Garmin 74C Manual De Usuario

Your computer probably has its own sound system; however, it may 
not be adequate for your presentation. If you need more volume, 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 

Audio1 

jack on the 

projector.

2. Connect the other end of the audio cable to your laptop’s

 headphone jack or 

 audio-out jack, or your desktop’s 

speaker or audio-out port.

3. After you turn on your projector, open the Audio menu and make 

sure 

Audio 1

 is selected for the 

Audio Input

 setting. See page 51. 

If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 28 for instructions.
