About this manual
Before operating the unit, please read this manual
thoroughly and retain it for future reference.
The explanation given in this manual can be applied to
the following models unless noted otherwise.
When explanation differs among models, this is clearly
indicated in this manual.
• PVM-14N5A/14N5E/14N5U (14-inch monitor)
• PVM-14N6A/14N6E/14N6U (14-inch monitor)
• PVM-20N5A/20N5E/20N5U (20-inch monitor)
• PVM-20N6A/20N6E/20N6U (20-inch monitor)
Illustrations of the video monitor are for the PVM-
20N6A/20N6E/20N6U.
On safety
• Operate the unit only with a power source as
specified in “Specifications” section.
• The nameplate indicating operating voltage, power
consumption, etc., is located at the rear.
• 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.
• Do not drop or place heavy objects on the power
cord. If the power cord is damaged, turn off the
power immediately. It is dangerous to use the unit
with a damaged power cord.
• Unplug the unit from the wall outlet if it is not to be
used for several days or more.
• Disconnect the power cord from the AC outlet by
grasping the plug, not by pulling the cord.
• The socket-outlet shall be installed near the
equipment and shall be easily accessible.
On installation
• 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 cleaning
To keep the unit looking brand-new, periodically clean
it with a mild detergent solution. Never use strong
solvents such as thinner or benzine, or abrasive
cleansers since they 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 which to transport the
unit.
If you have any questions about this unit, contact your
authorized Sony dealer.

On-screen menus
You can set monitor operation settings by using the
on-screen menus.
EIA standard 19-inch rack mounting
By using an MB-502B mounting bracket (for a 14-inch
monitor, not supplied) or SLR-103A slide rail (for a
20-inch monitor, not supplied), the monitor can be
mounted in an EIA standard 19-inch rack.
Attention – when the product is installed in a rack:
• Elevated operating ambient temperature
If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of
the rack environment may be greater than room
ambient.
Therefore, consideration should be given to
installing the equipment in an environment
compatible with the manufacturer’s maximum
rated ambient temperature of 0 to +35 ºC (Tmra).
• Reduced air flow
Installation of the equipment in a rack should be
such that the amount of air flow required for safe
operation of the equipment is not compromised.
• Mechanical loading
Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved
due to uneven mechanical loading.
• Circuit overloading
Consideration should be given to the connection
of the equipment to the supply circuit and the
effect that overloading of circuits might have on
overcurrent protection and supply wiring.
Appropriate consideration of equipment
nameplate ratings should be used when
addressing this concern.
• Reliable earthing
Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should
be given to supply connections other than direct
connections to the branch circuit (e.g., use of
power strips).
Fine pitch Trinitron1) picture tube
The fine pitch Trinitron tube provides a high resolution
picture. Horizontal resolution is more than 500 TV
lines at the center of the picture.
Comb filter
When NTSC video signals are received, a comb filter
activates to make more accurate Y/C separation. This
contributes to less of a decrease in resolution, cross
color and cross luminance phenomena.
Beam current feedback circuit
The built-in beam current feedback circuit assures
stable white balance.

Analog RGB signals from video equipment can be
input through these connectors.
Y/C input connectors
The video signal, split into the chrominance 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, ensuring video quality.

1) Trinitron
“Trinitron” is a registered trademark of Sony Corporation.
2) NTSC4.43
The NTSC4.43 system refers to an NTSC color system in which the subcarrier frequency is modified to 4.43MHz. When an
NTSC recorded video program is played back with a Trident (PAL/SECAM/NTSC4.43) VTR, the NTSC4.43 signal is output.
