of
interconnecting
and grounding
the
equipment
is
a
function·
of
the
signal
frequency.
Optimum
grounding depends
largely
on
the
system
in
which
the
equipment
is
used.
The
following
grounding
technique
is
recommended
when
instal-
ling
the
monitor.
Refer
to
figure

for
interface
connections.
The
horizontal,
CRT
arc
and

A
connection
to
system
ground must
be
made
at
both
JlOl-l
and
JlOl-lO.
When
the
frame
is
an
integral
part
of
system
ground,
one
of
three
possible
ground
config-
urations
can
be
used.
1.
When
a good
electrical
ground
connection
cannot
be
made
between
the
monitor
frame and
system
ground,
then
JlOl-l
and
JlOl-lO
is
wired
separately
to
the
system
ground.
2.
When
a good ground
connection
can
be
made
between
the
monitor
frame and
system
ground,
then
JlOl-lO
is
wired
to
the
system
ground and
JlOl-l
is
left
open.
3.
When
the
ground
connection
between
the
monitor
frame and
the
system
ground
is
acceptable
and
it
is
desired
to
omit
the
wire
from
JlOl-lO,
then
add a jumper
wire
to
the
board
to
connect
JlOl-5
and
JlOl-lO
to-
gether.
JlOl-5
is
then
wired
to
the
system
ground.
The
monitor
is
normally
supplied
without
the
jumper
wire
from
JlOl-5
to
JIOl-lO
to
prevent
horizontal
circuit
ground
currents
from
flowing
in
the
video
ground
circuit.
In
cases
of
severe
arc
related
problems,
the
jumper between
JlOI-1
and
JlOl-5
can
be removed and
JlOI-5
or
EllO
can
be
connected
separately
to
the
frame
or
CRT
aquadag
ground.
JIOl-l
or
El02 must
then
be
connected
either
to
the
frame
or
system
ground.
To
isolate
the
frame from
system
ground,
JlOI-1
and
JlOI-IO
should
be
wired
separately
to
system
ground.
Add
another
wire
to
JlOI-l
and
connect
it
and
JlOl-5
to
the
frame (aquadag ground)
through
a
capacitor.
The frame
cannot
be
completely
isolated,
since
an
AC
connection
between
the
signal
ground and frame must
be
maintained
to
assume a
complete
circuit
for
the
CRT
aquadag
capacity.
When
the
video
is
routed
in
by a
long
cabling,
shielded
cable
should
be
used.
To
avoid
a ground
loop,
only
one end
of
the
shield
should
be
grounded.
2.5
INPUT SIGNAL
LEAD
ROUTING
The
input
signal
leads
probably
will
carry
high
frequency
signals
and
should
be
given
the
following
considerations:
A.
To
minimize
distributed
capacity
and
capacitive
pickup
of
nearby
radiated
fields,
route
the
video
leads
separately
and away from
all
other
wiring.
B.
Make
the
lead
length
as
short
as
possible,
consistent
with
the
packaging
requirements.
C.
Ideally,
the
video
line
should
meet
the
requirements
of
a
terminated
coaxial
system;
i.e.,
the
video
line
should
exhibit
a
constant
impedance
from
source
load.

OPERATION
3.1
GENERAL
After
power,
video
and
drive
signals
have
been
applied
to
the
monitor,
the
con-
trast
and
brightness
controls
may
be
adjusted
to
provide
the
optimum
display.
3.2
BRIGHTNESS ADJUST
The
monitor
is
used
to
display
alphanumeric
information.
The
video
polarity
is
usually
white
characters
on a
black
background.
The
brightness
control
should
then
be
adjusted
for
visual
cutoff
of
the
raster.
A
maximum
contrast
ratio
can
now
be
obtained
when
video
is
applied.
3.3
CONTRAST
ADJUST
The
video
amplifier
is
designed
to
operate
linearly
from
+.65
to
+2.5 V
signal
input.
The
contrast
control
should
be
adjusted
to
the
point
where
defocusing
sets
in
and
then
backed
down
slightly.
This
occurs
at
a lS-20V
p-p
video
swing
at
the
CRT
cathode
for
the
TV90/l20, and
at
a
l2-lSV
p-p
swing
for
the
TVSO.
In
no
case
should
contrast
be
adjusted
to
cause
saturation
of
QlOl,
as
this
im-
pairs
the
pulse
response
of
the
video
amplifier.

