correctly positioned on the screen. 
  
l
To focus the image, rotate the focus ring (the inside ring on the 
lens).

If you need to raise or lower the image on the screen, extend or retract 
the two feet at the bottom of the projector as follows:
1. Stand behind the projector and support the front of it while you 
lift up on the foot adjust levers, located above the feet. This 
unlocks the adjustable feet so they can move up and down. Don’t 
let the projector drop.
F
Caution: Don’t hold or lift the projector by its lens. This can damage 
the lens.
2. While lifting the levers, raise or lower the projector until the screen 
image is correctly positioned.
3. Release the levers to lock the feet in their new position.
4. If you want to fine-tune the height of the projector, turn the 
adjustable feet clockwise to raise the height, and counterclockwise 
to lower the height.

Resize Button 
The Resize button lets you select the projection method for certain 
types of image signals input from a computer.
With images below SVGA size (800
´600 pixels) on the PowerLite 
5300, or below XGA size (1024
´768 pixels) on the PowerLite 7200 
or PowerLite 7300, you can choose from two projection methods. 
Either display the image in the center of the projection area or display 
the image full size.
You can also choose from two projection methods with images greater 
than SVGA size (PowerLite 5300) or XGA size (PowerLite 7200 or 
PowerLite 7300). Either project a portion of the image or project the 
entire image in a compressed format. The projector automatically 
reduces the image size to the projector’s maximum resolution.
The Resize button cannot be used with SVGA (800
´600) on the 
PowerLite 5300, or with XGA (1024
´768) on the PowerLite 7200 or 
PowerLite 7300.
There’s a Resize button on both the control panel and remote 
control.
Sleep Mode
Sleep mode conserves electricity by automatically turning off the lamp 
after the projector has not been used for 30 minutes. In sleep mode, 
the projector’s power status indicator is orange and only a minimum 
amount of the projector’s circuitry remains on. This conserves

Using the Remote Control 
The remote control uses a line-of-sight infrared signal. To use the 
remote control, point it towards one of the remote control receivers 
located at the front and back of the projector. (See page 58.)
You can use the remote control up to about 32.8 feet (10 meters) from 
the projector. (This distance may be shorter if the remote control 
batteries are low.) You must also be within a 
± 30
° angle from the front 
or rear sensor.

Note: The projector may not respond to remote control commands in these 
conditions: ambient light is too bright; a certain type of fluorescent light is 
present; a strong light source (such as direct sunlight) shines into the 
infrared receiver; or other equipment emitting infrared energy is present 
(such as a radiant room heater). Correct these conditions to use the remote 
control or control the projector from a computer.
