Setting Up the Projector
4. If necessary, configure your laptop to work with an external 
mouse. 
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 18 for instructions.
Amplifying Computer Audio
Your laptop probably has its own sound system; however, it may not 
be adequate for your presentation. If you need more volume or better 
sound quality, you can connect a computer audio cable to take 
advantage of the projector’s built-in amplifier and speaker. You can 
obtain a computer audio cable (3.5-mm stereo miniplug cable) from a 
computer or electronics dealer.
1. Connect one end of the audio cable to the 
Audio In 
jack on the 
projector.
  
2. Connect the other end of the audio cable to your laptop’s  
headphone jack or 
 audio-out jack. (Jack locations vary; see 
your computer manual if you’re not sure which jack to use.)
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 18 for instructions.
