When disposing of the used lamp unit, ask your nearest local authorities or dealer about proper disposal of the unit.Dispose of used batteries according to the instructions or your local disposal rules or guidelines. Cautions on use

To achieve a high picture quality

You achieve a high picture quality by drawing curtains or blinds over windows and turning off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen.

Depending on the conditions, the picture may wobble due to the heated air from the air exhaust port or heated or cooled air from the air conditioner. Take care to ensure that neither the exhaust from the projector or other equipment, nor air from any air conditioner blows on the front of the projector.

The projection lens is heated by the light from the luminous source, making the focus unstable in the period just after switching on. The focus will stabilize after 30 minutes elapsed with the image being projected.

Do not touch the surface of the projection lens with your bare hands. If the surface of the lens is contaminated by ngerprints or dirt, this will be magnied and projected onto the screen, degrading the picture.

LCD panel The LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. This is not a malfunction.When a still image is projected for a long period, the image may burn in to the LCD panel. In this case, project the white screen from the test patterns (

page 74) for at least one hour. Note, however, that it may not always be possible to fully eradicate the burned-in image.Precautions for use

Optical components If you are using the projector at a high-temperature environment or an environment which is dusty or full of cigarette smoke etc., the replacement cycle for optical components such as the the LCD panel and polarizer may reduce to as little as a year. For more information, please consult your dealer.

Lamp The projector luminous source is a mercury lamp with high internal pressure.A high-pressure mercury lamp has the following characteristics.

The brightness of the lamp will decrease with usage time.

An impact, scratch, or deterioration with usage may cause the bulb to burst loudly or reduce the service life.

The service life of the lamp varies greatly depending on the individual lamp and usage conditions. In particular, continuous use for periods of 24 hours or longer and frequent on/off switching of the power accelerate deterioration in the lamp and affect the lamp life.

In rare cases, the lamp can burst shortly after starting the projection.

The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit consistently. “When to replace the lamp unit” ( page 85)

If the lamp bursts, gas contained in the lamp is released in a form of smoke.

It is recommend that you store replacement lamp units for contingency.

It is recommended that you request a qualied technician to replace the lamp unit. Consult your dealer.Precautions for use ENGLISH - 17 Important Information LX1750 User Manual020-000638-01 Rev.1 (11-2013) Accessories Make sure that the following accessories are provided with your projector.
