Important user information
Plasma display protection function
When still images (such as photos and computer images) stay on
the screen for an extended period of time, the screen will be slightly
dimmed. This is because the protection function of the plasma
display automatically adjusts the brightness to protect the screen
when detecting still images; so this does not designate
malfunction. The screen is dimmed when a still image is detected
for about three minutes.
Information of pixel defect
Plasma screens display information using pixels. Pioneer plasma
display panels contain a very large number of pixels. (Depending
on the panel size: over 2.3 million cells in case of a 42 inch display;
over 3.1 million cells in the case of a 50 inch display). All Pioneer
display panels are manufactured using a very high level of ultra-
precision technology and undergo individual quality control.
In rare cases, some pixels can be permanently switched off, or on,
resulting in either a black or colored pixel permanently fixed on the
screen.
This effect is common to all plasma displays because it is a
consequence of the technology.
If the defective pixels are visible at a normal viewing distance of
between 2.5 meters and 3.5 meters whilst viewing a normal
broadcast (i.e. not a test card, still image or single color display)
please contact the supplying dealer.
If, however, they can only be seen close up or during single color
displays then this is considered normal for this technology.
Infrared rays
The plasma display releases infrared rays because of its
characteristics. Depending on how the plasma display is in use,
the remote controls of nearby equipment may be adversely
affected or wireless headphones using infrared rays are interfered
by noise. If this is the case, place that equipment at a location
where its remote control sensor is not affected.
Radio interference
While this product meets the required specifications, it emits a
small amount of noise. If you place such equipment as an AM
radio, personal computer, and VCR close to this product, that
equipment may be interfered. If this happens, place that
equipment far enough from this product.
Plasma display driving sound
The screen of the plasma display is composed of extremely fine
pixels and these pixels emit light according to received video
signals. This principle may make you hear buzz sound or electrical
circuit humming from the plasma display.
Do not attach such items as labels and tape to the product
This may result in the discoloration or scratch of the cabinet.
When not using the product for a long period of time
If you do not use the product for a long period of time, the functions
of the product may be adversely affected. Switch on and run the
product occasionally.
Condensation
Condensation may take place on the surface or inside of the
product when the product is rapidly moved from a cold place to a
warm place or just after a heater is switched on in winter morning,
for example. When condensation takes place, do not switch on the
product and wait until condensation disappears. Using the
product with condensation may result in malfunction.
Cleaning the surface of the screen and the glossy surface
of the front cabinet
When cleaning the surface of the screen or the glossy surface of
the front cabinet, gently wipe it with a dry soft cloth; the supplied
cleaning cloth or other similar cloths (e.g., cotton and flannel). If
you use a dusty or hard cloth or if you rub the screen hard, the
surface of the product will be scratched.
If you clean the surface of the screen with a wet cloth, water
droplets on the surface may enter into the product, resulting in
malfunction.
Cleaning the cabinet
When cleaning the cabinet of this product, gently wipe it with a
clean soft cloth (e.g., cotton and flannel). If you use a dusty or hard
cloth or if you rub the cabinet hard, the surface of the cabinet will
be scratched.
The cabinet of this product is mostly composed of plastic. Do not
use chemicals such as benzene or thinner to clean the cabinet.
Using these chemicals may result in quality deterioration or
coating removal.
Do not expose the product to volatile gas or fluid such as pesticide.
Do not make the product contact with rubber or vinyl products for
a long period of time. The effect of plasticizer in the plastic may
result in quality deterioration or coating removal.
If you clean the surface of the cabinet with a wet cloth, water
droplets on the surface may enter into the product, resulting in
malfunction.
Handles at the rear of the plasma display
Do not remove the handles from the rear of the plasma display.
When moving the plasma display, ask another person for help and
use the handles attached to the rear of the plasma display. Do not
move the plasma display by holding only a single handle. Use the
handles as shown.
Do not use the handles to hang the product when installing or
carrying the product, for example. Do not use the handles for the
purpose of preventing the product from tilting over.
Fan noise
The rotation speed of the cooling fan motor increases when the
ambient temperature of the plasma display becomes high. You
may hear the sound of the fan motor at that time.
