Furthermore, the remote control unit can be operated from an angle of ±30 ° to the left or right and ±15 ° above or below the receptors. NOTE: • If there are any obstacles in between the remote control unit and the receptors, the remote control unit may not operate correctly. • If strong light is allowed to shine onto the remote control signal receptor, correct remote control operation may not be possible. Place the projector as far away from light sources as possible. • If facing the remote control unit toward the screen to operate the projector, the operating range of the remote control unit will be limited by the amount of light reflection loss caused by the characteristics of the screen used. w Connections Notes on connections • Read the instruction manual for each system component carefully before connecting it. • Turn off the power supply for all components before making any connections. • If the cables necessary for connecting a component to the system are not included with the component or available as an option, you may need to fashion a cable to suit the component concerned. • If there is a lot of jitter in the video signal which is input from the video source, the picture on the screen may flicker. In such cases, it will be necessary to connect a TBC (time base corrector). • The projector has built-in speakers. However, you will need to connect a separate audio system to the AUDIO OUT jack if your needs specify high sound volumes. No sound will come out of the projector’s built-in speakers while the AUDIO OUT jack is being used. • It may not be possible to connect some types of computer. Refer to the list of compatible signals on page 50. • The pin layout and signal names for the S-VIDEO IN connector are shown below.

Select whichever projection method matches the settingup method. (The projection method can be set from the Option menu. Refer to page 37 for details.)
