instructions in the literature accompa•
nying the appliance.
For the customers in the USA
Warning - This equipment generates, uses. and can radiate
radio frequency energy and If not installed and used In
accordance with the instructions manual, may cause
interference to radio communications. It has been tested and

that the individual equipment of the complete system has a
label with one of the following statements.
"This equipment has been tested with a Class A
Computing Device and has been found to comply with
Part 15of FCC Rules."
-or-
"This equipment complies with the requirements in Part
15 of FCC Rules for a Class A Computing Device."
-or equivalent.
Be sure to connect the AC power cord to a grounded
outlet.

Precautions
On safety
• Operate the unit only on 120 V AC.
• Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
• Unplug the unit from the wall outlet if It is not to be used for
several days or more.
• To disconnect the AC power cord, pull it out by grasping
the plug. Never pull the cord itself.
On lnstaHatlon
• Allow adequate air circulation to prevent internal heat
build-up.
Do not place the unit on surfaces (rugs, blankets, etc.) or
near materials (curtains, draperies) that may block the
ventilation holes.
• Do not install the unit in a location near heat sources such
as radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or shock.
On deaning
To keep the unit looking brand•new, periodically clean it with
a soft cloth. Stubborn stains may be removed with a cloth
lightly dampened with a mild detergent solution. Never use
strong solvents such as thinner or benzine, or abrasive
cleansers since these will damage the cabinet. As a safety
precaution, unplug the unit before cleaning it.
On repacking
Do not throw away the carton and packing materials. They
make an ideal container In which to transport the unit. When
shipping the unit to another location, repack it as illustrated
on the carton.
If you have any questions about this unit, contact your
authorized Sonv dealer.

Automatic beam cu1Tent feedback circuit
The automatic beam current feedback circuit compensates
for the beam distortion, secular distortion of the cathode-ray
tube, etc., and always reproduces the same white display on
the screen. This allows an extended use of the monitor.
Super Fine Pitch Trinltron picture tube
The Super Fine Pitch Trlnltron picture tube (0.4 mm aperture
grill) gives high resolution picture. Horizontal resolution Is
more than 6001V lines at the center of the picture. When
used as a character display, up to 2,000 characters (80
characters/line x 25 lines) can be displayed with great clarity.
Analog RGB/component connector (PVM-19440 only)
Analog RGB and component signals of a video equipment
can be Input through this connector. The signals are
selected by the COMPO/RGB selector on the rear panel.
Analog RGB connector (PVM-19420 only)
Analog RGB signal of a video equipment can be input
through this connector.
Digital RGB input connector (PVM-19420 only)
Digital RGB signal from a microcomputer can be Input
through this connector.
VIC input connector
The video signal split Into the chromlnance signal (C) and the
luminance signal (Y) can be Input through this connector,
eliminating the Interference between the two signals which
tends to occur In a composite video signal and assuring the
video quality.
VTR input connector
When connected to a VTR having the 8-pin 1V connector,
video and audio signals can be fed through this connector
with a single cable.
Control S connector
When this connector Is connected to the "control S" output
of other equipment, the remote controls of the aperture,
brightness, chroma, phase, contrast and volume settings are
possible.
Automatic release of BNC-type connector termination
The BNCtype Input connector Is terminated at 75 ohms
Inside when the BNCtype output connector Is open. When a
cable Is connected to the BNCtype output connector, the
75-ohm termination Is automatically released, and the signal
Input through the IN connector Is output from the
corresponding OUT connector.
Four color systems available
The monitor can display PAL, SECAM, NTSC3.5B and
NTSC.1.43• signals. The appropriate color system is selected
automatically.
• A signal of NTSC4.43 is obtained by playing back NTSC·
recorded video cassettes with a video tape recorder/player
espec\a\\~ des\gned tor use w\th th\s system.
3.58 (MHz) TRAP button (NTSCasa only)
This button can be used to eliminate the dot interference to
the luminance signal appearing between colors In the
horizontal direction, which Is one of the characteristics of the
comb filter.
Comb filter
When NTSC video signals are received, a comb filter
activates to increase the resolution, resulting in fine picture
detail without color spill or color noise.
Blue only mode
In the blue only mode, an apparent monochrome display is
obtained with all three cathodes driven with a blue signal.
This facilitates color saturation and phase adjustments and
observation of VTR noise.
Underscan mode
The signal normally scanned outside of the screen can be
monitored In the underscan mode.
-
The bright scanning lines which may appear on the top edge
of the screen when the monitor is In the underscan mode are
caused by an internal test signal, rather than the input signal.
Horizontal/vertical delay mode
The horizontal and vertical sync signals can be checked
simultaneously in the HN delay mode.
User's control merno,y (PVM-19440 only)
The desired aperture, brightness, chroma, and phase levels
can be memorized.
External sync input
When the EXT SYNC (or ANALOG/DIGIT AL (EXT SYNC))
button is depressed, the monitor can be operated on the
sync signal supplied from an external sync generator.
Color temperature selector
Color temperature of either 9,300°K or 6,500°K is selectable
with the COLOR TEMP selector. For precise adjustment, use
the BIAS and GAIN adjustment controls.
Light-touch picture adjustment buttons
The aperture, brightness, chroma, phase, contrast and
volume buttons can be adjusted by touching the buttons
lightly. The adjusted settings will be stored In memory even
when the monitor is turned off.
Auto/manual degaussing
Degaussing of the screen can be performed automatically
when the power is turned on, or manually by pressing the
DEGAUSS button.
EIA standard 19-inch rack mounting
By using an optional SLR101 slide rail, the monitor can be
mounted in an EIA standard 19-inch rack. For details on
mounting, see the appropriate Instruction manual.
