Shutting down the projectorThe projector automatically displays a black screen after no active source is 
detected for 30 minutes. This black screen helps preserve the life of the pro-
jector. The image returns when an active source is detected or a remote or 
keypad button is pressed.Screen SaveYou can make the black screen appear after a preset number of minutes by 
turning on the Screen Save feature in the Settings>System menu. See 
page 38.Pow e r  S av eThe projector also has a Power Save feature that automatically turns the 
lamp off after no active sources are detected and no user interaction with 
the projector is performed for 20 minutes. By default, this feature is off. See 
page 38.Turning off the projectorTo turn the projector off, press the remote’s Pow e r button to place the pro-
jector in the Off state while it is running. When the Pow e r button is pressed 
twice (once to start the power-down process and a second time to verify that 
you want to power the projector off), the lamp turns off and the LED blinks 
green for one (1) minute while the fans continue to run to cool the lamp. 
While the LED is blinking green, the projector does not accept any keypad 
and remote control input.
When the lamp has cooled, the LED lights solid green and the fans slow 
down to minimal speed. To turn off the projector, toggle the power switch to 
the off position. 
You can also turn the projector off simply by toggling the power switch to 
the off position.
NOTE: Once the projector has been toggled off, you must wait for one (1) 
minute before turning the projector on again. This allows the lamp to prop-
erly cool. However, if the remote was used to power the projector to the Off 
state you do not need to wait one minute to turn it on again.
Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section. If it 
does not, troubleshoot the setup. 
The LED on top of the projector indicates the state of the projector and can 
help you troubleshoot. 
The following tables show common problems. In some cases, more than one 
possible solution is provided. Try the solutions in the order they are pre-
sented. When the problem is solved, you can skip the additional solutions.

Using the remote controlThe remote uses two (2) provided AA batteries. They are easily installed by 
sliding the cover off the remote’s back, aligning the + and - ends of the bat-
teries, sliding them into place, and then replacing the cover.
Caution: When replacing the batteries, be aware that using batteries other 
than the type provided with the projector may risk severe damage to the 
remote. When disposing of the batteries, be sure to do so in an environmen-
tally proper manner.
To operate, point the remote at the projector (not at the computer). The 
range of optimum operation is about 15 feet (4.5m).
Pressing the remote’s Pow e r button when the projector ’s Power toggle 
switch is in the Off position does not cause the projector to power up. You 
need to put the projector ’s Power toggle switch in the On position to let the 
remote power on the projector.
When the projector is running, you can press the remote’s Pow e r button to 
place the projector in the Off state (see page 21 for shutdown info) and 
power it off.
Press the remote’s Menu button to open the projector ’s menu system. Use 
the arrow buttons to navigate, and the Select button to select features and 
adjust values in the menus. See page 34 for more info on the menus.
The remote also has Vo l u m e and Mute buttons to control the sound, and 
Video and Computer buttons to switch between sources.
Two presentation-specific features are also provided. Use the Blank button 
to display a blank screen instead of the current slide (you can choose which 
color is displayed, see page 39); use the Effect button to invoke a user-defin-
able action, such as freeze, or change your aspect ratio for viewing DVDs 
(see page 39 to learn to program this button).
Previous and Next buttons allow you to navigate through your PowerPoint 
presentation while in Slide Show mode. Connect the USB connector on the 
provided computer cable to your computer to use these buttons. When you 
do this for the first time, the Add New Hardware wizard may appear. See 
page 15 for details on loading the correct USB drivers. Troubleshooting the remote
 Make sure the batteries are installed in the proper orientation and are 
not dead.
 Make sure you’re pointing the remote at the projector or the screen, not 
the computer, and are within the remote range of 15 feet (4.5m). For 
best results, point the remote at the projector.
 If you are trying to advance PowerPoint slides, make sure the USB 
cable is connected. If using a USB cable, make sure the correct drivers 
are installed.

Using the audio Using the projector’s speakersTo use the projector ’s speaker, connect your source to the Audio In connec-
tors (L and/or R) on the projector ’s composite connectors. 
To adjust the volume, press the Vo l u m e buttons on the keypad or remote.
To mute the sound, press the Mute button on the remote. 
Troubleshooting Audio
If you aren’t hearing the audio, check the following:
 Make sure the audio cable is connected.
 Make sure mute is not active (press the Mute button on the remote). 
 Make sure the volume is turned up enough. Press the Vo l u m e  button 
on the keypad or remote.
 Make sure the correct source is active.
 Make sure that you are connected to an “audio out” connector on the 
source as opposed to a “line-in” or “microphone” connector.
 Adjust the audio source.
 If playing a video, make sure the playback has not been paused.Connecting external speakersThe projector can be attached to external amplified speakers by connecting a 
3.5mm stereo audio cable from the Audio Out connector on the projector to 
the amplified speakers. Alternatively, you can bypass the projector ’s audio 
system and connect the audio directly from your source to a stereo or home 
theater system.
