IMPORTANT SAFEGUARDS
CAUTION:
Please read and retain for your safety.
Electrical energy can perform many useful
functions. This Appliance 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
Appliance, observe the following basic rules for
its installation, use and servicing.
And also follow all warnings and instructions
marked on your Appliance.
INSTALLATION
1 Your Appliance is equipped with a
grounding-type AC line plug (three-blade
type), a plug having a third (grounding)
pin.
(GROUNDING-TYPE)
This plug will only fit into a grounding-type
power outlet. This is a safety feature.
Should you be unable to insert the plug
into the outlet, contact your electrician to
replace your outlet. Do not defeat the
safety purpose of the grounding-type plug.
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 on or roll
over the power cord, and do not place the
Appliance where power cord is subject to
traffic or abuse. This may result in a shock
or fire hazard.
5 Do not use this Appliance near water —
for example, near a bathtub, washbowl,
kitchen sink, or laundry tub, in a wet
basement, or near swimming pool, etc.
6 If an outside antenna is connected to the
Appliance, be sure the antenna system is
grounded so as to provide some protection
against voltage surges and built-up static
charges. Section 810 of the National
Electrical Code provides information with
respect to proper grounding of the mast
and supporting structure, grounding of the
lead-in wire to an antenna discharge unit,
size of grounding conductors, location of
antenna discharge unit, connection
requirements for the grounding electrode.
2 Operate the Appliance only from a power
source as indicated on the Appliance or
refer to the operating instructions for this
information. If you are not sure of the type
of power supply to your home, consult
your Appliance dealer or local power
company. For battery operation, refer to
the operating instructions.
(continued on the next page)

7 An outside antenna system should not be
located in the vicinity of overhead power
lines or other electric light or power
circuits, or where it can fall into such
power lines or circuits. When installing an
outside antenna system, extreme care
should be taken to keep from touching
such power lines or circuits as contact
with them might be fatal.
EXAMPLE OF ANTENNA GROUNDING
AS PER NATIONAL ELECTRICAL CODE
9 To avoid personal injury:
– Do not place an Appliance on a sloping
shelf unless properly secured.

10 Caution children about dropping or
pushing objects into the Appliance through
cabinet openings. Some internal parts
carry hazardous voltages and contact can
result in a fire or electrical shock.
11 Unplug the Appliance from the wall outlet
before cleaning. Do not use liquid or an
aerosol cleaner.
12 Never add accessories to an Appliance
that has not been designed for this
purpose. Such additions may result in a
hazard.
13 For added protection of the Appliance
during a lightning storm or when the
Appliance is to be left unattended for an
extended period of time, unplug it from the
wall outlet and disconnect the antenna.
This will prevent damage to product due
to lightning storms or power line surges.
14 An Appliance and cart combination should
be moved with care. Quick stops, excessive
force, and uneven surfaces may cause the
Appliance and cart combination to overturn.
16 Do not attempt to service this Appliance
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 technician verify in
writing that the replacement parts he uses
have the same safety characteristics as
the original parts. Use of manufacturer’s
specified replacement parts can prevent
fire, shock, or other hazards.

15 Unplug this Appliance 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
Appliance.
C.If the Appliance has been exposed to
rain or water.
D.If the Appliance does not operate
normally by following the operating
instructions. Adjust only those controls
that are covered in the operating
instructions as improper adjustment of
other controls may result in damage
and will often require extensive work by
a qualified technician to restore the
Appliance to normal operation.
E. If the Appliance has been dropped or
damaged in any way.
F. When the Appliance exhibits a distinct
change in performance — this indicates
a need for service.
18 Upon completion of any service or repairs
to this Appliance, please ask the service
technician to perform the safety check
described in the manufacturer’s service
literature.
19 When an Appliance 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
Appliance.
20 Note to CATV system installer.
This reminder is provided to call the CATV
system installer’s attention to Article 82040 of the NEC that provides guidelines for
proper grounding and, in particular,
specifies that the cable ground shall be
connected to the grounding system of the
building, as close to the point of cable
entry as practical.
SCREEN BURN
● Try to avoid displaying still images or extremely bright images on the screen for an extended
period of time. If left on screen for too long the image will be permanently etched onto the
CRT — a phenomenon known as “screen burn”. Screen burn is not a problem when
displaying moving pictures during video playback.

SETTING TV CHANNELS
This monitor is factory-preset to tune all VHF (2 to
13) and UHF (14 to 69) TV channels.
● To perform the following, press the TV button to
select TV.
When you want to reset the memorized TV
channels, perform CH SEARCH START (initiate
channel search) from the menu screen (refer to
pages 14 and 15). The monitor automatically
searches for broadcasting stations (VHF/UHF) and
memorizes them.
You can also delete channels you do not want to
watch. Select the channel to be deleted and
perform CH SKIP ON (channel skip ON) from the
menu screen (refer to pages 14 and 15).
* Channels deleted by CH SKIP ON (channel skip
ON) cannot be tuned again. If you want to tune
them, perform CH RESET ON (channel reset ON)
from the menu screen to tune all VHF (2 to 13)
and UHF (14 to 69) TV channels.
* In areas where the radio wave reception weak,
searching for TV channels will not function well.
In this case, perform CH RESET ON (channel
reset ON) from the menu screen to tune all VHF
(2 to 13) and UHF (14 to 69) TV channels.

