CONNECTING THE MONITOR TO A COMPUTER
The monitor connection cable connects your monitor
to
a Com-
modore personal computer. Before you connect the cable, turn off
the power to both your personal computer and the monitor.
There are two different cables that you can use
to
connect the
monitor to your computer.
1.
One kind of cable has three jacks that connect
to
the BACK of
the monitor.
2.
The other cable has two jacks that connect to the FRONT of the
monitor.
The kind of cable you'll use depends on your computer.
To
find
out which kind
of
cable you should use, look at the audio/video
connector on your computer
(see
your computer's user manual
if
you don't know where this connector
is).
1.
If the audio/video connector has EIGHT little holes, use the
three-jack cable.
2.
If the connector has FIVE little holes, use the two-jack cable.

SAFETY PRECAUTIONS
Electrical energy can perform many useful functions. This
unit
has been engineered and manufactured to assure your personal
safety. But improper use can result
in
potential electrical shock
or
fire hazards. In order not
to
defeat the safeguards incorporated in
this monitor, observe the following basic rules
for
its
installation,
use and servicing. And also follow all warnings and instructions
marked on your video monitor.
INSTALLATION
1.
Your set is equipped
with
a polarized AC line plug (one blade
of
the plug is wider than the other).
This safety feature allows the plug
to
fit
into
the power outlet
only one way. Should you be unable to insert the plug fully
into
the outlet, try reversing the plug. Should
it
still fail
to
fit, con-
tact your electrician.
2.
Operate the set only from a power source as indicated on the
set
or
refer
to
the user's manual
for
this information. If you are
not sure
of
the type
of
power supply
to
your home, consult
your dealer
or
local power company.
3.
Overloaded AC outlets and extension cords are dangerous,
and so are frayed power cords and broken plugs. They may
result in a shock
or
fire hazard. Call your service technician for
replacement.
4.
Do not allow anything
to
rest
or
roll over the power cord, and
do
not place the set where power cord is subject
to
traffic
or
abuse. This may result in a shock
or
fire hazard.
5.
Do not use this set near water -
for
example, near a bathtub,
washbowl, kitchen sink,
or
laundry tub, in a wet basement,
or
near a swimming pool, etc.
6.
Sets are provided with ventilation openings in the cabinet
to
allow heat generated during operation
to
be released. If these
openings are blocked, heat built up within the set can cause
failures which may result in a fire hazard. Therefore:
• Never
block
the
bottom
ventilation slots by placing
it
on a
bed, sofa, rug, etc.;
• Never place a set
in a "built·in"
enclosure unless proper
ventilation
is
provided;
• Never cover the openings
with
cloth
or
other material;
• Never place the set near
or
over a radiator
or
heat register.
7.
To avoid personal injury:
• Do not place a set on a sloping shelf unless properly
secured;
7
Page 10
• Use only a cart or stand recommended by the manufac-
turer;
•
Do
not try
to
roll a cart with small casters across thresholds
or deep pile carpets.
• Wall and shelf mounted installations should use factory
approved mounting instructions.
USE
8.
Always turn the set off
if
it is necessary
to
leave the room for
more than a short period of time. Never leave a set on when
leaving the house. A possible malfunction may result in a fire
hazard.
9.
Caution children about dropping
or
pushing objects into the
set's cabinet openings. Some internal parts carry hazardous
voltages
and
contact can result
in
a fire or electrical shock.
10.
Unplug the set from the wall outlet before cleaning the face of
the picture tube. Use a slightly damp (not wet) cloth.
Do
not
use
an
aerosol directly
on
the picture tube since it may
overspray and cause electrical shock.
11.
Never add accessories
to
a set that has not been designed for
this purpose. Such additions may result in a shock hazard.
12.
For added protection
of
the set during a lightning storm or
when the set is to be left unattended for
an
extended period of
time, unplug
it
from the wall outlet. This will prevent possible
shock and fire hazards due to lightning storms or power line
surges.
13.
Do
not bring magnetic devices such
as
magnets or motors
near the picture tube. These things
have a bad
effect
on
the
color purity of the picture.
14.
Sometimes you may feel static electricity when you touch the
surface
of
the picture tube. However, this is normal for any
TV
set and is harmless to the human body.

SERVICE
15.
Unplug the set from the wall outlet
and
refer servicing to
qualified service personnel under the following conditions:
A.
When the power cord or plug is damaged or frayed.
B.
If liquid has been spilled into the set.
C.
If the set has been exposed to rain or water.
D.
If the set does not operate normally by following the
operating instructions. Adjust only those controls that are
covered in the operating instructions, as improper adjust-
ment
of
other controls may result in damage and will often
require extensive work by a qualified technician to restore
the set to normal operation.
E.
If the set
has
been dropped or the cabinet
has
been
damaged.
F.
When the set exhibits a distinct change in
performance-
this indicates a need for servicing.
G.
If snapping or popping from the set is continuous or frequent while the set is operating. It is normal for some sets
to make occasional snapping or popping sounds, particu-
larly when being turned on
or
off.
16.
Do not attempt
to
service this set yourself, as opening
or
_
removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing
to
qualified service
personnel.
17.
When replacement parts are required,
have
the service techni-
cian verify
in
writing that the replacements
he
uses
have
the
same safety characteristics
as
the original parts. Use of
manufacturer's specified replacements
can
prevent fire,
shock, or other hazards.
18.
Upon completion of any service or repairs to the set, please
ask the service technician to perform the safety check
described in the manufacturers' service literature.
19.
When a video monitor reaches the end of its useful life,
improper disposal could result in a picture tube implosion.
Ask a qualified service technician to dispose of the set.
Design and specifications subject to change
without
notice.
