How to Clean the Airflow Sensor 
IMPORTANT: The air flow sensor is an extremely sensitive component and must be 
handled with extreme care. Any pressure greater than 20 P.S.I. applied to the sensor 
may result in permanent damage to the sensor. 
 WARNING  
Ensure that the air flow sensor itself does not come into 
contact with any foreign objects. 
Use pressurized air (canned air) to blow away the contaminants covering the sensor. 
Short, indirect bursts are recommended in order to minimize the overall pressure to 
the sensor itself during cleaning. 
 WARNING  
DO NOT insert air nozzle/straw into the holes of the air 
flow sensor. 
How to Re-install the Airflow Sensor 
Ensure the sensor is repositioned correctly according to your specific model. Follow 
the removal steps in reverse order. 
 WARNING  
Proper face shield and protective gloves are required if the lamp 
module is removed from the projector. 
 
The IR Remote Keypad uses two AA size, 1.5V batteries (preferably alkaline). To 
install new batteries:  
1) Open the battery 
compartment at the 
backside of the keypad by 
placing your thumb in the 
oval depression and sliding 
the cover out about ½ inch. 
See Figure 4.2. Remove 
the old batteries and 
properly discard. Wait a 
minute or two.  
2) Place the new batteries in the compartment, orienting the positive/negative of each 
battery according to the labels in the compartment. When the batteries are in place, 
replace the cover by placing the cover ½ inch from its closed position and slide it into 
place. Do not force the cover.  
NOTE: Always wait a minute or two when replacing batteries so that the internal 
electronics discharge and can recognize the change.

A bubble lamp permanently mounted inside its own protective assembly provides the 
high brightness of your projector. Using this module beyond its warranted life is not 
recommended—changes in the quartz of the bulb can lead to reliability problems, 
poor performance or sudden lamp expiry. The filter should always be changed when 
the lamp is replaced, or sooner in dusty environments. 
The lamp module is calibrated for maximum performance and brightness in this 
projector. Do not attempt to re-align or adjust the lamp module. 
How old is the lamp? 
The number of hours logged on the current lamp appears both in the Lamp menu and 
the Status menu. In the Status menu, do not confuse “Lamp Hours” with “Lamp 
Counter” which indicates the number of hours logged during the current rental period 
only and is normally used for rental projectors only. 
NOTE: As the lamp nears its limit (as set in Lamp Limit), a message can appear on 
screen to warn that the lamp needs to be replaced. The LED’s next to the built-in 
keypad will flash “LP” when lamp time has expired.  To ensure this warning 
appears, enter a checkmark in the Lamp Message checkbox located in the Lamp 
submenu. 
 
TOOLS:  A Phillips #2 screwdriver is required. All access panels’ screws are ¼-turn 
to lock/unlock. 
Warnings 
 A qualified service technician must perform lamp replacement. 
 Cool the lamp completely and handle by the housing only. 
 Install the correct wattage lamp supplied by Christie (see above) and read the 
Lamp Replacement procedure in its entirety before proceeding.
