Additional Information English Additional Information Precautions regarding use Panel sticking and after-image lag • Displaying the same images such as still images for a long time may cause after-image lagging. This may occur in the following two cases. 1. After-image lagging due to remaining electrical load When image patterns with very high peak luminance are displayed for more than 1 minute, after-image lagging may occur due to the remaining electric load. The after-images remaining on the screen will disappear when moving images are displayed. The time for the after-images to disappear depends on the luminance of the still images and the time they had been displayed. 2. After-image (lag image) due to burning Avoid displaying the same image on the Plasma Display continuously over a long period of time. If the same image is displayed continuously for several hours, or for shorter periods of time over several days, a permanent after-image may remain on the screen due to burning of the fluorescent materials. Such images may become less noticeable if moving images are later displayed, but they will not disappear completely. The same kind of burning of a lag image may also be produced after extended multi-hour use, or recurrent daily use for shorter periods of a single [4:3] screen size, or [DOT BY DOT] image. Except in cases where violation of intellectual property rights may be involved (pages 20 and 21), it is recommended that lagimage burning be avoided by selecting a screen size that displays images over the entire screen (page 20). • In addition, the [ORBITER] function (page 28) and [ENERGY SAVE] function (page 30) can also be used to reduce the chance of lag image formation. Note Special precautions must be employed when using the Plasma Display as a surveillance monitor or in other applications where a fixed image will be displayed for extended periods of time. Before using the monitor in such applications, consult your dealer for advice. When using this unit as a monitor for a surveillance camera, it is recommended to set the [ENERGY SAVE] function to [MODE3] or [MODE2]. About the plasma panel's protection function The brightness of this display will deteriorate slightly when an image with little movement such as a photograph or computer image is continuously displayed. This is caused by the plasma panel's protection function which detects images with slight movement and automatically adjusts brightness to protect the display, and is not a malfunction. The screen-saver function begins operating when the display detects no or little screen movement for a period of about three minutes; the function is an automatic feature and cannot be turned OFF. Pixel failure The Plasma Display screen is composed of a high numbers of tiny pixel elements constructed in a high-precision array, but on occasion one or more of the pixels may fail to light, or may light erratically. This is an inevitable by-product of the manufacturing process and not a malfunction. 38 En Concerning infrared light In principle, the Plasma Display radiates infrared light. Depending on the environment in which the monitor is installed and used, infrared remote control units for other nearby appliances may fail to operate properly, or noise may be heard in wireless headphones. In such cases, move the affected appliance to a location where its infrared sensor is not affected. Electromagnetic interferrence This unit is built in compliance with official standards for eletromagnetic interference, but it nonetheless may produce a low level of radio noise. This noise may be noticeable if AM radios, computers, or video appliances are installed too close to the display. In such cases, remove the affected appliance to a location where it is not affected. Drive Noise When power is turned on, some degree of drive noise may be heard; this is normal and not a malfunction. Plasma Display Temperature When the display is used for long periods of time, some parts of the display may retain heat and the display may become hot to the touch; this is normal and not a malfunction. Additional cautions • If the power is automatically turned off during operation of this unit, the following reasons may be the cause. 1 Is the [POWER MGT.] function set to [ON]? (page 23). 2 The surrounding temperature has risen above 40 °C. The display should be used within ambient temperature conditions below 40 °C. 3 The internal temperature has risen abnormally due to blocked cooling vents, overheating of internal electronic parts, or other factors. If the power is automatically turned off for a reason other than the above reasons, there could be a malfunction. In this case, unplug the power cord from the power outlet and request repair from your nearest sales outlet. • The Plasma Display panel of this unit is very bright and viewing it a close distance will cause eye strain. We recommend that you view the screen from a suitable distance (3 to 6 m). • In order to protect the panel and internal circuitry, this display is provided with a cooling fan designed to turn on/off and change speed automatically in accordance with ambient temperature conditions (the fan sound will change in accordance with its speed). The display should be used within ambient temperature conditions below 40 °C. STANDBY/ON indicator During operation of the [POWER MGT.] function, this indicator will flash green at intervals of about 1 second (page 23). This indicator lights steadily (green) under nomal operating conditions. However, depending on the settings performed by the installation technician, the green indicator may not light even when power is turned on (page 37). If the green light displays a flashing pattern other than the above, an error message is indicated. Consult any onscreen messages (page 36) and check ambient conditions (temperature, etc.) and respond accordingly (page 37). If the problem persists, disconnect the power plug and consult your dealer or a service center. Other than this, if the power turns off by itself, or refuses to turn on, or if this indicator conditions flashing red, a malfunction may be indicated. Immediately disconnect the power plug and consult your dealer or a service center.
