Sony TRINITRON BVM-14G1A Operation And Maintenance Manual page 12

Precaution
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 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.

Separate control unit (BVM-20G1U/20G1E/
20G1A/14G1U/14G1E/14G1A only)
The BVM-20G1U/20G1E/20G1A/14G1U/14G1E/
14G1A are controlled by a separate control unit, such
as an optional BKM-10R/11R Monitor Control unit.
Using a separate control unit reduces the space needed
for the equipment. The BVM-20G1U/20G1E/20G1A
can be connected to the BKM-10R via an optional
BKM-32H Monitor Control Unit Attachment Kit.
Controlling monitor groups
Up to 32 monitors can be controlled from this monitor.
First, using the monitor menus, assign a monitor
address number to each monitor, divide the monitors
into groups, and assign a group number to each group.
Then you can use this monitor to control individual
monitors or monitor groups simply by entering
monitor address or group numbers. You can also
execute the same operation on all connected monitors,
or use this monitor to put all connected monitors into
the same setup and adjustment state.

Setup and adjustment with the Monitor
Memory Card
You can use an optional BKM-12Y Monitor Memory
Card to save and load monitor setup and adjustment
data. If your system includes more than one monitor,
you can use the monitor memory cards to exchange
data between monitors. This makes it easy to put all
monitors in your system into the same setup and
adjustment state.
Standard auto alignment system
Decoder chroma and phase adjustment, as well as
color temperature control, may be performed with the
auto alignment system. This makes it possible to
coordinate settings among multiple monitors.
Expandable input capability
The input connector configuration may be easily
modified by simply sliding optional decoder adaptor or
the input expansion adaptor into input option slot at the
rear of the monitor.
4:3/16:9 dual aspect ratio design
This monitor can be changed to either 4:3 or 16:9
aspect ratio with just a simple switching operation. The
screen can be also changed to 4:3 or 16:9 display by
the replacement of a mask (no tools required).
Stable color temperature
The internal beam current feedback circuit maintains a
constant color temperature over long periods of time.
Blue-only mode convenient for monitoring
noise
All three CRT cathodes can be driven with a blue
signal, producing a monochrome display. This mode
is convenient for chroma and phase adjustment, and
for monitoring VTR noise.
Menu operation
The monitor's various functions and operating
conditions can be set with on-screen menus.
