• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the
projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool
before handling.
• 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.

[HIGH ALTITUDE] can cause the projector to overheat and the protector could shut down. If this
happens, wait a couple of minutes and turn on the projector.

[HIGH ALTITUDE] can cause the lamp to overcool and the image to flicker causing the image to
