Using the remote control
The remote uses two (2) provided AA batteries. They are easily installed by 
removing the cover from 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 
environmentally proper manner.
To operate, point the remote at the front of the projector (not at the 
computer). The range of optimum operation is about 15 feet (4.5m).
Press the remote’s Power button to turn the projector on and off (see page 14 for shutdown info).
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 27 for more info on the menus.
The remote also has a Source button to switch between sources.
The remote also has:
•Volume buttons to adjust the sound.
•Custom button that can be assigned to a special function, like Blank 
Screen or Freeze (see 
page 30).
•Source button to switch between sources.
•Blank button to blank the screen.
•Presets button to select stored settings (see page 28).
•Mute button to silence the audio.
•Auto Image button to resynch the projector to the source
•Resize button to switch among aspect ratios (see page 28).
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.

Using the audio
Using the projector’s speakers
When the computer is using the DisplayLink connector, both audio and 
video are sent over the USB cable to the projector and audio will play from 
the projectors speakers.
For inputs other than DisplayLink, to use the projectors speakers, connect 
the audio source to the Audio In Computer or Video connectors.
To adjust the volume, press the Volume buttons on the keypad or remote.
Troubleshooting Audio
If you aren’t hearing the audio, check the following:
• If your computer is using the projectors DisplayLink connector, see the 
InFocus DisplayLink Manager Users Guide for audio troubleshooting 
information
• Make sure the audio cable is connected to the correct Audio In 
connector, Computer or Video.
• Make sure the volume is turned up enough. Press the Volume 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 speakers
The 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.
