Garmin 74C 用户手册

Selecting the image source lets you switch between images input from 
different pieces of equipment connected to the projector (such as a 
computer and DVD player). If you don’t see the image you want, 
select it as follows:

■

On the projector, press the 

Source

 button until the correct 

device image is projected. 

■

On the remote control, press the 

Computer1/2

 button to select 

the device connected to the Computer1/Component Video1 or 
Computer2/Component Video2 port. For the S-Video or Video 
port device, press the

 S-Video/Video

 button.

If a projected image fails to appear, see the next section for help. 

Once you see your image, turn to page 33 for instructions on focusing 
and making other image adjustments. 

If you see a blank screen or a blue screen with the message 

No Signal 

after turning on your computer or video source, try the following:

■

Make sure the cables are connected correctly, as described in 
Chapter 1.

■

Make sure the power light is green and not flashing and the lens 
cap is off. 

■

Press the 

Source

 button on top of the projector to select the 

correct source. (Allow a few seconds for the projector to sync up 
after pressing the button.) 

■

Check the 

Input Signal

 setting in the Image menu to make sure 

it matches the port to which the device is connected. See page 50.
