Using the remote controlThe remote uses two (2) provided AAA batteries. They are easily installed 
by sliding the cover off the remote ’s back, aligning the + and - ends of the 
batteries, 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 projection screen or 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 Power button to 
place the projector in the Off state (see page 17 for shutdown info) and 
power it off.
Left and right remote mouse buttons are used to mimic the actions of the 
left/right mouse buttons on your computer. Mouse cursor movement is 
managed via the remote ’s Cursor control. Connect a USB cable to the USB 
connector on the computer and to the projector to use these buttons and 
control your computer ’s mouse. When you do this for the first time, the 
Add New Hardware wizard may appear. See page 10 for details on loading 
the correct USB drivers.
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 29 for more info on the menus.
The remote also has  Vo l u m e and Mute  buttons to control the sound, a back-
light button to light the remote ’s buttons in the dark, and  Video and Com-
puter  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 34); use the Effect button to invoke a user-defin-
able action, such as freeze, zoom or change your aspect ratio for viewing 
DVDs (see page 34 to learn to program this button).
If you are displaying presentations in Microsoft
® PowerPoint
®, you can use 
the remote ’s mouse buttons to navigate through your presentation while in 
Slide Show mode. To configure PowerPoint for this, choose  Options from 
the PowerPoint Tools menu, click the  View tab, de-select the  Popup Menu 
on Right Mouse Click  option in the Slide Show section, then click  OK. After 
that, when you ’re in PowerPoint ’s Slide Show mode, a left click advances to 
the next slide and a right click returns to the previous slide (other Power-
Point modes are not affected). 
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 screen.
 If you are trying to control your computer ’s mouse, make sure the USB 
cable is connected. If using a USB cable, make sure the correct drivers 
are installed.

Optimizing computer imagesAfter your computer is connected properly and the computer’s image is on 
the screen, you can optimize the image using the onscreen menus. For gen-
eral information on using the menus, see page 29.
Adjust the Keystone, Contrast, or Brightness in the Picture menu 
(page 30). 
Change the Aspect Ratio. Choose the option that best fits your input 
source (page 30).
Adjust the Color Temperature in the Advanced menu (page 32).
Adjust the phase, Tracking, or Horizontal or Vertical position in the 
Advanced menu (page 32).
Once you have optimized the image for a particular source, you can 
save the settings using Presets. This allows you to quickly recall these 
settings later (page 31).
Presentation featuresSeveral features are provided to make giving presentations easier. Here is an 
overview, details are found in the menu section.
The Effect button on the remote allows you to assign various features to 
the button. The default effect is About, which displays information 
about the projector and current source. You can select among Blank, 
Mute, Aspect Ratio, Source, Auto Image, Freeze, Zoom, and About. See 
page 34 for details. The freeze effect allows you to freeze the displayed 
image. This is useful if you want to make changes on your computer 
without your audience seeing them. The mask effect allows you to 
cover part of the image with a black curtain.
The Blank button on the remote allows you to display a blank screen 
instead of the active source. You can determine the color of this screen 
(page 34).
The Startup Logo option lets you change the default start up screen to a 
blank or default screen (page 34).
Two options, Power Save and Screen Save, are provided to automati-
cally shut down the projector after several minutes of inactivity or dis-
play a black screen. This helps preserve lamp life (page 33).

Using the menusTo open the menus, press the Menu button on the keypad or remote. (The 
menus automatically close after 60 seconds if no buttons are pressed.) The 
Main menu appears. Use the arrow buttons to move up and down to high-
light the desired submenu, then press the Select button. 
To change a menu setting, highlight it, press Select, then use the up and 
down arrow buttons to adjust the value, select an option using radio but-
tons, or turn the feature on or off using check boxes. Press Select to confirm 
your changes. Use the arrows to navigate to another setting. When your 
adjustments are complete, navigate to Exit, then press Select to go to the 
previous menu; press the Menu button at any time to close the menus. 
Dots appears before the menu name. The number of dots indicate menu’s 
level, ranging from one (the Main menu) to four (the most nested menus). 
The menus are grouped by usage:
The Picture menu provides image adjustments.
The Settings menu provides set-up type adjustments that are not 
changed often.
The About menu provides a read-only display of information about the 
projector and source. 
Certain menu items may not be visible or may be grayed depending upon a 
particular source being connected. For example, Sharpness is only available 
for video sources and is not visible when a computer source is active. Menu 
options are grayed out only if the source if selected but no signal is present. 
For example, if the projector is set to a video source but the source, such as a 
DVD player, is turned off video menu options are grayed out.