THEORY
OF
OPERATION
4.1
VIDEO AMPLIFIER
The
video
amplifier
consists
of
QlOl and
its
associated
circuitry.
The incoming
video
signal
is
applied
to
the
monitor
through
JlOl-8
and RlOl
to
the
base
of
QlOl.
Transistor
QlOl
has
a nominal
gain
of
15,
and
operates
as
a
class
B
amplifier.
QlOl
remains
cutoff
until
a
DC
coupled,
positive-going
signal
arrives
at
its
base
and
turns
it
on.
Rl03
provides
series
feedback
which makes
the
terminal
to
terminal
voltage
gain
relatively
independent
of
transistor
parameters
and
temperature
variations.
RI02 and CIOI
provide
emitter
peaking
to
extend
the
bandwidth
to
12~1Hz.
.
The
negative
going
signal
at
the
collector
of
QIOI
is
direct
coupled
to
the
CRT
cathode.
The
class
B
biasing
of
QIOI
allows
a
large
video
output
signal
to
modulate
the
CRT's
cathode
and
results
in
a
maximum
available
contrast
ratio.
The
overall
brightness
at
the
screen
of
the
CRT
is
also
determined
by
the
neg-
ative
potential
at
its
grid
which
is
varied
by
the
brightness
control:
4.2
VERTICAL DEFLECTION
QI02
is
a
thyristor
used
as
programmable
unijunction
and
together
with
its
ex-
ternal
circuitry
forms a
relaxation
oscillator
operating
at
a
vertical
rate.
The
sawtooth
forming network
consists
of
AIOI, Cl03 and
Cl04.
These
capacitors
charge
exponentially
until
the
voltage
at
the
anode
of
Ql02
exceeds
its
gate
voltage
at
which
time
QI02 becomes
essentially
a
closed
switch,
allowing
a
rapid
discharge
through
LIOI. The
rate
of
charge
or
frequency
is
adjustable
by
AIOI. The
oscillator
is
synchronized
by a
negative
pulse
coupled
to
its
gate
from
the
vertical
drive
pulse
applied
externally
at
JIOI-9.
A
divider
network
internal
to
AIOI
sets
the
free
running
frequency
by
establish-
ing
a
reference
voltage
at
the
gate.
This
programs
the
firing
of
QI02 and
amounts
to
resistive
selection
of
the
intrinsic
standoff
ratio.
The
frequency
is
controlled
by
passive
components
only.
CRIOI
provides
temperature
com-
pensation
for
Ql02
while
controlling
the
gate
impedance
to
allow
easy
turn
on
and
off
of
QI02. LIOI forms a
tuned
circuit
with
Cl03 and Cl04
during
conduction
of
QI02 which
provides
a
stable
control
on
the
drop-out
time
of
QI02
to
assist
in
maintaining
interlace.
Ql03
collector
to
base
forward
diode
clamping
action
prevents
the
voltage
from
swinging
too
far
negative
during
this
flywheel
action.
The
sawtooth
at
the
anode
of
Ql02
is
direct
coupled
to
the
base
of
Ql03.
This
stage
functions
as
a
darlington
pair
emitter
follower
driver
for
the
output
stage
QI04.
It
presents
an
extremely
high
impedance
in
shunt
with
AlOI and
prevents
the
Beta
dependent
input
impedance
of
QI04 from
affecting
the
frequency
of
the
4-1
IMl03S
sawtooth
forming
network.
Linearity
control
of
the
sawtooth
is
accomplished
by
coupling
the
output
at
Ql03
emitter
resistively
back
into
the
junction
of
Cl03 and Cl04.
This
pro-
vides
integration
of
the
sawtooth
and
inserts
a
parabolic
component. The
slope
change
rate
of
the
sawtooth
at
Ql03
output
is
controlled
by
the
setting
of
Al02. The
output
at
Ql03
is
coupled
into
a
resistive
divider
..
Height
control
RllO
varies
the
amplitude
of
the
sawtooth
voltage
applied
to
the
base
of
Ql04 and
controls
the
vertical
raster
size
on
the
CRT.
CIOS
is
used
to
limit
the
amplitude
of
the
flyback
pulse
at
Ql04
collector.
The
vertical
output
stage
Ql04
uses
an
NPN
power
transistor
operating
as
a
class
AB
amplifier.
The
output
is
capacitively
coupled
to
the
yoke. Ll
pro-
vides
a
DC
connection
to
B+
for
Ql04;
it
has
a
high
impedance compared
to
the
yoke
inductance
which
causes
most
of
the
sawtooth
current
of
Ql04
to
appear
in
the
yoke. Rl14
prevents
oscillations
by
providing
damping
across
the
vertical
yoke
coils.
4.3
HORIZONTAL
DEFLECTION
4.3.1
Low
Level
Stages
(Figure
4-1)
The
purpose
of
QlOS
and Ql06
is
basically
to
process
the
incoming
horizontal
drive
signal
into
a form
suitable
to
drive
the
output
stage
Q108.
The
duty
cycle
of
Q108
becomes
essentially
independent
of
the
amplitude
and
pulse
width
of
the
drive
pulse.
This
is
a
necessary
condition
to
assure
stability
and
reliability
in
the
output
stage.
In
adddition,
these
stages
provide
a
horizontal
video
centering
adjustment
by
delaying
retrace
with
respect
to
the
horizontal
drive
pulse.
The
drive
pulse
is
presented
to
Q10S
via
J10l-6.
The
base
circuit
of
QlOS
in-
cludes
a clamp and a
differentiator
which makes
Q10S
output
insensitive
to
drive
pulse
amplitude
and
width
changes.
The
only
requirement
is
that
pulse
amplitude
be
of
2.S
volts
minimum
and
pulse
width
should
be
lO-40~s.
QlOS
together
with
Ql06
functions
as
a monostab1e
multivibrator
with
Ql07
being
a
slave
that
pro-
vides
a
positive
feedback.
Specifically,
when
Q10S
is
turned
on by
the
drive
pulse,
it
discharges
Cl12
at
a
rate
determined
by
the
setting
of
Al03.
When
Cl12
is
discharged
to
2.7S
volts,
Q106
turns
off.
This
change
of
state
turns
Ql07 on and
the
base
drive
to
Ql06 from
R128
is
shunted
thru
Ql07. QI06/Q107
remains
in
this
state
for
nominally
2S~s
until
Cl12
recharges
through
Al03
to
8.2S
volts.
At
this
time,
Q106
is
biased
on
again
by
the
current
through
Al03.
The
mu1tivibrator
is
now
in
a
state
that
Q106
is
on and Q10S/Q107
is
off.
It
will
remain
in
this
state
until
the
next
drive
pulse
occurs
or
power
is
turned
off.
Cl12
is
the
only
timing
capacitor
in
the
circuit
and
has
two
time
constants
associated
with
it.
Primarily,
the
charge
path
between
pin
1 and
pin
3
of
Al03
determines
the
on
time
of
Q107
while
the
discharge
path
through
the
video
center-
ing
control
and
QlOS
determines
the
delay
between
application
of
the
drive
pulse
and
start
of
retrace
(turn
on
of
Ql07).

