							Precaution5 
Precaution
On Safety
 Operate the unit only with a power source as specified 
in the “Specifications” section.
 A nameplate indicating operating voltage, etc., is 
located on the rear panel.
 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.
Handling the LCD Screen
 The LCD panel fitted to this unit is manufactured with 
high precision technology, giving a functioning pixel 
ratio of at least 99.99%. Thus a very small proportion 
of pixels may be “stuck”, either always off (black), 
always on (red, green, or blue), or flashing. In 
addition, over a long period of use, because of the 
physical characteristics of the liquid crystal display, 
such “stuck” pixels may appear spontaneously. These 
problems are not a malfunction.
 Do not leave the LCD screen facing the sun as it can 
damage the LCD screen.  Take care when you place 
the unit by a window.
 Do not push or scratch the LCD monitor’s screen.  Do 
not place a heavy object on the LCD monitor’s screen.  
This may cause the screen to lose uniformity. If the unit is used in a cold place, horizontal lines or a 
residual image may appear on the screen.  This is not 
a malfunction.  When the monitor becomes warm, the 
screen returns to normal.
 If a fixed picture such as a frame of a divided picture 
or time code, or a still picture is displayed for a long 
time, an image may remain on the screen and be 
superimposed as a ghosting image.
 The screen and the cabinet become warm during 
operation.  This is not a malfunction.
About the Fluorescent Tube
A specially designed fluorescent tube is installed as the 
lighting apparatus for this unit.  If the LCD screen 
becomes dark, unstable or does not turn on, consult your 
Sony dealer.
On Cleaning
Before cleaning
Be sure to disconnect the AC power cord from the AC 
outlet.
On cleaning the monitor screen
The monitor screen surface is especially treated to 
reduce reflection of light.
As incorrect maintenance may impair the performance 
of the monitor, take care with respect to the following:
 Wipe the screen gently with a soft cloth such as a 
cleaning cloth or glass cleaning cloth.
 Stubborn stains may be removed with a soft cloth such 
as a cleaning cloth or glass cleaning cloth lightly 
dampened with water.
 Never use solvent such as alcohol, benzene or thinner, 
or acid, alkaline or abrasive detergent, or chemical 
cleaning cloth, as they will damage the screen surface.
On cleaning the cabinet
 Clean the cabinet gently with a soft dry cloth. 
Stubborn stains may be removed with a cloth lightly 
dampened with mild detergent solution, followed by 
wiping with a soft dry cloth.
 Use of alcohol, benzene, thinner or insecticide may 
damage the finish of the cabinet or remove the 
indications on the cabinet. Do not use these chemicals.
 If you rub on the cabinet with a stained cloth, the 
cabinet may be scratched.
 If the cabinet is in contact with a rubber or vinyl resin 
product for a long period of time, the finish of the 
cabinet may deteriorate or the coating may come off.

On Repacking
Do not throw away the carton and packing materials. 
They make an ideal container which to transport the 
unit. 
On Mounting on a Rack
Leave 1U space empty above and below the monitor to 
ensure adequate air circulation or install a fan to 
maintain the monitor’s performance.
If you have any questions about this unit, contact your 
authorized Sony dealer.
On Fan Error (LMD-2450W)
The fan for cooling the unit is built in. When the fan 
stops and the RETURN button on the front panel blinks 
for fan error indication, turn off the power and contact an 
authorized Sony dealer.
Features
The LMD-2450W (24-inch)/LMD-2050W (20-inch) is 
a multiple format LCD monitor for broadcast or 
business use featuring a precise image and high 
performance. It supports both digital or analog main 
broadcast signal and PC input.  It is also equipped with 
functions to adjust for various objects or use. 
High brightness LCD panel
Because of precise image, wide viewing angle 
technology and high speed response, real color image 
can be reproduced. 
Multi-format
The monitor supports the video, Y/C, RGB, component, 
SDI (HD/D1, when the optional input adaptor is used.) 
signals and NTSC/PAL color systems.  HD15 (analog) 
and DVI-D (digital) connectors are equipped for the PC 
input.
For more information, refer to “Available signal 
formats” on page 34.

two adaptors can be installed.
For more information, refer to “Available signal 
formats” on page 34.
External remote function
The input signal is selected or various items are adjusted 
by use of the serial (Ethernet) remote function.  Up to 32 
monitors and control units (max. 4) can be connected by 
the Ethernet (10BASE-T/100BASE-TX) connection 
and controlled remotely on the network.  You can 
control individual monitors or monitor groups simply by 
entering the monitor ID or group ID number.  You can 
also execute the same operation on all connected 
monitors, or put all connected monitors into the same 
setup and adjustment state.
For more information, refer to SERIAL REMOTE of 
“REMOTE menu” on page 30.
Refer to the Operation Manual of the BKM-15R Monitor 
Control Unit.
