Panasonic LCD Projector PT-L730NTU Operating Instructions

							41
Basic Operation
NOTE:
•   S1 video signals
S1 video signals are a type of video
signal with an aspect ratio of 16:9
which include a detector signal. This
detector signal is output by some
sources such as wide-vision video
decks. If the AUTO setting above is
selected, this projector will recognize
the detector signal and automatically
switch the aspect ratio to 16:9 in order
to project the picture.
•  This projector is equipped with an
aspect ratio selection function.
However, if a mode which does
not match the aspect ratio of the
input signal is selected, it may
affect the quality of viewing of the
original picture. Keep this in mind
when selecting the aspect ratio.
•   If using this projector in places
such as cafes or hotels with the
aim of displaying programs for
viewing for a commercial purpose
or for public presentation, note
that if the aspect ratio (16:9)
selection function is used to
change the aspect ratio of the
screen picture, you may be
infringing the rights of the original
copyright owner for that program
under copyright protection laws.
•   If a normal (4:3) picture which was
not originally intended for wide-
screen viewing is projected onto a
wide screen, distortion may occur
around the edges of the picture so
that part of the picture is no longer
visible. Such programs should be
viewed in 4:3 mode to give proper
consideration to the aims and
intentions of the original program ’s
creator.
RESIZING
This should normally be set to  “ON ”. (This setting is only for signals
which have lower resolutions than
the LCD panels. Refer to page 
60
for details.)
ON
The pixel resolution of the input
signal is converted to the same
resolution as the LCD panels before
being projected. For signals with
lower resolutions, gaps in the pixels
are automatically interpolated into
the picture before it is projected.
This may sometimes cause
problems with the quality of the
picture.
OFF
The picture signal is projected at its
original resolution, with no pixel
conversion. The projected picture
will be smaller than normal, so
adjust the zoom setting or move the
projector forwards or backwards to
adjust the picture size if necessary.
If set to  “OFF ”, some features, such
as D.ZOOM (digital zoom) or
keystone distortion correction will
not function.
A U TO SETUP
This item functions in the same way
as the AUTO SETUP button on the
remote control unit. (page  15)
FRAME LOCK 
If the picture ’s condition is bad while
a RGB moving picture signal is
projected, set the FRAME LOCK to
“ ON ”. Refer to page  60 on
compatible RGB signals.

SHUTTER or WEB PASSWORD
functions work, press the ENTER
button.SHUTTER
The shutter function can be used to
momentarily turn off the picture and
sound from the projector when the
projector is not being used for short
periods of time, such as during
breaks in meetings or when carrying
out preparation. The projector uses
less power in shutter mode than it
does in normal projection mode.
OSD
ON
The current input name is displayed
in the top-right corner of the screen
when the input signal is changed.
OFF
Use this setting when you do not want
the current input name to be displayed.
AUTO KEYSTONE
This should normally be set to ON.
ON
During automatic setup, the angle of
tilt of the projector is detected and
vertical keystone distortion is
corrected automatically.
OFF
Use this setting when you do not
want automatic keystone correction
to be carried out during automatic
setup, such as when the screen
itself is at an angle.
RGB/YPbPr
This setting is valid when 750p,
HDTV60, HDTV50, 525p, 625i and
525i signals are being input. Select
the setting in accordance with the
input signal.
The RGB/YPbPr item is displayed
when an RGB1 IN or RGB2 IN
connectors has a signal being input.

AU TO RGB IN
This should normally be set to OFF.
ON
If the input source has been
changed to RGB, automatic setup
automatically detects whether the
RGB1 or the RGB2 connector is
being used to input the signal, and
the signals from the connector that it
detects are then projected.
(If a picture is being projected, the
signal source is not automatically
changed.)
OFF
Use this setting when you do not
want the signal source to be
changed automatically during
automatic setup.
RGB2 SELECT
This setting is used to select the
function of the RGB2 IN/RGB1 OUT
connector. 
B ACK COLOR
This sets the color which is
projected onto the screen when no
signal is being input to the projector.
FR ONT/REAR
This setting should be changed in
accordance with the projector
setting-up method.
Set to  “FRONT ” when using a
normal reflective screen with the
projector positioned in front of the
screen, and set to  “REAR ” when
using a translucent screen with the
projector positioned behind the
screen.
DESK/CEILING
This setting should be changed in
accordance with the projector
setting-up method.
Set to  “DESK ” when setting up the projector on a desk or similar, and
set to 
“CEILING ” when suspending
the projector from the ceiling using
the ceiling bracket which is sold
separately.
LAMP P OWER
This setting changes the lamp
brightness. When set to  “LOW ”, the
luminance of the lamp is reduced, but
the projector uses less power, and
the operating noise is also reduced.
This can help to extend the lamp ’s
operating life. If using the projector in
small rooms where high luminance is
not required, it is recommended that
you set the LAMP POWER to  “LOW ”.
LAMP  RUN TIME
This setting displays the usage time
for the lamp unit which is currently
being used. If the lamp unit is
replaced in the way described on
page  53, the cumulative usage time
for the lamp unit will be reset to
zero.
NOTE:
• The lamp ’s operating life varies
depending on the usage conditions
(such as the LAMP POWER setting
and the number of times the power
is turned on and off). 
FAN CONTROL
If using of this projector at high
elevations (above 1400 m), set the
FAN CONTROL to  “HIGH ”.
