IMPORTANT NOTES
No.		Items	Notes
1	Arching sound from		A buzzing sound might be heard when the plasma display monitor is turned on in a very quiet
	plasma display monitor’s		room. This is due to the plasma panel drive circuit when it is functioning. This arching sound
	panel.		is normal and it is not a malfunction.
2	Interference for infrared		Some infrared rays are emitted from the plasma display monitor’s panel that might affect other
	equipment.		infrared controlling equipment.
3	Bright and dark spots		High-precision technology is used to manufacture the plasma display panel; But in some
			cases, there are minor defects in some parts of the screen. Points that do not light, points
			with brightness different from that of the periphery, points with color different from that of the
			periphery, etc. Some pixels will always be on or always off. Please note that this is not a
			malfunction.
4	Picture Image (Spectrum)		When receving still picture signals, (e.g. channel number indication or clock indication) for a
			while, you can see image-like when the picture varied. This is not a defect.
5	Display panel surface		The plasma display panel is lighting the phosphors by the discharge of internal radiation. In
		temperature is too high	some cases, this may cause the temperature of the panel surface to increase. Please note
			that this is not a malfunction. The Plasma TV surface temperature is higher than a
			Cathode-ray-tube.
6	Plasma Surface		The plasma panel is made from glass. Heavy shock on the front panel might damage it.
7	Transportation		When the PDP monitor is transported horizontally, the glass panel has the possibility of being
			broken or increasing the picture defects. At the time of transportation, horizontal style is
			prohibited. More-over, please treat the plasma panel with great care because of a precision
			apparatus. Please instruct transporters so that it should be put into the packing box at the time
			of shipment.(There is a possibility that breakage of the panel or defects will increase.)
			Rough transportation might cause damage to the panel and pixel failure.
8	Image retention		The plasma monitor illuminates phosphor to display images. The phosphor has a finite
			illumination life. After extended periods of illumination, the brightness of the phosphor will be
			degraded to such extent that stationary images would burn-in that part of the screen as
			grayed-out images. Brightness will decrease automatically during still and slightly
			moving pictures. This is not a failure. This is a special feature to avoid image retention.
			Tips to prevent such image retention are:
			- Do not display images having sharp brightness differences or hi-contrast images, such as
			monochrome characters and graphic patterns, for long.
			- Do not leave stationary images appearing for long, but try to refresh them at appropriate
			intervals of time, or try to move them using screen saver function.
			- Turn down the contrast and brightness controls.
9	Luminosity and contrast		PDP television has luminosity and low contrast compared with CRT television.
10	Granular spots		When a screen is seen at point-blank range, a random fine grain may be visible to a dark part.
11	Disturbance to video		If an apparatus (VCR, etc.) antenna line is arranged near the monitor, the image may shake,
	apparatus		or disturbance may be received.
12	Lip Sync		There is some time lag betweeen the picture and the sound. You can see lip motion that is
			delayed compared to the sound.
13	About the use		Electric discharge/luminescence characteristic of the PDP panel also changes with peripheral
	environment of PDP		temperature. Moreover, since there is also high power consumption value, a specified
		television (temperature)	temperature environment is required.
14	Caution on prolonged		Storing the plasma television for a period of more than 2 to 3 months without use might cause
	storage		an unstable picture when the set is turned on.
15	Operating		Operating altitude: 800 to 1,114hPa (6,194ft to -2,484ft). Operating temperature: 41˚F to 95˚F.
16	Storage		Storage Altitude: 300 to 1,114hPa (31,912ft to -2,484ft). Storage temperature: 5˚F to 140˚F.
17	Power ON or OFF		Frequent use of the Power ON or OFF might trigger the power protection circuit. If the TV
			does not turn ON, please wait a little before turning ON again.
