Using the remote control
The remote uses two (2) provided AA batteries. You can install the batteries 
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.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Ensure the batteries’ polarity (+/-) is aligned correctly.
• Do not mix new and old batteries together, or different types of 
batteries together.
• Replace the batteries as soon as they run out.
• Remove batteries from the remote control when storing or not in use 
for a prolonged period.
To operate, point the remote at the projector (not at the computer). The 
range of optimum operation is about 30’ (9m).
Press the remote’s Power button to turn the projector on and off (see page 14 for shutdown information).
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 26 for more information on the menus.
The remote also has:
•Help button to access the projector’s help feature (see page 32).
•Volume buttons to adjust the sound.
•Custom button that can be assigned to a special function, like Blank 
Screen or Freeze (see 
page 29).
•Source button to switch between sources.

•Presets button to select stored settings (see page 27).
•Mute button to silence the audio.

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 30’ (9m). For best 
results, point the remote at the projector.

Using the audio
Using the projector’s speakers
When the computer is using the DisplayLink or HDMI connectors, both 
audio and video are sent over the respective cable to the projector and audio 
will play from the projectors speakers.
For inputs other than DisplayLink and HDMI, connect the audio source to 
the associated audio connectors in order to use the projectors speakers.
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 Software Users Guide on the website at 
www.infocus.com/displaylink 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 you are connected to the corresponding audio in for your 
source. 
• 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. 
NOTE: DisplayLink and HDMI audio is passed to the Audio Out connector.
