BTurn off the power supply for all components before making any connections. BIf 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. BIf 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). BThe projector has a built-in speaker. 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 speaker while the AUDIO OUT jack is being used. BIt may not be possible to connect some types of computer.

Correcting keystone distortionKeystone distortion is corrected automatically when the projector’s automatic setup function is used, but this correction will not apply if the screen itself is tilted. In such cases, you can correct the keystone distortion manually with the following procedure. #Select “KEYSTONE” from the MAIN MENU screen, and then press the ENTER button. $Press the I I or H H buttons to correct the keystone distortion. Picture condition Operation Press the H H button. Press the I I button.%Press the MENU button to return to the previous screen. NOTE: BIf you press the AUTO SETUP button after correcting the keystone distortion manually, the automatic keystone correction function will operate and the corrected picture will return to its previous incorrect condition. To prevent this from happening, you can set “AUTO KEYSTN” in the OPTION1 menu to “OFF”. BKeystone distortion can be corrected to ±30° of the angle of tilt for the projector. However, the greater the correction amount, the more the picture quality will deteriorate, and the harder it will become to achieve a good level of focus. To obtain the best picture quality, set up the projector and screen in such a way that the amount of keystone correction required is as minimal as possible. BThe picture size will also change when correction of keystone distortion is carried out. %Use the D.ZOOM +/- buttons to change the enlargement ratio. The enlargement ratio can be changed within the range of x1 to x2, in steps of 0.1. NOTE: BWhen RGB signals are being input, the enlargement ratio can be changed within the range of x1 to x3.

39 Basic Operation 38 S4:3 The size of the input signal is compressed to 75% and projected. (This is useful for projecting a picture with a 4:3 aspect ratio onto a 16:9 screen.) AUTO (S-VIDEO only) When an S1 video signal is input to the S-VIDEO terminal, the aspect ratio is changed automatically to project a 16:9 picture. 4:3 The input signal is projected without change. 16:9 The picture is compressed to a ratio of 16:9 and projected. ASPECTThis setting is only for an S-VIDEO/ VIDEO signal and a YP BPRsignal in 525i (480i), 525p (480p) and 625i format. ASPECT AUTO [ 4:3 [ 16:9 [ S4:3 NOTE: B This projector is equipped with an aspect ratio selection function. However, if a mode which does not match the aspect ratio of the input signal is selected, it may affect the quality of viewing of the original picture. Keep this in mind when selecting the aspect ratio. B If using this projector in places such as cafes or hotels with the aim of displaying programs for viewing for a commercial purpose or for public presentation, note that if the aspect ratio (16:9) selection function is used to change the aspect ratio of the screen picture, you may be infringing the rights of the original copyright owner for that program under copyright protection laws. B If a normal (4:3) picture which was not originally intended for wide- screen viewing is projected onto a wide screen, distortion may occur around the edges of the picture so that part of the picture is no longer visible. Such programs should be viewed in 4:3 mode to give proper consideration to the aims and intentions of the original program’s creator. S1 video signals B S1 video signals are a type of video signal with an aspect ratio of 16:9 which include a detector signal. This detector signal is output by some sources such as wide-vision video decks. If the AUTO setting above is selected, this projector will recognise the detector signal and automatically switch the aspect ratio to 16:9 in order to project the picture. RESIZINGThis should normally be set to “ON”. (This setting is only for signals which have lower resolutions than the LCD panels. Refer to page 56 for details.) ON The pixel resolution of the input signal is converted to the same resolution as the LCD panels before being projected. For signals with lower resolutions, gaps in the pixels are automatically interpolated into the picture before it is projected. This may sometimes cause problems with the quality of the picture. OFF The picture signal is projected at its original resolution, with no pixel conversion. The projected picture will be smaller than normal, so adjust the zoom setting or move the projector forwards or backwards to adjust the picture size if necessary. If set to “OFF”, some features, such as D.ZOOM (digital zoom), keystone distortion correction or INDEX WINDOW will not function. When a squeezed signal is being input.
