Using the Remote Control
The projector includes a number of tools to enhance your 
presentation. All of them can be accessed using the remote control, 
which lets you operate the projector from anywhere in the room—up 
to 30 feet away. 
You can use the remote control to adjust the picture and sound 
(page 35), or as a pointer or drawing tool to highlight your 
presentation (page 41). You can also use it to make automatic color 
corrections that let you project images onto any surface (page 43), or 
as a wireless mouse when projecting from a computer (page 44). 
Finally, you can use it to prevent unauthorized use of your projector 
by assigning the projector a password.
This chapter covers:
■Activating and using the remote control
■Controlling the picture and sound
■Highlighting your presentation
■Projecting images without a screen
■Operating your computer with the remote control
■Enabling password protection

							32Using the Remote Control
Activating and Using the Remote 
Control
The remote control has an ON/OFF switch on its side, as shown. 
Before using the remote, make sure batteries are installed as described 
on page 34, then push up on the 
ON/OFF switch to turn it on. 
Turn off the remote control before transporting or storing it; this 
prevents the batteries from discharging if something presses against 
one of the buttons. 
Here are some additional tips:
■Point the remote control either at the front or back of the 
projector, or at the screen.
■Stand within 30 feet of the projector. If you want to operate the 
projector from a greater distance, a remote control cable set is 
available (see page 14).
■When presenting in a darkened room, press the  light button to 
make the buttons on the remote light up temporarily. 
■Avoid using the remote under bright fluorescent lamps or in 
direct sunlight, or the projector may not respond properly.

note
If a button is pressed longer 
than 60 seconds, the remote 
control stops operating to 
conserve power. When you 
release the button, normal 
operation resumes.  
						

							Using the Remote Control33
Using the Navigation Buttons
The remote control has various buttons that let you navigate the 
projector’s help and menu systems; they also let you use the drawing 
tools to highlight your presentation. If you’ve connected a computer, 
the buttons can be used in place of your computer’s mouse, letting 
you walk about freely while controlling your presentation.
For details on using the buttons to control specific features, see the 
following sections: 
■to highlight your presentation, see page 41
■to use the remote control in place of your computer’s mouse, 
see page 44
■to navigate the projector’s menu system, see page 124
■to create your own startup screen, see page 132
■to use the remote to control more than one projector, see 
page 135

Replacing the Batteries 
If the projector stops responding to the remote control, check the 
following:
■Make sure the remote control’s ON/OFF switch (shown on 
page 32) is in the 
ON position. 
■Press the  light button and check to see if the buttons on the 
remote control light up. (If you’re in a bright room, you may not 
be able to see them light.)
If the buttons do not light up, replace the batteries as described below: 
1. Turn the remote control over. 
2. Press down on the ridges at one 
end of the battery cover as you 
slide the cover off.
3. Install two AA batteries, inserting 
the flat (negative) ends in first.
4. Slide the cover back in place.
caution
When replacing batteries, 
take the following 
precautions:
■Replace the batteries as 
soon as they run out. If the 
batteries leak, wipe away 
battery fluid with a soft 
cloth. If fluid gets on your 
hands, wash 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 
projector for a long period of 
time.

Controlling the Picture and Sound
You can use the remote control to preview and select your picture 
sources, temporarily turn off the picture and sound, freeze the action, 
zoom in on the picture, display a picture-in-picture image, and adjust 
the volume. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can switch between the different sources: 
■On the projector’s control panel, there are two Source buttons: 
Press the 
Computer/DVI button to switch between EasyMP and 
equipment connected to the 
Computer and DVI ports. Or press 
the 
Video/BNC button to switch between equipment connected 
to the 
Video, S-Video, and BNC ports. 
■On the remote control, there are six Source buttons. Use them to 
switch between equipment connected to the port identified on 
each button, or to use EasyMP to project wirelessly or from a 
memory card.
Note that the 
Computer and BNC ports can be set up to use different 
input signals (for example, Analog RGB or RGB Video)—so if you 
have equipment connected to one of these ports, it’s important to 
make sure the correct signal is selected to match the equipment you’re 
using. You can change the input signal settings using the projector’s 
menu system; see page 137. 
After you select a source, the screen goes dark for a moment before the 
image appears.
note
You can use the projector’s 
menus to fine-tune the 
picture and sound quality as 
described in Chapter 4.

the preview window for that source appears blank. 
2. Press one of the 
Source buttons on the remote control to switch 
to the desired source, and press 
Enter to change the source and 
exit the screen. Or press

							38Using the Remote Control
Turning Off the Picture and Sound 
You can use the A/V Mute button on the remote control to turn off 
the image and sound and darken your screen. (If you’ve connected a 
computer to the projector’s 
Computer port and an external monitor 
to the projector’s 
Monitor Out port, the monitor will continue 
displaying.) This feature is useful if you want to temporarily redirect 
your audience’s attention without the distraction of a bright screen. 
■To turn off the picture, press the A/V Mute button. The screen 
goes dark. 
■To turn the image back on, press the button again.
You can also have an image, such as a company logo, display on the 
screen whenever you press the 
A/V Mute button (see page 132).

You can use the remote control to stop the action in your video or 
computer image. 
■Press the Freeze button to stop the action and keep the current 
image on the screen. The sound continues. 
■Press the Freeze button again to restart it.
note
This function pauses the 
image, but not the sound. 
Also, because the source 
continues to transmit 
signals, you won’t resume 
the action from the point 
you paused it.
