WARNING:

To avoid burns, allow the projector to cool for at least 30 minutes before you replace the lamp.

Do not drop the lamp housing or touch the glass bulb! The glass may shatter and cause injury.

Be extremely careful when removing the lamp housing. In the unlikely event that the bulb ruptures, small

glass fragments may be generated. The lamp housing is designed to contain these fragments, but use

caution when removing the lamp housing. Before replacing the lamp, clean the lamp compartment and

dispose of cleaning materials. Wash hands after lamp replacement. This product has a lamp, which contains

a very small amount of mercury. Dispose of it as required by local, state or federal ordinances and

regulations. For more information see www.eiae.org

Dispose of the lamp in an

the Power switch to turn the projector

Cleaning the Lamp Housing Screens

In dirty or dusty environments, the two dust filter screens in the lamp housing

can become clogged, causing high

temperatures and premature lamp

failure. Routine maintenance to

remove dust from the screens

lowers the lamp operating

temperature and prolongs lamp life.

To maximize lamp life, you should

clean the screen at least every 250

hours depending upon

environmental conditions. The

dirtier or dustier the environment,

the more often you should clean

the screens.

1 Remove the lamp housing.

2 Examine the dust filter screens on the lamp housing. If necessary, use a vacuum cleaner set on low power

to clean the screens. Be careful not to disturb any internal components when cleaning the screens.

3 Replace the lamp housing and lamp door.

Using the security lock

The projector has a security lock for use with a

PC Guardian Cable Lock System. Refer to the

information that came with the lock for instructions

on how to use it.