Ql07
is
an
inverting
slave
of
QI06 and
is
driven
alter-
nately
into
saturation
and
cutoff
as
are
all
stages
in
the
horizontal
circuit.
Ql07
output
is
transformer
coupled
to
the
output
stage
with
phasing
of
TlOl
chosen
such
that
Ql08
turns
off
when
Ql07
turns
on.
This
allows
Ql08
to
turn
off
quickly,
thus
minimizing
dissipation.
A
careful
review
will
show
that
Ql08
turns
off
at
a
variable
delay
time
after
receipt
of
the
drive
pulse.
This
action
causes
retrace
to
begin.
During
conduction
of
the
driver
transistor,
energy
is
stored
in
the
coupling
transformer.
The
polarity
at
the
secondary
is
then
phased
to
keep Ql08
cut
off.
As
soon
as
the
primary
current
of
TlOl
is
interrupted
due
to
the
base
signal
driving
Ql07
into
cut
off,
the
secondary
voltage
changes
polarity.
Ql08
now
saturates
due
to
the
forward
base
current
flow.
This
gradually
decreases
at
a
rate
deter-
mined by
the
transformer
inductance
and
circuit
resistance.
However
the
base
current
is
sufficient
to
keep Ql08
in
saturation
until
the
next
polarity
change
of
TlOl.
The
horizontal
output
stage
has
two main
functions:
1)
to
supply
the
deflection
coil
with
the
correct
horizontal
scanning
currents:
2)
to
develop
high
voltage
for
the
CRT
anode and
DC
voltage
for
the
CRT
bias,
focus
and
accelerating
grids
as
well
as
the
DC
voltage
for
the
video
output
stage.
(
Ql08
acts
as
a
switch
which
is
turned
on
or
off
by
the
rectangular
waveform on
the
base.
When
it
is
turned
on,
the
supply
voltage
plus
the
charge
on
C123
causes
deflection
current
to
increase
in
a
linear
manner and moves
the
beam
from
near
the
center
of
the
screen
to
the
right
side.
At
this
time,
the
transistor
is
turned
off
by a
polarity
change
of
TlOl which
causes
the
output
circuit
to
oscillate.
A
high
reactive
voltage
in
the
form
of
a
half
cycle
negative
voltage
pulse
is
developed
by
the
deflection
coil
inductance
and
the
primary
of
T2.
The peak
magnetic
energy
which
was
stored
in
the
deflection
coil
during
scan
time
is
not
transferred
to
Cl22 and
the
deflection
coil
distributed
capacity.
During
this
cycle,
the
beam
is
returned
to
the
center
of
the
screen.
The
charged
capacitances
now
discharge
into
the
deflection
coil
and
induce
a
current
in
a
direction
opposite
to
the
current
of
the
previous
part
of
the
cycle.
The
magnetic
field
thus
created
around
the
coil
moves
the
·scanning
beam
to
the
left
of
the
screen.
After
slightly
less
than
half
a
cycle,
the
decreasing
voltage
across
Cl22
biases
the
damper
diode
CRIll
into
conduction
and
prevents
the
flyback
pulse
from
fur-
ther
oscillation.
The
magnetic
energy
that
was
stored
in
the
deflection
coil
from
the
discharge
of
the
distributed
capacity
is
now
released
to
provide
sweep
for
the
left
half
of
scan
and
to
charge
Cl23
through
the
rectifying
action
of
the
damper
diode.
The
beam
is
now
at
the
center
of
the
screen.
The
cycle
will
repeat
as
soon
as
the
base
of
QI08 becomes
positive
with
respect
to
its
