Garmin 74C 用户手册

Depending on your presentation, you can take advantage of any or all 
of these options:

■

Connecting to a laptop or other computer

If you want to connect the projector to a laptop or desktop 
computer, see page 16. For additional presentation control, you 
can connect the USB cable to the projector for running slide 
shows, and connect an external monitor to view the presentation 
on your computer simultaneously.

■

Connecting to video sources

You can connect a DVD player, VCR, HDTV, camcorder, laser 
disc player, digital camera, and other video sources to your 
projector. See page 22 for instructions.

■

Using the remote control

The remote control lets you switch from computer to video 
sources, zoom in on part of your image, freeze or mute the 
presentation, and adjust many other projector features. For 
details, see Chapter 3.

By connecting an additional cable, you can also use the remote 
control as a wireless mouse. This lets you click through 
computer-based presentations (such as PowerPoint

®

) from up to 

20 feet away. For more information, see page 43. 

■

Including sound in your presentation

If your presentation includes sound, you can connect an optional 
audio cable to use the projector’s built-in speaker. See page 20.
