About the STATUS indication
● With the COLOR SYSTEM setting set
to AUTO mode, when you turn on the
power or select inputs, the color
system indication appears for about
3 seconds on the screen while PAL or
NTSC signals are being detected.
    It does not appear when receiving a
B/W signal or when no signal is input.
   Refer to page 11 for more information
about COLOR SYSTEM setting and
page 13 for more information about
STATUS indication setting.
Notes:
● Phase control is effective only in the
NTSC color system mode.
● Chroma control is not effective when
receiving RGB and B/W or when no
signal is input. (Except when a
component signal is input.)
● When CHROMA is adjusted to “–40,”
the picture becomes less colorful.
● “NO EFFECT” is displayed (for about
3 seconds) when your selected
function has no effect.
● To change the display position on
screen, set UPPER or LOWER with
ADJ. BAR POSI.

VIDEO SIGNAL CONTROLS
Use these buttons for video signal control.
UNDER SCAN
Press the UNDER SCAN button to reduce the size of display area so that the whole
picture is displayed on screen.  Use to check the picture frame.
COLOR OFF
To display a black and white picture, press the COLOR OFF button to input the luminance
signal only.  Use to check noise in the luminance signal or for white balance adjustment.
Note:
●No effect with RGB input.
BLUE CHECK
Input the standard color-bar signal for your TV system and display it on the screen.
When the BLUE CHECK button is pressed, the red and green signals are cut and only
the blue signal is displayed. The BLUE CHECK function adjusts and checks CHROMA
(COLOR) GAIN and PHASE.
Make sure that COMPO. LEVEL has been initialized when a component signal is input.
[Procedure]
1. Input the standard color-bar signal for your TV system and display it on the screen.
2. Press the BLUE CHECK button.
3. Press the CHROMA button to adjust the chroma so that the blue bars on the left and
right sides of the screen have the same brightness.
4. (Only when an NTSC signal is input) Press the PHASE button to adjust the phase so
that the two blue bars at the center of the screen have the same brightness.
5. (Only when an NTSC signal is input) Repeat procedures 3 and 4 for the adjustment so
that all four blue bars on the screen have the same brightness.
When you have finished making the adjustment, press the BLUE CHECK button to
deactivate.
Initializing COMPO. LEVEL (when a component signal is input)
with the IF-C01COMG component/RGB input card inserted
When a component signal is input, be sure to adjust (initialize) the COLOR offset in
COMPO. LEVEL.
[Procedure]
1. Input the standard color-bar signal for your TV system and display it on the screen.
2. Press the BLUE CHECK button.
3. Select COMPO. LEVEL in the  screen and then adjust it with VOLUME +/–
buttons so that the blue bars on the left and right sides of the screen have the same
brightness.
4. Quit the  screen and press the BLUE CHECK button.
5. Make sure that the blue bars on the left and right sides of the screen have the same
brightness.

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.• 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 signal (INPUT A(VIDEO) or INPUT B (VIDEO/Y/C)) with the INPUT SELECT buttons on the front panel.  When both
VIDEO B terminals are connected (input) at the same time, the Y/C terminal has priority.

HOW TO USE EXTERNAL
CONTROL
ABOUT EXTERNAL CONTROL
This monitor is provided with an external control terminal.  MAKE (make contact) or TRIG. (trigger) system can be selected by
the setting of REMOTE SYSTEM  in the .
MAKE (make contact system) : The functino is controlled by short-circuiting or disconnecting each control terminal with pin 15
(GND).
TRG. (trigger system) : The function is controlled by short-circuiting with pulses (for about 1 second) (short-circuit/open
with the 15th pin GND).
* The 14th pin (REMOTE ENABLE) is controlled with MAKE even though TRG. is selected.
* The 1st pin (TALLY) is always controlled by the make contact system regardless of the setting (ON/OFF) of the 14th pin
(REMOTE ENABLE) or  the REMOTE SYSTEM setting (MAKE, TRG.) in .
Note:
●When this monitor is externally controlled, the following buttons are disabled.
MAKE: INPUT-A to D, UNDER SCAN, COLOR OFF, ASPECT on the front panel.
*1 : OFF stands for disconnection, and ON stands for short-circuit.
*2 : When INPUT REMOTE in the  is set to A/B, OFF means “select INPUT A” and ON means “select INPUT B”.
*3 : When INPUT REMOTE in the set-up menu is set to A/B, pins not used should not be connected.
*4 : Do not connect.
*5 : Setting REMOTE ENABLE to ON enables external control from each terminal. (Only TALLY can be externally controlled all the time.)
*6 : INPUT REMOTE setting in the set-up menu (REMOTE SYSTEM shown only when MAKE is selected.)
For the D-sub pins 2, 3, 4 and 5, 4-pin or 1-pin control can be set with INPUT REMOTE in the set-up menu.
• 4-pin control: Switches input by short-circuiting a specified signal line in INPUT A to D.
• 1-pin control: Switches between INPUT-A and INPUT-B only with the 2nd pin of the D-sub connector.  In this case, INPUT-C and INPUT-D
cannot be selected.
OFF : INPUT A
ON : INPUT B
NOTES :
* When more than two terminals are selected (short-circuited) from INPUT A through INPUT D under the MAKE system, the signal
input is prioritized alphabetically (A, B, C, D).
* To control INPUT A through INPUT D under the MAKE system, we recommend using the interlock switch, which turns off a
switch when another switch is turned on.
To control INPUT A through INPUT D under the TRG. system, we recommend using the return switch, which stays ON while
pressed.

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 colored. 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.
