Notes on use

In order to get the best picture quality

Draw curtains or blinds over any windows and turn off any
fluorescent lights near the screen to prevent outside light or
light from indoor lamps from shining onto the screen.

Do not touch the surfaces of the lens with your bare
hands.

If the surface of the lens becomes dirty from fingerprints or
anything else, this will be magnified and projected onto the
screen. Moreover, when not using the projector, retract the
lens and then cover it with the accessory lens cover.

About the screen

Do not apply any volatile substances which may cause
discolouration to the screen, and do not let it become dirty or
damaged.

About the lamp

The lamp may need to be replaced earlier due to variables
such as individual lamp characteristics, usage conditions and
the installation environment, especially when the projector is
subjected to continuous use for more than 10 hours or the
power is frequently turned on and off.

Before use

Cautions when moving the projector

Be sure to attach the lens cover before moving the
projector.

The projection lens is extremely susceptible to vibration and
shocks. When moving the projector, use the accessory
carrying bag. When placing the projector inside the carrying
bag, position it so that the lens is facing upward.

Cautions regarding setting-up

Avoid setting up in places which are subject to vibration
or shocks.

The internal parts can be damaged, which may cause
malfunctions or accidents.

Do not set up the projector near high-voltage power lines
or near motors.

The projector may be subject to electromagnetic interference.

If installing the projector to the ceiling, ask a qualified
technician to carry out all installation work.

You will need to purchase the separate installation kit (Model
No.ET-PKC80). Furthermore, all installation work should only
be carried out by a qualified technician.

If using this projector at high elevations (above 1400 m),
set the FAN CONTROL to HIGH. (Refer to page 43.)

Failure to observe this may result in malfunctions.

Connections

Notes on connections

B

Read the instruction manual for each system component carefully before connecting it.

B

Turn off the power supply for all components before making any connections.

B

If the cables necessary for connecting a component to the system are not included with the component
or available as an option, you may need to fashion a cable to suit the component concerned.

B

If there is a lot of jitter in the video signal which is input from the video source, the picture on the
screen may flicker. In such cases, it will be necessary to connect a TBC (time base corrector).

B Refer to the list on page 58 for details on compatible signals which can be

input to the projector.

B

Only one audio system circuit is available for the AUDIO IN L-R jacks, so if you wish to
change the audio input source, you will need to remove and insert the appropriate plugs.

B Press the MENU button to return to the previous screen.

NOTE:

B

If you press the AUTO SETUP button after correcting the keystone distortion

manually, the automatic keystone correction function will operate and the corrected

picture will return to its previous incorrect condition. To prevent this from happening,

you can set “AUTO KEYSTN” in the OPTION1 menu to “OFF”. (Refer to page 42.)

B

Vertical keystone distortion can be corrected to

±30°

of the angle of tilt. Horizontal

keystone distortion can be corrected to

±20°

of the angle of tilt for the PT-LC80E.
However, the greater the correction amount, the more the picture quality will
deteriorate, and the harder it will become to achieve a good level of focus. To obtain
the best picture quality, set up the projector and screen in such a way that the amount
of keystone correction required is as minimal as possible.

The picture size will also change when correction of keystone distortion is carried out.

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 recognise the
detector signal and automatically
switch the aspect ratio to 16:9 in

Adjustments and settings

40-ENGLISH

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 58
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),
keystone distortion correction or
INDEX WINDOW will not function.

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 58 on
compatible RGB signals.

NOTE:

B

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.

B

If using this projector in places
such as cafes or hotels with the
aim of displaying programmes 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
programme under copyright
protection laws.

B

If a normal (4:3) picture which was
not originally intended for wide­screen 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 programmes should
be viewed in 4:3 mode to give
proper consideration to the aims
and intentions of the original
programme’s creator.

Warning

When replacing the lamp, allow it
to cool for at least one hour
before handling it.

B The lamp cover gets very hot,

and contact with it can cause
burns.

Notes on replacing the lamp
unit

B The light generating lamp is

made of glass, so dropping it or
allowing it to hit hard objects may
cause it to burst. Be careful when
handling the lamp.

B After having removed the old

lamp, carelessly discarding it can
cause the lamp to burst. Dispose
of the lamp with the same care
that would be taken with a
fluorescent light.

B A Phillips screwdriver is

necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.

Lamp unit replacement
period

The lamp is a consumable product.
Even when the full life of the bulb
has not been exhausted, the
brightness of the light will gradually
decline. Therefore periodic
replacement of the lamp is
necessary.
The intended lamp replacement
interval is 2000 hours, but it is
possible that the lamp may need to
be replaced earlier due to variables
such as a particular lamp’s
characteristics, usage conditions
and the installation environment.
Early preparation for lamp
replacement is encouraged.
A lamp that has exceeded 2000
hours of use has a much greater
chance of exploding. In order to
prevent the lamp from exploding,
the lamp will be automatically shut
off when 2000 hours of use have
been reached.

NOTE:

B The projector is not supplied

with a replacement lamp unit.

Please ask your dealer for

details. Lamp unit product

no.: ET-LAC80

CAUTION:

B Do not use any lamp unit other

than the one with the product

number indicated above.

NOTE:

B The usage hours explained

above are for use when the
HIGH setting has been
selected for LAMP POWER in
the OPTION2 menu. If the
LOW setting is selected, the
brightness of the lamp will be
less and life of the lamp can be
extended.

B While 2000 hours is the

intended replacement interval,
it is not a period of time
covered by warranty.

NOTE:

B If the lamp usage time has passed 2000 hours (when LAMP POWER

has been set to “HIGH”), the projector will switch to standby mode after
approximately 10 minutes of operation. The steps ) to - on the next
page should thus be completed within 10 minutes.
