MaintenanceCleaning the Lens1
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
 Avoid using an excessive amount of cleaner, and don’t apply the 
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh 
chemicals might scratch the lens.
2
Lightly wipe the cleaning cloth over the lens in a circular motion. If you 
don’t intend to use the projector immediately, replace the lens cap.
Replacing the Projection LampThe lamp hours used timer in the About menu counts the number of hours 
the lamp has been in use. Twenty hours before the lamp life expires, the 
message “Change lamp” appears on the screen at startup. If the maximum 
lamp time is exceeded, the lamp will not light. In this case, after replacing 
the lamp you must reset the lamp hours by simultaneously pressing both 
Vo l u m e buttons on the keypad and holding them for 10 seconds. 
NOTE: You can order new lamp housings from your dealer. See the Packing 
list for information. Use only a replacement lamp with the same type and 
rating as the original lamp.1
Turn off the projector and unplug the power cord. 
2
Wait 30 minutes to allow the projector to cool thoroughly.
3
Turn the projector on its side so that the lamp door is facing you. Using a 
flat-blade screwdriver, gently pry the lamp door from the projector by 
placing the screwdriver blade into the space between the top of the lamp 
door and the projector.

Loosen the two captive screws that attach the lamp housing to the pro-
jector.
5
Detach the lamp connector from the projector by depressing the locking 
tab on the connector and lightly pulling it free.
WA R N I N G:
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 frag-
ments, 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 prod-
uct has a lamp which contains a very small amount of mercury. Dis-
pose of it as required by local, state or federal ordinances and 
regulations. For more information see www.eiae.org.
6
Carefully remove the lamp housing. Dispose of the lamp in an environ-
mentally proper manner. 
7
Install the new lamp housing and tighten the screws.
8
Re-attach the lamp connector to the projector. The locking tab should 
engage when the connector is fully plugged in.
9
Replace the lamp door.
10
Plug in the power cord and toggle the Powe r switch to turn the projector 
back on.

Cleaning the Lamp Housing ScreensIn dirty or dusty environments, the two dust filter screens in the lamp hous-
ing 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 every 250 hours. 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 lockThe projector has a security lock for use with a cable lock system. Refer to 
the information that came with the lock for instructions on how to use it.

Red LED Behavior
Explanation
One (1) blink The lamp wont strike after five (5) 
attempts. Check the lamp and lamp door 
installations for loose connections.
Two (2) blinks The lamp counter hours have exceeded 
lamp life hours. Replace the lamp and 
reset the lamp hours counter.
Three (3) blinks The projector has shut down. Check to 
see if the lamp door is open. If the lamp 
door is closed, toggle off the projector 
and wait one minute, then toggle the pro-
jector on again. If the lamp does not strike 
after one minute, replace the lamp. Con-
tact your dealer (see page 30) for repair if 
replacing the lamp does not solve the 
problem.
Four (4) blinks The fan has failed. Contact your dealer 
(see page 30) for repair or replacing the 
fan.
Five (5) blinks The projector is overheating. Check for a 
blocked air vent. Contact your dealer (see 
page 30) for repair if clearing the air vents 
does not solve the problem.