emitter.
e123
serves
to
block
DC
current
from
the
deflection
coil
and
to
provide
"S"
shaping
of
the
current
waveform. "S"
shaping
compensates
for
stretching
at
the
left
and
right
sides
of
the
picture
tube
because
the
curvature
of
the
CRT
face
and
the
deflected
beam
do
not
follow
the
same
arc.
LI03
is
an
adjustable
width
control
placed
in
a
series
with
the
horizontal
de-
4-4
IM1035
flection
coils.
The
variable
inductance
allows
a
greater
or
lesser
amount
of
de-
flection
current
to
flow
through
the
horizontal
yoke and
varies
the
width
of
the
horizontal
scan.
Linearity
control
is
provided
by
modifying
the
deflection
coil
voltage.
During
retrace,
an
auxi11iary
winding on
the
f1yback
transformer
supplies
a
pulse
which
charges
Cl19
through
rectifier
diode
CRl12 and L102.
This
voltage
is
then
applied
in
series
with
the
deflection
coil
when
the
damper
diode
turns
on
at
the
start
of
trace.
The
voltage
is
sawtooth
shaped
and
has
the
effect
of
decreasing
the
deflection
coil
current
as
a
function
of
the
sawtooth
shape.
This
compensates
for
the
stretch
normally
found on
the
left
side
of
the
screen
due
to
the
deflec-
tion
coil
and
system
RL
time
constant.
Linearity
is
optimized
by
adjustment
of
L102
which
acts
as
an impedance
to
the
pulse
from T2.
The
negative
f1yback
pulse
developed
during
horizontal
retrace
time
is
rectified
by
CR110
and
filtered
by C117.
This
produces
approximately
-130
VDC
which
is
coupled
through
the
brightness
control
Rl17
to
G1
of
the
CRT.
This
same
pulse
is
transformer-coupled
to
the
secondary
of
T2
where
it
is
rectified
by
CR2,
CRl13 and
CR114
to
produce
rectified
voltage
of
approximately
l2KV,
400V
and
32V
respectively.
l2KV
is
the
anode
voltage
for
the
CRT,
while
32V
is
used
for
the
video
output
stage,
and
the
400V
source
is
used
for
G2
and
G4
voltages
for
the
CRT.
4.4
LOW
VOLTAGE
SUPPLY
The
TV
90/120
models
are
available
with
an
internal
power
supply.
This
supply
utilizes
an
integrated
circuit
voltage
regulator
which
supplies
15VDC±2.5%
to
J103-1.
It
also
supplies
12.6
VAC
to
J103-3
and 4
for
the
CRT
filament.
The
l20VAC
primary
voltage
(220/240V
optional)
is
stepped
down
at
the
secondary
of
T1
where
it
is
rectified
by
CRI
and
filtered
by
CI.
A2
functions
as
a
series
regulator
to
drop
the
rectified
voltage
down
to
l5V
at
pin
2.
The
regulator
maintains
a
constant
output
voltage
(within
2.5%)
with
changes
in
line
voltage
load.or
temperature.
It
is
capable
of
supplying
1.5
amps
and
features
internal
current
limiting,
thermal
shutdown and
safe
over-voltage
protection.
A
hermetically
sealed
TO-3
case
is
used
for
high
reliability
and low
thermal
re-
sistance.
If
a
short
circuit
is
present
at
the
output,
the
current
limiting
feature
of
A2
will
cause
the
output
current
to
fold
back
to
safe
levels.
The
fast
limiting
action
of
A2
is
very
effective
in
protecting
transistors
from abnormal
loads.
The
resistor
Rl,
is
used
to
reduce
the
power
dissipation
in
A2.

