En-2PrecautionsPlease read this manual carefully before using your plasma monitor andkeep the manual handy for future reference.CAUTIONRISK OF ELECTRIC SHOCKDO NOT OPENCAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DONOT REMOVE COVER. NO USER-SERVICEABLEPARTS INSIDE.REFER SERVICING TO QUALIFIED SERVICEPERSONNEL.This symbol warns the user that uninsulated voltagewithin the unit may have sufficient magnitude to causeelectric shock. Therefore, it is dangerous to make anykind of contact with any part inside of this unit.This symbol alerts the user that important literatureconcerning the operation and maintenance of this unithas been included.Therefore, it should be read carefully in order to avoidany problems.WARNINGTO PREVENT FIRE OR SHOCK HAZARDS, DO NOT EXPOSE THISUNIT TO RAIN OR MOISTURE. ALSO DO NOT USE THIS UNIT’SPOLARIZED PLUG WITH AN EXTENSION CORD RECEPTACLE OROTHER OUTLETS, UNLESS THE PRONGS CAN BE FULLYINSERTED. REFRAIN FROM OPENING THE CABINET AS THEREARE HIGH-VOLTAGE COMPONENTS INSIDE. REFER SERVICINGTO QUALIFIED SERVICE PERSONNEL.Warnings and Safety PrecautionThis plasma monitor is designed and manufactured to providelong, trouble-free service. No maintenance other than cleaningis required. Please see the section “Plasma monitor cleaningprocedure”.The plasma display panel consists of fine pictureelements (cells) with more than 99.99 percent active cells. Theremay be some cells that do not produce light or remain lit.For operating safety and to avoid damage to the unit, readcarefully and observe the following instructions.To avoid shock and fire hazards:1. Provide adequate space for ventilation to avoid internal heat build-up. Do not cover rear vents or install the unit in a closed cabinet orshelves.If you install the unit in an enclosure, make sure there is adequatespace at the top of the unit to allow hot air to rise and escape. If themonitor becomes too hot, the overheat protector will be activated andthe monitor will be turned off. If this happens, turn off the power to themonitor and unplug the power cord. If the room where the monitor isinstalled is particularly hot, move the monitor to a cooler location, andwait for 60 minutes to cool the monitor. If the problem persists, contactyour dealer for service.2. Do not use this unit’s polarized plug with extension cords or outletsunless the prongs can be completely inserted.3. Do not expose the unit to water or moisture.4. Avoid damage to the power cord, and do not attempt to modify thepower cord.5. Unplug the power cord during electrical storms or if the unit willnot be used over a long period.6. Do not open the cabinet which has potentially dangerous high voltagecomponents inside. If the unit is damaged in this way the warranty willbe void. Moreover, there is a serious risk of electric shock.7. Do not attempt to service or repair the unit. The manufacturer is notliable for any bodily harm or damage caused if unqualified personsattempt service or open the back cover. Refer all service to authorizedService Centers.8. This equipment shall be connected to a MAIN outlet with a protectiveearth-ground connection.9. The outlet shall be installed near the equipment and shall be easilyaccessible.To avoid damage and prolong operating life:1. Use only with 100-240V 50/60Hz AC power supply. Continuedoperation at line voltages greater than 100-240 Volts AC will shortenthe life of the unit, and might even cause a fire hazard.2. Handle the unit carefully when installing it and do not drop.3. Set the unit away from heat, excessive dust, and direct sunlight.4. Protect the inside of the unit from liquids and small metal objects. Incase of accident, unplug the power cord and have it serviced by anauthorized Service Center.5. Do not hit or scratch the panel surface as this causes flaws on the surfaceof the screen.6. For correct installation and mounting it is strongly recommended touse a trained, authorized dealer.7. As is the case with any phosphor-based display (like a CRT monitor,for example) light output will gradually decrease over the life of a PlasmaDisplay Panel.8. To avoid sulfurization it is strongly recommended not to place the unitin a dressing room in a public bath or hot spring bath.9. Do not use in a moving vehicle, as the unit could drop or topple overand cause injuries.10. Do not place the unit on its side, upside-down or with the screen facingup or down, to avoid combustion or electric shock.Plasma monitor cleaning procedure:1. Use a soft dry cloth to clean the front panel and bezel area. Never usesolvents such as alcohol or thinner to clean these surfaces.2. Clean plasma ventilation areas with a vacuum cleaner with a soft brushnozzle attachment.3. To ensure proper ventilation, cleaning of the ventilation areas must becarried out monthly. More frequent cleaning may be necessarydepending on the environment in which the plasma monitor is installed.Recommendations to avoid or minimize image retention:Like all phosphor-based display devices and all other gas plasma displays,plasma monitors can be susceptible to image retention under certaincircumstances. Certain operating conditions, such as the continuousdisplay of a static image over a prolonged period of time, can result inimage retention if proper precautions are not taken. To protect yourinvestment in this plasma monitor, please adhere to the followingguidelines and recommendations for minimizing the occurrence of imageretention:* Always enable and use your computer’s screen saver functionduring use with a computer input source.* Display a moving image whenever possible.* Change the position of the menu display from time to time.* Always power down the monitor when you are finished using it.If the plasma monitor is in long term use or continuous operation take thefollowing measures to reduce the likelihood of image retention:* Lower the Brightness and Contrast levels as much as possible withoutimpairing image readability.* Display an image with many colors and color gradations (i.e.photographic or photo-realistic images).* Create image content with minimal contrast between light and darkareas, for example white characters on black backgrounds. Usecomplementary or pastel color whenever possible.* Avoid displaying images with few colors and distinct, sharply definedborders between colors.Plasma monitor driving soundThe panel of the Plasma monitor is composed of extremely fine pixels andthese pixels emit light according to received video signals. This principlemay cause you to hear a buzz or electrical hum coming from the Plasmamonitor. Also note that the rotation speed of the cooling fan motor increaseswhen the ambient temperature of the Plasma monitor becomes high. Youmay hear the sound of the motor at that time.Note:The following items are not coverd by the warranty.• Image retention• Panel generated sound, examples: Fan motor noise, and electricalcircuit humming /glass panel buzzing.Contact your dealer for other recommended procedures that will bestsuit your particular application needs.Important Information
