Wireless Projection the Easy Way
The PT-LB51NTU’s wireless ability completely
eliminates the need for PC cable connection.
You simply bring in your laptop (with a wire-
less LAN function) for smooth, hassle-free pre-
sentations and flexible room layouts. The sup-
plied Wireless Manager ME 4.5 software
makes setup quick and easy, and a host of
wireless functions complement projector appli-
cations. On top of all this, the 
PT-LB51NTU, PT-LB51U and PT-LB51SU incor-
porate Panasonic’s original Daylight 
View 2 technology, which makes images easy
to see even in brightly lit rooms.Easy Wireless Projection
(PT-LB51NTU)
Easy Wireless Projection from Multiple PCs
You can make the settings for wireless connection
quickly and easily using Wireless Manager ME 4.5
software. When the presentation is finished,
Wireless Manager restores the PC to its previous
LAN settings, so the PC is ready to reconnect to
your LAN. Wireless Manager functions include Live
mode and Multi-Live mode. In Live mode, the
image projected is identical to the image seen on
the PC screen. In Multi-Live mode, you can wire-
lessly connect with multiple PCs.Virtual Remote Control
The same graphics used on the
projector’s remote control can be
displayed on the PC screen. This
makes it easy to operate the pro-
jector right from the PC, without
having to use the remote control.
Easy Connection
Wireless Manager ME 4.5 greatly
simplifies the PC-projector connec-
tion procedure. Simply press the
“Computer Search” button on the
supplied remote control and the
projector locates all live-mode
ready PCs in the area. All you do
is select the desired PC-to-projector connection.

Wireless Prompter Function (Secondary Display Transmission) Selective Area Transmission
Multiple Source Live Mode
This allows transmission of content other than what’s dis-
played on your PC. For example, you can display text doc-
uments on your PC screen while projecting slide from your
Microsoft
®PowerPoint®presentation*1.
By using the area select window, you can specify the
necessary information alone from the computer screen,
and display it on the projection screen. You can simultaneously project a single computer’s
screen on up to eight projectors. This mode is useful
when a number of projectors are installed, for example,
in a large conference room, or when holding simultane-
ous presentations in several conference rooms.

Four-window style Index style
(Four thumbnails)Extended index style
(16 thumbnails)
Multi Live Mode
The PT-LB51NTU provides a host of convenient wireless functions, including
Wireless Prompter (Secondary Display Transmission), selective area trans-
mission and a 16-window index style that lets you project images from up\
to 16 PCs at the same time. Wireless transmission is possible from one PC
to a maximum of eight projectors at a time.

Wireless Manager Control Panel (Launcher) 
To begin wireless projection, simply use the control
panel (launcher) displayed in the PC window. Windows Vista™/Macintosh Compatibility 
Wireless Manager ME 4.5 is Microsoft®Windows
Vista™ compatible, and also allows wireless pro-
jection (in Live mode only) from a Macintosh com-
puter running Mac OS X (v10.4 or later). 
						

							
Daylight View 2
Crisp, Clear Images in a Well-Lit Room
Panasonic’s Daylight View 2 technology, which
helps project sharp, crisp images that are easy to
see even in brightly lit rooms. A built-in sensor
measures the ambient light, and the halftone
colour and brightness level are adjusted according-
ly in real-time.
Presentation Flexibility
Easy-to-Use Remote Control
The control range and dis-
tance have been extended
compared to previous mod-
els, and the buttons are now
larger and easier to use.
Blackboard Mode
This special picture mode allows the PT-LB51NTU
to project images onto an ordinary classroom or
conference room blackboard when a projection
screen is not available.
Ultra-Lightweight and Compact
At only 1.8 kg/1.9 kg*
2, PT-LB51 models won’t
weigh you down—even when you’re carry- ing with you a laptop. PT-LB51 projec-tors are 297 mm wide by 210 mmdeep—about the size of an A4sheet of paper—and only 57 mm
high. Each slips easily into a bag
or briefcase.
Quick Operation
Customizable Function Button
One frequently used function
can be assigned to this button
on the top panel of the projec-
tor for instant, pushbutton use.
Select from shutter, auto setup,
picture mode, freeze, and index
window functions.
Two-Second Speed Start
With Speed Start, the image appears in about two
seconds after you press the power button.
Auto Search
When a source is connected and you switch the
unit on, it automatically detects what kind of
source is connected and begins projection.
Real-Time Keystone Correction
The projector automatically senses if you adjust its
angle (vertical direction) during operation and
instantly makes whatever keystone correction is
necessary for optimum viewing.
Direct Power Off
You can disconnect the
power cable and move
the projector as soon as
your presentation is fin-
ished, because the cool-
ing fan keeps operating
until the lamp is cooled.

NOTES ON USE
• The projector uses a high-voltage mercury lamp that contains high internal pressure. This
lamp may break, emitting a large sound, or fail
to illuminate, due to impact or extended use.
The length of time that it takes for the lamp to
break or fail to illuminate varies greatly
depending on individual lamp characteristics
and usage conditions.
• The brightness of the lamp will gradually decrease with use.
• The projector includes consumable parts. The frequency of replacement for the lamp and
other consumable parts will increase if the
projector is subjected to extended, continuous
use. For details, please consult a service rep-
resentative.Ecology-Conscious Design
