31 Operations CONTENTS Notes •To change the projecting angle, adjust the foot adjuster. 21 •If the screen image suffers keystone distortion, press the KEYSTONE button to adjust the distortion. 34 •Due to lamp characteristics, flickers may occasionally occur in a picture. This is not malfunction of the unit. •The lamp may rarely burst with a loud sound. •The projector’s liquid crystal panel is made using extremely advanced technology, but there may be black spots (pixels that do not light) or bright spots (pixels that are constantly lit) on the panel. Please note that these are not malfunctions. •When trying to press a button whose operation is not available, the icon appears. •When supplying the signal not compatible with the projector, the icon appears. •When signals are not input from the input source, the icon appears. •The projector may stop operating if the surrounding temperature is too high or if the air filter is clogged with dust. 60 Press VOL/ADJ (+/-) to adjust volume. Press the (+) button to increase volume. Press the ( -) button to decrease volume. 8 VOL/ADJ VOL/ADJ Projection on the screen (continued) MENU ON /INPUT ENTER CT-90106 KEYSTONE AUTO SET EXIT / P.MODE PIP FREEZE MUTE CALLRESIZE VOL / ADJ STANDBY KEYSTONE AUTOSET EXIT ON / STANDBY VOL / ADJ ENTER MENU INPUT FANTEMPLAMPON 8 8 Remote control Control panel (Main unit side) About the LCD Panel The life of the LCD panel is limited. Take care over the points below so as to use the panel for years. •To prolong the life of this panel, never fail to turn the power off when the panel is not in use and make sure that the lamp has gone out. The state of the lamp being extinguished helps enhance the effect of energy saving. •If the air filter is stained and is clogged up, the main unit inner temperature rises. As a result, the life of the LCD is shortened and a malfunction may also occur. Clean the air filter from time to time 61 and replace it regularly. It is recommended that this replacement be done at the time of replacing a lamp. (Ask a dealer where the unit was purchased or your nearby service station about an air filter for replacement.)
32 Operations CONTENTSTurning the power off Press ON/STANDBY after using the projector. An instruction message for turning the power off appears on the screen and disappears after a while. When the message disappears, operation becomes invalid. Press ON/STANDBY again. Cooling starts. Once cooling is completed, the LAMP and FAN indicators turn off and the standby mode is set. (The ON indicator turns in orange.) To protect the light source lamp, the LAMP indicator blinks as long as a minimum of cooling is necessary. The power cannot be turned back on during this time. Unplugging the power cord at this time will shorten the lamp’s duration life. The cooling fan continues to run for a while to expel the heat remaining inside. If you are in a hurry, however, you may unplug the power cord at this time. The standby mode is set. 1 2 MENU ON /INPUT ENTER CT-90106 KEYSTONE AUTO SET EXIT / P.MODE PIP FREEZE MUTE CALLRESIZE VOL / ADJ STANDBY 2 1,21,2 KEYSTONE AUTOSET EXIT ON / STANDBY VOL / ADJ ENTER MENU INPUT FANTEMPLAMPON (Green) (Green) (Green) (Off) (Off) (Off) Flashing(Orange) (Orange) ABC ONLAMP FA N ONLAMP FA N ONLAMP FA N(Orange) ON/STANDBY ON/STANDBY ON/STANDBY ON/STANDBY B C A Notes •The projector consumes about 15W of power in the standby mode. We recommend you unplug the power cord when not using the projector for long periods of time. •Be sure that the LAMP indicator has turned off before unplugging the power cord. Cutting the power by unplugging the power cord while the projector is operating or the light source lamp is being cooled will shorten the lamp’s duration life. Should a fault or some other irregularity arise with this unit, unplug the power cord. •When reinserting the power plug before the lamp has cooled, please wait until the lamp has cooled sufficiently before use. When the lamp is at a high temperature, it may not light and it’s life duration will be shortened. Remote control Control panel (Main unit side) Indicators
33 Operations CONTENTS Notes •Automatic adjustment may not be performed properly for signals other than those computers’ signals with which the projector is compatible. •The horizontal position, vertical position, sampling phase and sampling frequency can also be adjusted from the menu screen 46. * Sampling frequency Analog RGB signals input from the computer are converted into digital signals inside the projector. The sampling frequency is the number of times per second the analog signals are converted into digital signals. In order to capture (sample) each individual dot of the computer’s signals, the sampling frequency must be adjusted to match the computer’s dot clock frequency. If this adjustment is off, details of the image details may be blurred, a striped pattern may appear if images with many vertical lines are displayed, or the image’s width may change. For computer signals with which are projector-compatible, the sampling frequency is adjusted automatically even when the AUTO SET button is not pressed. * Sampling phase The sampling phase is the timing at which the computer’s analog RGB signals are sampled. If the sampling phase is off, the individual dots cannot be sampled at the proper timing, resulting in blurred or flickering images.
