Chapter 1 Preparation — Precautions for use

rrDo not touch the surface of the projection lens with your bare hands.

If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen.

Attach the supplied lens cover to the optional projection lens when not using the projector.

rrDLP chips

ffThe DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that such phenomena does not indicate malfunction.

ffDirecting a high-power laser beam onto the projection lens surface can damage the DLP chips.

rrDo not move the projector or subject it to vibration or impact while it is operating.

Doing so may shorten the life of the built-in motor.

rrLamp

The light source of the projector is a high-pressure mercury lamp. A high-pressure mercury lamp has the following characteristics. ffThe luminance of the lamp will decrease by duration of usage.

ffThe lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or degradation due to cumulative runtime.

ffThe lamp life varies greatly depending on individual differences and usage conditions. In particular, frequent on/off switching of the power greatly deteriorate the lamp and affects the lamp life.

ffContinuous use for over one week will deteriorate the lamp. The degradation of the lamp due to continuous use can be reduced by using the [PROJECTOR SETUP] menu → [LAMP RELAY].

ffIn rare cases, the lamps burst shortly after projection starts.

ffThe risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit regularly.

(“When to replace the lamp unit” (x page 146), “How to replace the lamp unit” (x page 147))

ffIf the lamp bursts, gas contained inside of the lamp is released in the form of smoke. ffIt is recommended that you store the replacement lamp unit as a contingency.

rComputer and external device connections

ffWhen connecting a computer or an external device, read this manual carefully regarding the use of power cords and shielded cables as well.