ADJUSTMENT
AND
MAINTENANCE
5.1
HORIZONTAL
ADJUSTMENTS
With a
crosshatch
signal
applied,
adjust
video
centering
control,
Al03
to
center
the
video
within
the
raster
horizontally.
Adjust
Ll02
for
best
horizontal
lin-
earity.
Do
not
adjust
Ll02
core
out
farther
than
necessary
as
this
causes
ex-
cessive
power
to
be consumed.
Adjust
Ll03
for
desired
width.
5.2
VERTICAL
ADJUSTMENTS
With
the
crosshatch
signal
applied,
adjust
vertical
hold
control
AlOl
to
lock
in
the
picture.
Adjust
vertical
linearity
control
Al02
for
best
overall
linearity.
This
control
affects
the
vertical
frequency
slightly
and might
require
a
readjustment
of
the
hold
control.
Adjust
vertical
height
control
RllO
for
desired
height.
5.3
FOCUS
ADJUST
Adjust
focus
control
R122
for
best
overall
focus
of
the
picture.
Usually
the
center
and
corners
of
the
screen
do
not
focus
at
the
same
setting
and a compromise
must be made.
5.4
CENTERING ADJUST
If
the
raster
is
not
properly
centered,
it
may
be
repositioned
by
rotating
the
ring
magnets
behind
the
deflection
yoke. The
ring
magnets
should
not
be
used
to
offset
the
raster
from
its
nominal
center
position
because
this
degrades
the
focus
and
resolution
of
the
display
and
may
cause
neck
shadow.
If
the
picture
is
tilted,
rotate
the
entire
yoke.