value [0].
Some parts of the
picture are
distorted.
Is the monitor close to a speaker or
magnet? Did you move a speaker or
magnet close to the monitor?
Keep speakers and magnets away
from the monitor.
There are black
parts on the top
and bottom of the
screen, and both
horizontal sides of
the picture is
indented.
Is the screen size set to 16:9?
Set the screen size to OVER or
UNDER.
(continued on the next page)
18
Problems
Points to be checked
Measures (remedy)
The screen size is
small.
Is the screen size set to UNDER?
Set the screen size to OVER.
There is no TV
reception.
Is an antenna connected to the
monitor?
Connect the TV antenna cable.
Was the monitor moved to an area that
receives different channels after CH
SEARCH START (initiate channel
search) was performed?
Perform CH SEARCH START each
time the monitor is moved to an area
that receives different channels so
that the monitor can memorize the
new broadcast stations. Otherwise,
perform CH RESET ON (channel
reset ON) to tune all TV channels.
There may not be a solution to the following problems, although adjusting the antenna or taking
measures against interfering equipment may improve the situation somewhat.
The screen appears snowy and noise is heard. (Snow)
● Is the antenna connected properly?
● Has the antenna cable been cut or loosened?
● Has the antenna orientation been changed or is the antenna broken?
The image is displayed two or three times on the monitor. (Ghosting)
● This may be caused by mountains or buildings. Also, if the broadcast antenna is located nearby,
the TV transmission the monitor receives directly from it may affect the picture.
Spots are displayed and noise is heard. (Interference)
● This may be caused by interfering radio waves generated by dryers, automobiles, motorcycles or
fluorescent lights.
Stripes are displayed and noise is heard. (Radio Interference)
● This may be caused by radio interference generated by radio stations, personal computers, AV
equipment or microwave ovens.
The following are not malfunctions:
● The monitor emits a strange sound when the room temperature changes suddenly. This is only a
problem if an abnormality appears on the screen as well.
● If two or more monitors are operated next to each other, their images may shake or be distorted. This
phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each
other until the interference disappears or turn the power off on any monitor that is not being used.
● If a magnet or speaker is placed close to the monitor, the picture may shake. This is caused by the
magnetic effect and is not a malfunction.
● When the monitor is turned ON, the sound of a running motor may be heard. This is the cooling fan and
is not a malfunction.
● When playing back a video tape, the upper edge of the picture may be distorted. This is caused by
skew distortion and is not a malfunction.
● Vertical stripes may occur on a dark picture. This is caused by quantization noise (noise which occurs
when a picture is digitized) and is not a malfunction.

CHARACTERISTICS OF LCCS
VIDEO MONITOR SYSTEM
■ PRINCIPLE BEHIND LCCS VIDEO MONITOR OPERATION
The LCCS Video Monitor is a combination of a black-and-white cathode-ray tube and liquid crystal color
shutter (LCCS), which are used together to reproduce color images.
The video signal input to the monitor is demodulated into RGB primary color signals which are then
stored in the field memory. Signals in the field memory are read three times faster than the input video
signal is, and are displayed on the black-and-white cathode-ray tube in the order of R, G and B. (Three
images are displayed during one field.)
Color filters on the liquid crystal color shutter change according to the displayed primary color signal,
transforming the black-and-white images into R, G and B primary color images.
Because of the phenomenon known as persistence of vision, the R, G and B primary color images appear
as a single color image to the human eye.
䡲 FEATURES OF LCCS VIDEO MONITOR
• High Contrast
Thanks to its low permeability, the liquid crystal color shutter (LCCS) does not reflect outside light as
much, enabling it to reproduce high-contrast images even in direct sunlight.
• High Resolution
The use of a black-and-white cathode-ray tube (which has no picture elements) and a liquid crystal color
shutter (LCCS) allows it to display images at high resolution.
• No Irregular Color Caused By Magnetic Interference
Unlike with color cathode-ray tubes, irregular color does not occur on the display because the monitor
does not have any color elements.
• No Moire Patterns
Horizontal moire patterns (interference fringes) do not occur because the monitor does not have any
color elements.
䡲 THE FOLLOWING ARE NOT MALFUNCTIONS:
● Picture hue changes depending on the angle from which the monitor is viewed.
This is due to normal characteristics of the liquid crystal color shutter.
● Two horizontal stripes are displayed on the picture.
This is due to the structure of the liquid crystal color shutter.
● Simple color image is displayed for an instant.
This is due to normal characteristics of the LCCS video monitor.
● Patterns such as spots are displayed when the monitor is turned ON or OFF.
This is due to normal characteristics of the liquid crystal color shutter.
● The color of characters or images seem to be shifted.
This is due to normal characteristic of the LCCS video monitor.
When images combined with a Macrovision copy protection signal or jittery images from a VCR, etc.
are displayed on the monitor, their color may appear to be shifted.

Notes about Magnets
● DO NOT place the following close to the
monitor: magnets, speakers, electric clocks,
devices or toys which use a magnet, medical
devices which use a magnet, or any other
products which generate a magnetic field.
Doing so may cause the picture to be
distorted by their magnetic effect. Also, DO
NOT place the monitor close to a high-voltage
power line or transformer.
● If an external speaker is placed close to the
monitor, the picture may be distorted. In this
case, use a shielded speaker.
