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.

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.

% Insert the battery holder.

NOTE:

B Do not drop the remote control unit.

B Keep the remote control unit away from liquids.

B Remove the battery if not using the remote control unit for long periods.

B Use only CR2025 batteries as replacement batteries.

NOTE:

B If the remote control unit is held so that it is facing directly in front of the front or rear remote control signal receptors, the operating range is within approximately 7 m

(23´) from the surfaces of the receptors. Furthermore, the remote control unit can be operated from an angle of ±30° to the left or right and ±15° above or below the receptors.

B If there are any obstacles in between the remote control unit and the receptors, the remote control unit may not operate correctly.

B If strong light is allowed to shine onto the remote control signal receptor, correct projector operation may not be possible. Place the projector as far away from light sources as possible.

B If facing the remote control unit toward the screen to operate the projector, the operating range of the remote control unit will be limited by the amount of light reflection loss caused by the characteristics of the screen used.

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.

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

AUTO setting above is selected, this projector will recognise the detector signal and automatically switch the aspect ratio to 16:9 in order to project the picture.

NGLISH

-39



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.

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.

Replacing the lamp unit

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.

Projection dimensions calculation methods

If the screen size (diagonal) is SD (m), then the following formula is used to calculate the projection distance for the wide lens position (LW) and the projection distance for the telephoto lens position (LT).

4:3

SD

LW/LT SW

PT-LC80E PT-LC76E / PT-LC56E

LT=0.036xSD/0.0254-0.037

LT=0.037xSD/0.0254-0.038

For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.
