Replacing the Lamp  
Replace the lamp with a new one if a message displayed on the projected image or the LAMP/  
COVER indicator notifies you to replace the lamp (pages 33, 34).  
Use an LMP-C280 projector lamp (not supplied) for replacement.  
1 Turn off the projector, and disconnect  
Caution  
the AC power cord from a wall outlet.  
• The lamp remains hot after the projector is  
turned off. If you touch the lamp, you may  
burn your finger. When you replace the  
lamp, wait for at least an hour after  
turning off the projector for the lamp to  
cool sufficiently.  
2 When the lamp has cooled  
sufficiently, open the lamp cover by  
loosening 3 screws.  
• Do not allow any metallic or inflammable  
objects into the lamp replacement slot after  
removing the lamp, otherwise it may cause  
electrical shock or fire. Do not put your  
hands into the slot.  
Notes  
If the lamp breaks, contact qualified  
Sony personnel. Do not replace the lamp  
yourself.  
• When removing the lamp, be sure to pull it  
out straight, by holding the designated  
location. If you touch a part of the lamp other  
than the designated location, you may be  
burned or injured. If you pull out the lamp  
while the projector is tilted, the pieces may  
scatter if the lamp breaks any may cause  
injury.  
You can remove the lamp cover for a  
while when installing on the ceiling.  
Take care to prevent the lamp cover from  
falling down, as it is not fixed.  
Do not apply pressure to the lamp cover  
while it is open.

When a message appears on the projected image, clean the air filter (page 34).  
If the dust cannot be removed from the air filter even after cleaning, replace the air filter with  
a new one. For details on a new air filter, consult with qualified Sony personnel.  
Caution  
If you neglect to clean the air filter, dust may accumulate, clogging it. As a result, the  
temperature may rise inside the unit, leading to a possible malfunction or fire.  
The air filter consists of 2 filters.  
1 Turn off the projector, and disconnect  
the AC power cord from the AC outlet.  
Upper filter: Black  
2 Draw out the air filter cover.  
Lower filter: Gray  
Air filter cover  
4 Attach the air filter cover to the unit.  
Note  
Be sure to attach the air filter cover firmly.  
Incorrect attachment of the cover may  
cause a malfunction.  
Note  
If you remove the air filter cover when  
power is turned on and the AC power cord  
is not removed from the AC outlet, avoid  
touching the fan inside the unit, as it may  
cause injury.  
3 Clean the air filter with a vacuum  
cleaner.  
Remove the filter holder to remove the  
air filter.

Projection Distance and Lens Shift Range  
The following describes the projection distance and height from lens center to bottom of screen  
by each projected screen size.  
The projection distance is the distance between the front of the lens and the surface of the  
projected image.  
Height H is the height from the bottom of the projected image (top for ceiling mount) to A  
(determined by drawing a perpendicular line from lens center to projected image surface). For  
this unit, the same projection distance calculations apply to both floor and ceiling installation.  
Caution  
Never mount the projector on the ceiling or move it by yourself. Be sure to consult with  
qualified Sony personnel (charged).
