Precautions regarding use
Panel sticking and after-image lag
Displaying the same pictures such as still images for an
extended time may cause after-image lagging (burn-in).
This may occur in one of the following two cases.
1. After-image lagging due to remaining electrical load
W
hen 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 disappears when moving images
are displayed. The time for an after-image to disappear
depends on the luminance of the still images and the length
of 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 do not disappear
completely.
The same kind of burning of an image may also be produced
after extended multi-hour use, recurrent daily use for shorter
periods of a [4:3] screen size, or by a [DOT BY DOT] image.
Except in cases where violation of intellectual property rights
may be involved (pages 21 and 22), avoid selecting a screen
size that displays images over the entire screen.

In addition, use [ENERGY SAVE] function (page 31), [ORBITER]
function (page 29), [MASK CONTROL] function (page 29), and
[SCREEN MGT.] (page 30) to reduce the chance to lag-image
formation.
Note
Special precautions must be employed when using the
plasma display panel as a surveillance monitor or in other
applications where a fixed image is displayed for extended
periods of time. Before using the monitor in such situations,
consult your dealer or installer for advice.
When using this unit as a monitor for a surveillance
camera, set the [ENERGY SAVE] function to
[MODE3] or [MODE2].
About the plasma panel’s protection function
The brightness of this display deteriorates slightly when an
image with little movement such as a photograph or computer
image is continuously displayed. Image deterioration is caused
by the panel’s protection function which detects images with little
movement and automatically adjusts brightness to protect the
display; this is not a malfunction.
The screen-saver function senses when the display detect little
or no screen movement for a period of approximately three
minutes. This function is an automatic feature and cannot be
turned OFF.
Pixel failure
The plasma display screen is composed of a large numbers of
tiny pixel elements constructed in a high-precision array. 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.
Concerning infrared light
In principle, the plasma panel radiates infrared light. Depending
upon the installtion site's environment, wireless headphones may
may experience noise or infrared remote controls for other nearby
tdevices may fail to function properly. Move the affected device or
headphone connection point to another 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.
Additional cautions
•
If the power automatically turns OFF during operation, one of
the following reasons may be the cause.
1
[POWER MANAGEMENT] function may not be set to [ON]
(page 24).
2
The surrounding temperature has risen above 40 °C.
The display should be used in an ambient temperature
below 40 °C.
3
The internal temperature has risen abnormally high due to
blocked cooling vents, overheating of internal electronic
parts, or other factors.
If the power automatically turns OFF for a reason other than
the above reasons, there could be a malfunction. In this case,
unplug the power cord from the outlet and request service from
your nearest dealer or authorized service organization.
•
The plasma display panel of this unit is very bright. Viewing from
a short distance causes eye strain.
We recommend that you view the screen from a suitable
distance of 10 to 20 feet (3 to 6 m) away.
•
To protect the panel and internal circuitry, this display includes
a cooling fan designed to turn ON/OFF and automaticaly change
speed in accordance with ambient temperature fluctuations (fan
sound changes as the speed adjusts).
This plasma display panel should be used within an ambient
temperature range below 40 °C.
STANDBY and ON indicators
During operation of the [POWER MANAGEMENT] function, the
ON indicator flashes green at intervals of approximately 1 second
(page 24).
The ON 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 35).
If the green light displays a flashing pattern other than that described
previously, it indicates an error. Check any on-screen messages
(page 34) and ambient conditions (temperature, etc.) then respond
accordingly (page 35).
If the problem persists, disconnect the power plug and consult
your dealer or a service center.
If the power turns OFF by itself, refuses to turn ON, or causes the
STANDBY indicator to flash red, a malfunction may be indicated.
Immediately disconnect the power and consult your dealer or an
authorized service center.
