NOTE TO SERVICE: PERSONNEL

UV-RADIATION PRECAUTION

;///////////////////

The light source, metal halide lamp, in the LCD

projector emits small amounts of UV-Radiation.

AVOID DIRECT EYE AND SKIN

EXPOSURE.

To ensure safety please adhere to the following:

1.

Be,

sure to wear sun-glasses when servicing the
projector with the lamp
turned “on” and the top
enclosure removed.

2. Do not operate the lamp outside of the lamp
housing.

Since small amounts of UV-Radiation are emitted
from an opening between the duct cover and the

lamp housing, it is recommended to place the LENS

CAP on the opening during servicing to avoid eye

projector operation. To prevent injury, do not touch these areas until they have sufficiently

cooled.

l

Allow at least 10 cm of space between the cooling fan (exhaust vent) and the other nearest

wall or obstruction.

l

If the cooling fan becomes obstructed, a protection device will automatically turn off the

projector lamp.

This

does not indicate a malfunction. Remove the projector plug from the

wall outlet and wait 10 minutes. Then turn on the power by plugging the cord back in. This

will return the projector to its normal mode.

Note:

l

The signal transmitter does not fun&on when the optional

The laser pointer on the remote control emits

a laser beam from the laser light window
shown in the figure to the left. The laser
emitted is a class II laser; therefore, do not

look

into the laser window or shine the laser
beam on yourself or other people. The two
marks to the left are the caution labels for the
laser beam.
Always use the laser pointer at temperatures
