Notes on replacing the lamp unit

Because the lamp unit in this projector incorporates a metal halide lamp, the temperature inside the lamp rises during use and the lamp becomes very hot. After turning off the MAIN POWER switch and disconnecting the power cord from the wall socket, wait for the lamp to cool down before replacing the lamp unit.

Take extreme care when handling the removed lamp unit, as it contains gas under high pressure and can easily become damaged if it is struck against hard objects or dropped.

The old lamp unit may shatter if it is handled roughly after removal.

Ask an authorized waste disposal agency to dispose of the old lamp unit.

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

NOTE:

The projector is not supplied with a replacement lamp unit. Please ask your dealer for details. Lamp unit product no.: ET-LA095

CAUTION: Do not use any lamp unit other than the one with the product number indicated above.
