Theymight damage to cause panel surface variation and color change(4)Do not apply any strong mechanical shock to the PDP panel2-2 Precaution of Operation:(1)Please be sure to unplug the power cord before remove the back-cover. (make sure the power isturn-off)(2)Please do not change variable resistance settings in PDP MODULE; They are adjusted to themost suitable value. If they are changed, it might happen LUMINANCE does not satisfy.(3)Please consider that PDP MODULE takes longer time to become stable of radiation characteristicin low temperature than in room temperature.(4)Please pay attention to displaying the same pattern for very long-time. Image might stick on PDP.
