Chapter 1 Overview
Precautions
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. 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 Sony dealer.
On rack mounting
When the monitor is mounted on a rack, the
temperature around the monitor may rise due to heat
generated from other equipment and reduced air
circulation, causing damage to the monitor. To
prevent this, keep ventilation holes, install a ventilation
fan or take other effective countermeasures so that the
temperature around the monitor is within the specified
range: operating temperature of 0 to 35 °C (32 to
95°F), optimum temperature of 20 to 30°C (68 to
86°F).
On magnetism
• Do not place the unit near any objects or pieces of
equipment which generate magnetism, such as
magnets, speakers, electric clocks, toys using
magnets, health appliances, etc. Magnetism will
cause picture bounce, oscillations or picture
discoloration.
• Also, the picture may become fuzzy or the colors
may not reproduce correctly due to earth magnetism.
This depends on direction that the unit is installed.
This is not equipment failure. In such a case, simply
degauss the unit.
On the CRT
• Dust accumulates on the CRT easily. Clean the CRT
when necessary with a soft cloth.
The surface of the CRT is easily scratched; therefore,
do not rub or touch the surface of the CRT
unnecessarily since this may result in a scratched
picture tube.
• If you touch the surface of the CRT, you may feel a
weak electrical shock. This is simply static electricity
that is generated on the surface of the CRT. It will not
affect the human body.
On displaying the 4:3 signal (BVM-
D20F1U/D20F1E/D20F1A only)
The 16:9 mask has been attached to the BVM-
D20F1U/D20F1E/D20F1A at the factory. If the 16:9
button is pressed to change to the 4:3 aspect mode in
this condition, the upper and lower portions of the
image is hidden by the mask. To display the 4:3
image, replace the 16:9 mask with the supplied 4:3
mask.
For details, see “Installation of the 4:3 Mask” on page 21.
