WARNING: Be extremely careful when removing the lamp module. In the unlikely event that the bulb 
ruptures, small glass fragments may be generated. The lamp module is designed to contain these 
fragments, but use caution when removing the lamp module. 
 
4. Loosen the two non-removable screws on the outside of the module (Figure 40). 
CAUTION: Never operate the projector with the lamp door open or removed. This disrupts the airflow 
and causes the projector to overheat.

Cleaning the Projection Lamp Filter Screens 
In dirty or dusty environments, the dust filter screens on the lamp module can become clogged, 
causing high temperatures inside the lamp module. These high temperatures can cause 
premature lamp failure. Routine maintenance to remove dust and dirt from the screens lowers the 
lamp operating temperature and prolongs lamp life. To maximize lamp life you may want to clean 
the screen every 250 hours. 
1. Remove the lamp module. Refer to “Replacing the...

Viewing the HD110 Projector 
 
Depending on what is viewed the most the user must decide if a 4:3 (1.33:1) or 16:9 (1.85:1) 
aspect ratio screen is best. Both screen aspect screens will display all images, but the highest 
resolution images are obtained when viewing the image in its correct aspect ratio screen. If the 
image is projected on a large wall (not recommended but white color preferred) then all 
combinations are possible.
