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.
Ensure that the air flow sensor itself does not come into
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.
DO NOT insert air nozzle/straw into the holes of the air

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.
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.