GENERAL
We
are
continually
striving
to
provide
you

manual
that
represents
the

you have
ordered.
Because
of
printing
and
shipping
requirements
we
can't
get
these
changes
immediately
in
to
the
printed
manuals.
This
section
will
contain
change
information
concerning
the
TV
50,
90,
120
data
display
models.
Each change
supplement
section
will
identify
the
mode1(s)
affected
by
revision
level
of
the
final
assembly.
Section
1
through
6
represents
the
TV
50,
TV
90
and
TV

at
the
B reV1Slon
level.
The
revision
level
of
your

can
be
identified
by
the
revision
letter

LOST
OR
DAMAGED EQUIPMENT
The goods described on your Packing Slip
have
been
received by the Transportation Company com-
plete
and
in good condition.
If
any
of
the goods called
for
on this Packing Slip
are
short or damaged,
you must file a claim WITH THE TRANSPORTATION COMPANY FOR THE AMOUNT OF THE
DAMAGE
AND/OR
LOSS.
IF
LOSS
OR
DAMAGE
IS
EVIDENT
AT
TIME
OF
DELIVERY:
If
any
of
the good called
for
on
th
is
Packing
SI
ip
are
short
or
damaged
at the time
of
delivery, ACCEPT THEM,
but
only
if
the Freight Agent makes a
damaged
or
short
notation on
your
Freight Bill or Express Receipt
and
signs
it.
IF
DAMAGE
OR
LOSS
IS
CONCEALED
AND
DISCOVERED
AT
A LATER
DATE:
If
any concealed
loss
or
damage
is
discovered,
notify
your
local Freight Agent
or
Ex-
press
Agent
AT
ONCE
and
request him
to
make an inspection. This
is
absolutely
necessary.
Unless
you do this, the Transportation Company
will
not consider any
claim
for
loss
or
damage
valid.
If
the agent
refuses
to
make
an
inspection, you
should draw up
an
affidavit
to
the effect that you notified him on a certain date and
that
he
failed
to
make the
necessary
inspecV-on.
After
you
have
ascertained the extent
of
the
loss
or
damage,
ORDER THE REPLACEMENT
PARTS
OF
COMPLETE
NEW
UNITS FROM THE FACTORY.
We
will
ship
to
you and
bill
you
for
the cost. This new invoice will then
be
a part
of
your
claim
for
reimbursement from the Transporta-
tion Company. This, together
with
other
papers,
will
properly support
your
claim.
Remember,
it
is
extremely important that you do
not
give the Transportation Company a clear
re-
ceipt
if
damage
or shortages
are
evident upon delivery.
It
is
equally important that you call
for
an
inspection
if
the
loss
or
damage
is
discovered later. DO NOT, UNDER
ANY
CIRCUMSTANCES,
ORDER THE TRANSPORTATION COMPANY TO RETURN SHIPMENT TO OUR FACTORY
OR REFUSE SHIPMENT
UNTIL
WE
HAVE
AUTHORIZED
SUCH RETURN.
IMPORTANT

Be
sure
a declared value equal
to
the price
of
the

is
shown on the bill

is
applicable. This would cover claim
for
shipping dam-
age
on return.

Under this warranty, Ball Electronic Display Division

in the field. The components
will

cancelled upon receipt
of
the defective components at the factory. When
ordering components
for
repair
or
replacement, the model number

cluded on the customer request.

stallation or application, alteration
