Lamp Replacement

To replace either of the lamps, follow all instructions provided on page 107.

Be sure to replace the lamp when the following is displayed on the screen:

If you continue to use the lamp after the lamp has reached the end of its usable life, the

lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not

touch them as the pieces of glass may cause injury.

If this happens, contact your dealer for lamp replacement.

Important Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source.

A characteristic of mercury lamps is that brightness gradually decreases with age. Also

repeatedly turning the lamp on and off will increase the possibility of reduced brightness.

CAUTION:

When removing the lamp from a ceiling-mounted projector, make sure that no

one is under the projector. Glass fragments could fall if the lamp has been

burned out.
