Epson PowerLite 713c Benutzerhandbuch

The projector can be installed for three different viewing setups: front 
projection, ceiling mounting, or rear projection onto a 
semi-transparent screen.

To project from overhead, you’ll need to select 

Ceiling

 in the 

projector’s Advanced menu. To project from the rear, select 

Rear 

Proj

. See page 48 for more information.

If you’re ceiling-mounting the projector and you place it above screen 
level, you’ll have to tilt it down to position the image on-screen. This 
causes the image to lose its rectangular shape. You can then correct the 
distortion by using the 

Keystone

 function in the projector’s menu 

system (see page 46).

If you place the projector’s lens so it’s level with the top of the screen, 
the image will be rectangular and you won’t have to adjust it. If you 
place the lens lower than the top of the screen, you’ll have to tilt the 
projector upward if you want to fill the whole screen with the image. 

The projector’s internal speaker is loud enough for most rooms. 
However, if your installation requires maximum volume and sound 
quality, you can connect the projector to external speakers or a public 
address (PA) system. If you’ve connected a computer and video 
source, the projector will automatically switch the audio whenever you 
switch sources (see page 30).

To connect the projector to an external sound system, you will need 
an RCA-to-3.5 mm stereo audio cable, which may be included with 
your sound system, or may be purchased from an electronics store.
