E – 35Select either the RGB signal type or the Component signal type.RGB ............. RGB signalComponent .. Composite signals such as YCbCr/YPbPrNOTE: This feature is available on RGB 1 and 2 only.Switcher GainThis feature adjusts the input level of the signal. This must be doneto each color:R, G, and B.VolumeThis feature adjusts the volume of the audio output. Adjust the soundcorresponding to the slot.Ref AdjKeystoneThis feature corrects the keystone (trapezoidal) distortion to make thetop of the screen longer or shorter to be the same as the bottom.Use the or buttons on the slide bar to correct the keystone (trap-ezoidal) distortion.Keystone distortion NormalNOTE:1) With the projector aimed directly at the screen the maximum keystone anglethat can be corrected is +/- 7.5 degrees.2) When "Resolution" is set to "Native", this feature is not available, and the storedsettings and adjustments are invalid.Depending on the type of graphics being used, the picture may get blurred orkeystone correction may not be possible when excessive keystone correctionis used.The idea is, the closer you are to native resolution, the better image you willsee.NOTE: The keystone feature is not available when the test pattern or the blueback is displayed.Switcher (available only when used with ISS-6020)Signal TypeThis function serves to store the adjusted value when using the Shift,Focus, and Zoom buttons of the main unit or the remote control.Usage ExampleWhen you wish to display on a screen having a 4:3 aspect ratio anNTSC or other 4:3 aspect ratio signal and an SXGA or other 5:4 aspectratio signal:Perform shift, focus, and zoom adjustments to set the vertical screensize of the vertically long 5:4 aspect ratio signal to standard.Both 4:3 apsect ratio signals and 5:4 aspect ratio signals can now bedisplayed.Note that with these shift, focus, and zoom adjustments, the 4:3 aspectratio signal will become smaller on the screen.To eliminate this size reduction, adjust the shift, focus and zoom to theoptimum condition for each of the 4:3 aspect ratio signal and the 5:4aspect ratio signal. Memory (storage) of each of these values will per-mit projection at an optimum condition upon signal switching.1) Select "Projector Options" → "Setup" → "Page 4" → "Lens Memory" andthen insert a check mark into the Lens Memory check box.2) Set to no-signal condition or project a 5:4 aspect ratio signal and thenadjust each of shift, focus, and zoom.3) Select "Reference" under "Adjust(Source)" → "Lens Memory" → "Refer-ence/Custom" and store your adjustments.* For signals other than those having a 5:4 aspect ratio (or, 5:4 aspect ratiosignals that you wish to adjust separately), adjust shift, focus, and zoom,select "Custom" under "Reference/Custom", then press "Store".The differences between "Reference" and "Custom" are described below."Reference": Valid adjustment value for a no-signal condition and anewly input signal "Custom": Custom adjustment value for a specificsignalNote that when "Reference" is stored, it will be overwritten since it isnot an adjustment that changes with each signal.In the aforementioned description, signals having a 5:4 aspect ratioare restricted to "Reference", but signals having other aspect ratioscan also be used as standard signals.Another method to store values is to press the INFO button whileholding down the CTL button of the remote control.Note that when using the remote control for storing, storage will bein "Reference" when the "Lens Memory" setting of the menu is "Ref-erence", and storage will be in "Custom" when the setting is "Cus-tom". Defaults such as newlyinput signals are "Reference".Lens Memory
