Adjusting the Volume
You can use the buttons on the remote control or projector to increase 
or decrease the volume for both the projector’s built-in speaker and 
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; otherwise you may 
not be able to see your computer’s display to shut it down 
properly.
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.
Volume controls
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 of
f 
through the Extended menu. 
See page 59. 
						

							42Projecting3. Press the P 
Power button again. The projector beeps twice, the 
lamp is turned off, and the power light flashes orange for about 60 
seconds as the projector cools down. When the projector has 
cooled, the 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.
7. If you won’t be using the projector for awhile, store it in the soft 
case that came with it or in a protective case.
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

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.

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.

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.

							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

							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.
