SAFETY PRECAUTIONS
In order to prevent any fatal accidents caused by misoperation
or mishandling the monitor, be fully aware of all the following
precautions.
WARNINGS
To prevent fire or shock hazard, do not expose this
monitor to rain or moisture. Dangerous high voltages
are present inside the unit. Do not remove the back
cover of the cabinet.When servicing the monitor,
contact qualified service personnel. Never try to service
it yourself.
PRECAUTIONS
●Use only the power source specified on the unit.
●When not using this unit for a long period of time, or when
cleaning it, be sure to disconnect the power plug from the
AC outlet.
●Do not allow anything to rest on the power cord. And do not
place this unit where people will tread on the cord.
●Do not overload wall outlets or power cords as this can
result in a fire or electric shock.
●Avoid using this unit under the following conditions:
– in extremely hot, cold or humid places,
– in dusty places,
– near appliances generating strong magnetic fields,
– in places subject to direct sunlight,
– in badly ventilated places,
– in automobiles with doors closed
●Do not cover the ventilation slots while in operation as this
could obstruct the required ventilation flow.
●When dust accumulates on the screen surface, clean it with
a soft cloth.
●Unplug this unit from the AC outlet and refer servicing to
qualified service personnel under the following conditions:
– when the power cord is frayed or the plug is damaged,
– if liquid has been spilled into the unit,
– if the unit has been dropped or the cabinet has been
damaged,
– when the unit exhibits a distinct change in performance.
●Do not attempt to service this unit yourself as opening or
removing covers may expose you to dangerous voltage or
other hazards.Always refer servicing to qualified service
personnel.
●When replacement parts are required, have the service
personnel verify in writing that the replacement parts he/she
uses have the same safety characteristics as the original
parts. Use of manufacture's specified replacement parts can
prevent fire, shock, or other hazards.
●Upon completion of any servicing or repair work to this unit,
please ask the service personnel to perform the safety check
described in the manufacturer's service literature.
●When this unit reaches the end of its useful life, improper
disposal could result in a picture tube implosion. Ask
qualified service personnel to dispose of this unit.
SCREEN BURN
●It is not recommended to keep a certain still image displayed on screen for a long time as well as displaying extremely bright
images on screen.This may cause a burning (sticking) phenomenon on the screen of cathode-ray tube.This problem does not
occur as far as displaying normal video playback motion images.
Thank you for purchasing this JVC colour video monitor. Before using it, read and follow
all instructions carefully to take full advantage of the monitor's capabilities.
WARNING : THIS APPARATUS
MUST BE EARTHED.
Machine Noise Information Ordinance 3. GSGV, January
18, 1991: The sound pressure level at the operator
position is equal or less than 70 dB (A) according to ISO
7779.
Improper operations, in particular alternation of high
voltage or changing the type of tube may result in x-ray
emission of considerable dose.A unit altered in such a
way no longer meets the standards of certification, and
must therefore no longer be operated.

POWER CONNECTION
WARNING
Do not cut off the main plug from this equipment.
If the plug fitted is not suitable for the power points in your
home or the cable is too short to reach a power point, then
obtain an appropriate safety approved extension lead or
adapter or consult your dealer.
If nonetheless the mains plug is cut off, remove the fuse and
dispose of the plug immediately, to avoid a possible shock
hazard by inadvertent connection to the main supply.
If a new main plug has to be fitted, then follow the instruction
given below:
WARNING:
THIS APPARATUS MUST BE EARTHED.
IMPORTANT.
The wires in the mains lead on this product are coloured in
accordance with the following cord:
Green-and-yellow : Earth
Blue : Neutral
Brown : Live
As these colours may not correspond with the coloured
making identifying the terminals in your plug, proceed as
follows:
Thewire which is coloured green-and-yellowmust be connected
to the terminal which is marked with the letter E or the safety
earth symbol Gor coloured green or green-and-yellow.
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal which is marked with the letter L or coloured red.
When replacing the fuse, be sure to use only a correctly rated
approved type, re-fit the fuse cover.
IF IN DOUBT —— CONSULT A COMPETENT ELECTRI-
CIAN.

BASIC CONNECTION EXAMPLE
Notes:
●Before connecting your system, make sure that all units are turned off.
●The illustration below shows some examples of different connections.Terminal connections may differ depending on the
component connected. Be sure to refer to the instructions provided with the unit(s) you are connecting.
●Each pair of input (IN) and output (OUT) terminals are bridge-connected. However, theY/C input terminal (Y/C IN) has no output
terminal (OUT) corresponding to it.
●If you’re not connecting any equipment to a bridged output (OUT) terminal, be sure not to connect any other cables to the
bridged output (OUT) terminal as this will cause the terminating resistance switch to open (auto terminate function).
●When making a bridge connection, connect the input (IN) and output (OUT) terminals on the monitor to separate video
components.
(For example, if both terminals are connected to the same VCR, resonance may occur except during playback.This is caused
by the same video signal “looping”between the VCRs, and is not a malfunction.)
●Select the video input (Input A or Input B) with the input select button on the front panel.

Measures (Remedy)
Firmly insert the power plug.
Set the connected component correctly.
Select the required video signal input with the
Input select button. (See page 6.)
Connect the video signal cable firmly.
(See page 11.)
Set the connected component correctly.

(See page 11.)
Move the device away from the monitor until the
picture stabilizes.
Set the COLOR SYSTEM in the <MENU> screen
mode to [AUTO] mode. (See page 7.)
Set each picture control to the standard setting.
(See page 6.)
Move the device away from the monitor and turn
the monitor’s power off.Wait at least 30 minutes,
then turn the power on again.
Set the CONTROL LOCK to OFF in the <SET-
UP MENU> screen mode. (See pages 8 and 9.)
TROUBLESHOOTING
Solutions to common problems related to your monitor are described here. If none of the solutions presented here
solves the problem, unplug the monitor and consult a JVC-authorized dealer or service center for assistance.
The following are not malfunctions:
●When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be coloured.This is due to the
structure of the cathode ray tube and will be deleted when another image is displayed.
●You experience a mild electric shock when you touch the picture tube.This phenomenon is due to a normal buildup of static
electricity on the CRT and is not harmful.
●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.
