SAFETY PRECAUTIONS
GENERAL GUIDELINES
1. It is advised to insert an isolation transformer in the
AC supply before servicing a hot chassis.
2. Always use the manufacturer’s replacement safety
components. The critical safety components marked
with on the schematics diagrams should not be
by other substitutes. Other substitute may create the
electrical shock , fire or other hazards. Take
attention to replace the spacers with the originals.
Furthermore where a short circuit has occurred ,
replace those components that indicate evidence of
overheating.
3. After servicing , see that all the protective devices
such as insulation barriers, insulation papers, shields
and isolation R-C combinations are correctly
installed.
4. When the receiver is not being used for a long time
of period of time , unplug the power cord of the
Adaptor from the AC outlet.
PDP Module is very sensitive
both electrically and physically.Users,
therefore, are requested to follow the
“Guidance of handling color PDP
Module”on the followings.
1-Be careful not to make scratch on the
polarizer.
Surface of polarizer is soft and can be physically
damaged easily.Please do not touch, push or rub
polarizer surface with materials over HB hardness.
2 - Keep clean the surface.
Please wear rubber glove when touch the surface of
PDP screen. Please use soft and anti-static material
as cleaner.
3 -Keep out of water.Water on/in the PDP may
cause electrical short or corrosion. Please wipe out
dry or water carefully.
4 -Prevent swift Temperature & Humidity
change.Instantaneous temperature and/or humidity
change can make dew or ice which cause
nonconformance such as malfunction.
5 - High temperature & high humidity
reduce the life-time.
PDP is not proper to be used at high temperature
and high humidity. Please keep specified
temperature and humidity condition.
6 - Keep out of Corrosive Gas.Corrosive gas
effect the polarizer and the circuit chemically and
cause defects accordingly.
7 - Electrostatic discharge can make
Damage
There are electro-static sensitive components
in PDP Module. Please earth human
body when handle the PDP.In addition, please do
not touch the interface connector pinwith bare.
8 - Do not operate for a long time under
the same pattern
Operating PDP for a long time under the same
pattern can cause image persistence and can
damage it. Please follow following guidance.
1. Turn the power off when do not use.
2. Change the pattern periodically.
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper
between the two prongs of the plug.
2. Turn the receiver’s power switch.
3. Measure the resistance value with an ohmmeter,
between the jumpered AC plug and each exposed
metallic cabinet part on the receiver. When the exposed
metallic part a return path to the chassis the reading
should be between 4Mohm and the 20Mohm. When the
exposed metal does not have a return path to the chassis,
the reading must be infinite.
LEAKAGE CURRENT HOT CHECK
1. Plug the AC cord directly in to the AC outlet. Do
not use an isolation transformer for this check.
2. Connect a 2Kohm 10W resistor in series with an
exposed metallic part on the receiver and an earth,
such as a water pipe.
3. Use an AC voltmeter with high impedance to
measure the potential across the resistor.
4. Check each exposed metallic part and check the
voltage at the each point.
5. Reverse the AC plug at the outlet and repeat each of
the above measurements.
6. The potential at the any point should not exceed 1.4
Vrms. In case a measurement is outside the limits
specified , there is the possibility of a shock hazard ,
and the receiver should be repaired and rechecked
before it is returned to the customer.

Important information
Read and heed the notes on safety so that no hazard to your health arises during contractual use. Errors during
installation and connection can damage the device or subsequently related devices.
Always keep the operating instructions within reach. Heed the warnings on the device and in the operating
instructions.
• General reference
Before you connect the plasma display, please carefully
read throught the general notes on safety and the
operating instructions. Only in this manner can you
utilise all functions safely and reliably.
As far as possible, keep the operating instructions
together with the device so that you can use it to look
up information.
Heed the warnings on the device and in the operating
instructions.
Never allow children to utilise electrical devices without
supervision.
• Operation
The plasma TV acquired by you, meets the highest
quality codes and standards to be found in this
business segment. A plasma display consists of a
multitude of so called pixels. One pixel consists
of 3 elements (red, green and blue). Even using
the highest quality control practices during the
manufacture of the displays, it can not be 100 %
excluded that some pixels or pixel elements will
be defective. These defects may appear as
permanent illuminated pixels, non illuminating
pixels or unstable pixels (flickering) respectively.
We therefore ask for your understanding when
we declare that these defects are not covered
under the warranty liability. This is valid insofar
that the sum of all defective pixels or pixel elements
does not exceed 0,01 % of the total amount.
The brightness and contrast of plasma displays
decreases with time.
Plasma displays are phosphor based and under
certain operating conditions, so-called “Burn-
In” effect may occur. This is in fact a degrigation
of the phosphor and is a natural process in plasma
technology.
Such operating conditions are:
- static images being displayed for long periods
- continues display of the same background
- use of a non full screen format (e.g. 4:3) for a long
periods.
Once Burn-In has occurred it is normally irreversible.
To avoid or to reduce the Burn-In effect, please
follow the listed recommendations:
- Please use moving images or continuous moving
static images in full screen format (slide show)
during the first 100 hours of operation
- Please use your plasma TV in a full screen format
(16:9)
- In case the plasma display is used as a PC monitor,
please use moving images
- Always switch the screen off, if it is not in use
- Decrease contrast and brightness as much as
possible
- If possible display images with maximum colour
depth and scale
Certain conditions may cause a humming noise in the
displays electonics. This is usually caused by the mains
power supply having different ground wires. One
remedy for solving this problem is to insert a filter
between antenna cable and antenna input. These filters
are available at all specialised trade outlets.
