2PrecautionsPlease read this manual carefully before using your plasmamonitor and keep the manual handy for future reference.CAUTIONRISK OF ELECTRIC SHOCKDO NOT OPENCAUTION: TO REDUCE THE RISK OF ELECTRICSHOCK, DO NOT REMOVE COVER. NOUSER-SERVICEABLE PARTS INSIDE.REFER SERVICING TO QUALIFIEDSERVICE PERSONNEL.This symbol warns the user that uninsulatedvoltage within the unit may have sufficientmagnitude to cause electric shock.Therefore, it is dangerous to make any kindof contact with any part inside of this unit.This symbol alerts the user that importantliterature concerning the operation andmaintenance of this unit has been included.Therefore, it should be read carefully inorder to avoid any problems.WARNINGTO PREVENT FIRE OR SHOCK HAZARDS, DO NOT EXPOSETHIS UNIT TO RAIN OR MOISTURE. ALSO DO NOT USETHIS UNIT’S POLARIZED PLUG WITH AN EXTENSION CORDRECEPTACLE OR OTHER OUTLETS, UNLESS THEPRONGS CAN BE FULLY INSERTED. REFRAIN FROMOPENING THE CABINET AS THERE ARE HIGH-VOLTAGECOMPONENTS INSIDE. REFER SERVICING TO QUALIFIEDSERVICE PERSONNEL.Warnings and Safety PrecautionThis plasma monitor is designed andmanufactured to provide long, trouble-free service.No maintenance other than cleaning is required.Please see the section “Plasma monitor cleaningprocedure” on the next page.The plasma display panel consists of fine pictureelements (cells) with more than 99.99 percent activecells. There may be some cells that do not producelight or remain lit.For operating safety and to avoid damage to the unit,read carefully and observe the following instructions.To avoid shock and fire hazards:1. Provide adequate space for ventilation to avoid internalheat build-up. Do not cover rear vents or install the unitin a closed cabinet or shelves.If you install the unit in an enclosure, make sure thereis adequate space at the top of the unit to allow hot airto rise and escape. If the monitor becomes too hot, theoverheat protector will be activated and the monitor willbe turned off. If this happens, turn off the power to themonitor and unplug the power cord. If the room wherethe monitor is installed is particularly hot, move themonitor to a cooler location, and wait for 60 minutes tocool the monitor. If the problem persists, contact yourdealer for service.Important Information2. Do not use this unit’s polarized plug with extension cordsor outlets unless 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 tomodify the power cord.5. Unplug the power cord during electrical storms or ifthe unit will not be used over a long period.6. Do not open the cabinet which has potentially dangeroushigh voltage components inside. If the unit is damaged inthis way the warranty will be void. Moreover, there is aserious risk of electric shock.7. Do not attempt to service or repair the unit. Themanufacturer is not liable for any bodily harm or damagecaused if unqualified persons attempt service or openthe back cover. Refer all service to authorized ServiceCenters.To avoid damage and prolong operating life:1. Use only with 100-240V 50/60Hz AC power supply.Continued operation at line voltages greater than 100-240 Volts AC will shorten the life of the unit, and mighteven cause a fire hazard.2. Handle the unit carefully when installing it and do notdrop.3. Set the unit away from heat, excessive dust, and directsunlight.4. Protect the inside of the unit from liquids and smallmetal objects. In case of accident, unplug the powercord and have it serviced by an authorized ServiceCenter.5. Do not hit or scratch the panel surface as this causesflaws on the surface of the screen.6. For correct installation and mounting it is stronglyrecommended to use a trained, authorized dealer.7. As is the case with any phosphor-based display (like aCRT monitor, for example) light output will graduallydecrease over the life of a Plasma Display Panel.8. To avoid sulfurization it is strongly recommended not toplace the unit in a dressing room in a public bath or hotspring bath.9. Do not use in a moving vehicle, as the unit could drop ortopple over and cause injuries.10. Do not place the unit on its side, upside-down or with thescreen facing up or down, to avoid combustion or electricshock.Plasma monitor cleaning procedure:1. Use a soft dry cloth to clean the front panel and bezelarea. Never use solvents such as alcohol or thinner toclean these surfaces.2. Clean plasma ventilation areas with a vacuum cleanerwith a soft brush nozzle attachment.3. To ensure proper ventilation, cleaning of the ventilationareas must be carried out monthly. More frequent cleaningmay be necessary depending on the environment in whichthe plasma monitor is installed.Recommendations to avoid or minimize phosphor burn-in:Like all phosphor-based display devices and all other gasplasma displays, plasma monitors can be susceptible tophosphor burn under certain circumstances. Certainoperating conditions, such as the continuous display of astatic image over a prolonged period of time, can result inphosphor burn if proper precautions are not taken. To protect
