7Turn on your computer.
•The computer image should display on the projection screen.
•The computer source indicator LED displays a solid green indicating the computer source is active (Figure 22).
•If necessary, use the brightness buttons on the remote con- trol or keypad to adjust the brightness. You can make fur- ther adjustments to the image from the projector’s on- screen menus. To open the menus, press the menu button on the remote control or keypad. Then select the Display menu or the Image menu. For more information about the menus, see page 32.
•If you don’t want to hear the sound from your computer or video player, press the mute button. (Pressing mute does not mute the microphone.)
Turning Off the Projector
If you want to turn off the projector for a short period of time, press the standby button on the remote control or keypad. This turns off the lamp but keeps the projector running. The power/ standby indicator LED (Figure 22) blinks green while the projec- tor is in standby. To exit standby mode, press the standby button once. (It takes several seconds for the projection lamp to reach full power and project the image again.)
To completely power off the projector, press the “O” side of the power switch. If you want to turn the projector back on immedi- ately, you must allow about 45 seconds for the lamp to cool. The lamp won’t light if it’s too hot.
NOTE: With some computers, the order in which you power up the equipment is very important. We recommend that you always turn on the computer LAST. Turn on all other pieces of equipment (including the computer’s moni- tor) before you turn on the com- puter.
NOTE: When you disconnect the projector after you have switched it off, always remove the power cord from the electrical outlet first, then remove it from the projector.