If the plasma display is connected to an external
antenna, it has to be grounded to protect against
electrical hazards and static discharges. The grounding
must conform and be in accordance with the actual
regulations in force.
• Environmental conditions
Never operate the plasma display under
environmental conditions which differ from those
of the technical data. Divergent conditions can lead
to endangerment, fire or breakdown of the device.
Protect the plasma display against moisture. This
pertains to permanent high humidity, the proximity
ta water, water drops and water splashes as well
as rain. Do not place any water-filled containers
(e.g. vases) on the device.
Protect the device against heat. Avoid the proximity,
to fire, heating devices, ovens or permanent exposure
to direct sunlight.
Protect the display against heat accumulation. Do
not cover the ventilation slots. Maintain a distance
of at least 10 cm above and below the ventilation
from sides 4 cm from rear 4 cm slots as well as
laterally to furniture and to the ceiling. Do not furnish
the device with curtains.
The display is designed for mounting in landscape
format on walls or installations.
• Mains connection
The mains input and the mains switch are located
on the rear side. The mains input is located on the
upper right and the mains switch is placed in the
upper middle. For safe disconnection of the display
from the mains voltage, the mains switch is to be
turned off and the mains cable is to be removed
from the mains input module.
Connect the plasma display only to a socket with
earthing contacts installed according to regulations,
and whose main voltage conforms with the device’s
technical data. See to it that the mains plug and
the socket are accessible at all times. Install the
mains cable in such a fashion that nobody can get
caught in it. Use only the supplied mains cable.
Protect it against damages, and do not make any
alterations to it. Never use a damaged mains cable.

• Signal inputs
Always turn the plasma display and the signal
source off before you establish a connection between
both devices.
• Disturbances
In the event of damages to the mains cable or the
device, immediately pull the mains plug from the
socket.
Under no circumstances should you attempt to open
and/or to repair the device yourself. Instead,
contact our Service Hotline or another suitable
professional workshop.
• Batteries
Batteries can be life-threatening when swallowed.
That’s why you should safeguard batteries from
the reach of small children. Immediate medical
assistance should be utilised if a battery has been
swallowed.
Always take the exhausted batteries out of the
remote control immediately, since these leak and
can cause damage as a result.
The enclosed batteries may not be charged or
reactivated by other means, not taken apart, thrown
in fire or short-circuited.
TO FULLY DISCONNECT THE TV, SWITCH OFF
THE MAINS SOCKET AND REMOVE THE
POWER PLUG.
Exhausted batteries do not belong in household
waste. The batteries must be disposed of at the
collection points provided for this purpose.
• Cleaning and maintenance
Before cleaning, turn the device off, and pull the
mains plug from the socket. Wait a few minutes
so that the capacitors in the device can be
completely discharged.
Use only a slightly dampened, soft cloth for cleaning.
You should avoid chemical solvents and cleaning
agents, because these can damage the surfaces.
• The plasma display generates high voltage internally
for the gas discharge. Turn the device off and pull
the mains plug from the socket during installation,
maintenance and repairs. Wait a few minutes so
that the capacitors in the device can be completely
discharged.
• In case foreign elements such as water, liquids,
metal parts, etc. get into the plasma display, pull
the mains plug out immediately. Never attempt to
touch anything inside the device with any kind of
objects. The danger of an electric shock or accident
exists.
• Pull out the mains plug immediately if smoke,
unpleasant odour or unusual noises are emitted
from the device. Also proceed in the same manner
if the display is no longer able to present an image
after being turned on or during operation. Never
attempt to continue operating the display in this
condition.
• In the event of lengthy absence or during
thunderstorms, pull the mains plug from the socket,
and pull the house antenna socket from the antenna
jack.
• Never plug-in or pull-out the mains plug with wet
hands. Never operate the mains switch with wet
hands.
• Utilise only the supplied mains cable. Protect it
against damages, and do not make any alterations
to it. Never use a damaged mains cable.
• The plasma display has a glass surface. Should
the device be subjected to excessive loading (e.g.
through shock, vibration, bending and heat shock),
the glass surface can break. Do not subject the
glass surface to any pressure or shock. Should the
glass be broken, immediately pull the mains plug
and do not touch the broken glass with bare hands.
• When the plasma display has been switched to
the stand-by mode it is still connected to the mains.
You must switch the mains switch into the 0 position
or pull the mains plug from the socket for complete
disconnection.
• For ergonomic reasons it is recommended to avoid
using red and blue fonts or symbols on dark
backgrounds. Such a display causes poor
readability due to the lower contrast, and
prematurely fatigues the eyes. Therefore, please
use high-contrast displays as much as possible,
e.g. black font on a white background.
• During the connection of external laudspeakers,
pay attention to the loudspeaker output technical
data. In the event of insufficient dimensioning of
the loudspeaker, the loudspeaker and/ or the built-
in amplifier can be damaged.
• Packaging and packing resources which are no
longer needed are able to be recycled, and should
always be turned in for recycling.
• Place the carton upright with the underside on firm
ground. You will recognise the top side by the
direction of the arrowheads on the longitudinal
side
• The plasma display may only be mounted on
vertical (plumb) walls by means of the wail
mounting unit. Before beginning the mounting,
make sure that the display is turned off and the
mains cable and signal cable are unplugged.
The backgraund has to be firm and structurally
able to carry a load. Appropriate materials are
to be utilised for varying wall superstructures,
such as wooden walls or hollow-space walls. If
there’s any doubt, contact your responsible sales
or service department.
