Adjusting the Volume
You can use the buttons on the remote control or projector to increase 
or decrease the volume for the projector’s built-in speaker or external 
speakers connected to the projector. Press the   button to increase 
the volume, or the   button to decrease it. A volume gauge appears 
on the screen while the volume is being adjusted.
Shutting Down the Projector
When you’ve finished using the projector, follow the recommended 
procedure to shut it down. This extends the life of the lamp and 
protects the projector from possible overheating. 
1. If you’re using a computer, shut it down first.
2. To turn off the projector, press the P 
Power button on the 
projector or remote control.
You see this confirmation message: 
(If you don’t want to turn it off, press 
any other button or wait a few 
seconds until it disappears.)
note
You can also adjust the 
volume using the projector’s 
Setting menu. See page 57 
for details.
You must adjust the volume 
separately for each input 
source.

caution
Never unplug the 
projector without first 
turning it off, as described 
in this section. If the 
Direct Power ON feature 
has been enabled (as 
described on page 60), 
you must still follow the 
steps in this section to turn 
the projector off. 
						

							42Projecting3. Press the P 
Power button again. The lamp turns off, and the 
Power light flashes orange for about 20 seconds as the projector 
cools down. When the projector has cooled, it beeps twice to 
indicate that power is off. The 
Power light stays orange and the 
exhaust fan shuts off.
If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the P 
Power button.
4. Press up on the blue foot release lever and lower the projector to 
retract the front adjustable foot, as shown.
5. Replace the lens cap and unplug the power cord.
6. Turn off and disconnect any equipment plugged into the 
projector.
note
When the projector has not 
received any input signals for 
30 minutes, it automatically 
turns off the projector lamp 
and enters “sleep mode.” This 
conserves electricity, cools the 
projector, and extends the life 
of the lamp. If you are done 
using the projector, unplug 
the power cord. If you want 
to start projecting again, press 
the P 
Power button. You 
can turn sleep mode on or off 
through the Extended menu. 
See page 59.
caution
To avoid damaging the 
projector or lamp, never 
unplug the power cord 
when the Power light is 
green or flashing orange.

Using the Remote Control
The remote control lets you access your projector’s features from 
anywhere in the room—up to 20 feet away. For example, you can turn 
the projector on and off, freeze the presentation, zoom in on a portion 
of your image, and access the menu system. (The projector menus let 
you adjust many projector settings; see Chapter 4.)
If you’re using a computer and you’ve connected the mouse cable 
as described in Chapter 1, you can use the remote control as a wireless 
mouse.
When using the remote control, stand within 20 feet of the projector. 
Point the remote control either at the front or back of the projector or 
at the screen (the projector’s front sensor can detect signals bounced 
off the screen). Press the button for the function you want to use.
This chapter covers the following information:
■Controlling the picture and sound
■Using the remote control as a wireless mouse
■Replacing the remote control batteries
note
Avoid sunlight and 
fluorescent light, as these may 
interfere with signal 
reception. 
						

							44Using the Remote Control
Controlling the Picture and Sound
You can use the remote control to select your source, temporarily turn 
off the picture and sound, freeze the action, or zoom in on the picture. 
Make sure you have set up your projector and connected any 
equipment as described in Chapter 1.
Switching Between Picture Sources
If you’ve connected your projector to more than one computer and/or 
video source, you can use the buttons on the remote control to switch 
between the different sources. 
■Press the Comp1 button to select the computer or video source 
connected to the projector’s 
Computer1/Component Video1

projector’s 
Video port.
■Press the Source Search button to move successively through all 
of the input sources.
After you select a source, the screen goes dark for a moment before the

Turning Off the Picture and Sound
Press the A/V Mute button on the remote control to turn off the 
image and sound and darken your screen. This is useful if you want to 
temporarily re-direct your audience’s attention without the distraction 
of a bright screen. 
■To turn off the picture and sound, press the A/V Mute button. 
The screen goes dark.
■To turn the image and sound back on, press the button again, or 
press 
Esc.
You can create an image, such as a company logo or a picture, to 
display on the screen whenever you press the 
A/V Mute button. See 
page 63 for more information.
Stopping Action 
Press the Freeze button to stop the action in your video or computer 
image and keep the current image on the screen. The sound will 
continue, however. Also, because the source continues to transmit 
signals, you won’t resume the action from the point you paused it.
Press the 
Freeze button again or press Esc to restart it.
Zooming Your Image
Follow these steps to zoom in on a portion of the image:
1. Press the 
E-Zoombutton on the remote control. 
You see a crosshair indicating the center of the zoom-in area.
2. Use the   pointer button to position the crosshair in the area you 
want to enlarge.
3. Continue pressing the 
E-Zoombutton to enlarge the selected 
area up to 4 times.

Changing the Image’s Aspect Ratio
If you’re projecting a widescreen format image, you can use the 
Resize button on the remote control to change the aspect ratio. 
Follow these steps:
1. Press the 
Resize button once to change the aspect ratio to 16:9 
for widescreen format.
2. Press it again to return to 4:3 aspect ratio.
note
You must be projecting 
component, composite, or 
S-video images to change the 
aspect ratio. 
You can also change the 
aspect ratio using the 
projector’s Signal menu. See 
page 55 for details. 
						

							Using the Remote Control47
Using the Remote Control as a Wireless 
Mouse
When you use the remote control as a wireless mouse, you can control 
your computer or click through slideshow-style presentations (such as 
PowerPoint) from up to 20 feet away. This gives you more flexibility, 
since you don’t need to stand near your computer to change slides. 
To control your computer with the remote, make sure you have 
connected the USB cable as described on page 19. 
■To display the mouse pointer, press the Pointer button.
■To move the pointer on the screen, aim the remote at the screen 
and use the   pointer button. 
■To click (or left-click), press the Enter button.
■To right-click, press the Esc button.
■To double-click, press the Enter button twice.
■To click and drag, press down and hold the Enter button and use 
the   pointer button to move where you want to drag.
■To advance slides in a PowerPoint presentation in Slide Show 
mode, press the 
Page up or Enter button on the remote control.

							48Using the Remote Control
Replacing the Batteries
The remote control uses two AAA alkaline batteries. Follow these 
steps when you need to replace them:
1. Press in the tab to remove the battery cover.
2. Remove the old batteries, then insert the new ones as shown.
3. Replace the battery cover. (It should click into place.)
caution
When replacing batteries, 
take the following 
precautions:
■Replace the batteries as 
soon as they run out. If a 
battery leaks, wipe away 
battery fluid with a soft cloth. 
If fluid gets on your hands, 
wash them immediately.
■Do not expose batteries to 
heat or flame.
■Dispose of used batteries 
according to local regulations.
■Remove the batteries if you 
won’t be using the remote 
control for a long period of 
time. 
note
The remote control 
automatically shuts off when 
it detects a button being 
pressed more than 30 seconds. 
This conserves battery life. It 
can be helpful, for example, 
when the remote is in a 
carrying case and the 
P
Power button is 
accidentally pushed.
