Powering up the Projector and Adjusting the Image

1Remove the lens cap.

2Plug the power cord into the side of the projector, then plug it into your electrical outlet. A surge-protected power strip is recommended if power surges are common in your area.

•The fans turn on and run at low speed. After the projector has initialized, the Power LED (Figure 18 on page 21) lights solid green.

3Turn on the projector by pressing the power button on the remote or keypad. (You can set the projector to turn on auto- matically when it is powered on. See “Auto startup” on page 33.)

•The InFocus startup screen displays.

4If you connected a video player, turn it on.

•Press the video button on the keypad to display the image from your video player. (You can select a default source to determine which source the projector examines first during power-up for active video; see “Default Source” on

page 32.)

•Use the volume buttons to adjust the volume.

NOTE: Always use the power cord that shipped with the projector.

CAUTION: If the lamp LED remains solidly lit after the projec- tor has powered on, the lamp needs to be replaced. Refer to “Replacing the Projection Lamp” on page 39 for more information.
