Preparing the Projector This chapter explains how to install the projector and connect projection sources..
Installation Methods The projector supports the following four different projection methods. Install the projector according to the co nditions of the installation location. • Project images from in front of the screen. (Front projection) • Project images from behind a translucent screen.
• Install the projector so that it is parallel to the screen. If the projector is installed at an angle to the screen, keystone distortion occurs in the projected image. • Place the projector on a level surface. If the projector is tilted the projected image is also tilted.
The port name , location, and connector orientation differ depending on the sour ce being connected. Connecting a Computer To project images from a computer, connect th e computer using one of the following methods. A When using the suppli ed computer cable Connect the computer's display output port to the projector's Co mputer port.
Connecting a Smartphone or Tablet Device You can connect smartphones and tablet devices. By using a comme r c i a l l y a v a i l a b l e M H L c a b l e , y o u c a n c o n n e c t t h e M H L p o r t o n y o ur device to the HDMI/MHL port on the projector.
Connecting Image Sources To project images from DVD players or VHS video and so on, connect to the projector using one of the following methods. A When using a commercially available video or S-video cable Connect the video output port on the image source to the projec tor's Video port.
Attention • Turn off the equipment you want to connect before connecting. If the input source is on when you connect it to the projector, i t could cause a malfunction. • If the orientation or shape of the plug differs, do not try to force it in .
Attention • I f y o u u s e a U S B h u b , t h e c o n n e c t i o n m a y n o t o p e r a t e c o r r e c t l y . D e vices such as digital cameras and USB devices should be conne cted to the projector directly. • When connecting and using a USB-compatib le hard disk, make su re you connect the AC adaptor supplied with the hard disk.
Installing the Wireless LAN Unit By installing th e supplied or optional wireless LAN unit, you can project the computer screen that is connected to the wireless LAN over a network.
a If the Wireless LAN unit is installed on the projector, press the [LAN] button on the remote control. The LAN standby screen is displayed. b Check that the SSID and IP address information are displa yed on the LAN standby screen, and then remove the Wireless LAN unit.
