SERVICE SAFETY PRECAUTIONS
· The caution items shown here describe major safety issues and should always be observed. · The meanings of the various indications are as follows.

WARNING CAUTION

Indicates a hypothetical situation in which service personnel and nearby third parties, or even end users due to a product defect after the service operation is completed, could possibly be in danger of injury or even death in the event of operational error. Indicates a hypothetical situation in which service personnel and nearby third parties, or even end users after the service operation is completed, could possibly be in danger of injury, or where there could be physical damage in the event of operational error.

Examples of marks The > indicates caution (including danger and warning). The actual meaning of this caution is indicated inside the > or nearby illustrations or text. The example shown to the left indicates the danger of "electrical shock".

SHOCK HAZARD

PROHIBIT DISASSEMBLING

The indicates a forbidden action. The actual meaning of this caution is indicated inside the or nearby illustrations or text. The example shown to the left indicates that disassembly is forbidden.

UNPULUG

The a indicates a forced action (an action that must be performed). The actual meaning of this forced action is indicated by a or nearby illustrations or text. The example shown to the left indicates that the power plug must be disconnected.

GENERAL ADJUSTMENTS

WARNING
GENERAL ADJUSTMENTS
· Always advise users to keep children away. There is danger of injury to children from tools, disassembled products, etc.

KEEP CHILDREN AWAY
· Always disconnect the power plug before starting work whenever power is not required. Failure to disconnect the power plug before starting work can result in electrical shock.

UNPULUG
· Depending on the model, use an insulation transformer or wear gloves when servicing with the power on, and disconnect the power plug to avoid electrical shock when replacing parts. In some cases, alternating current is also impressed in the chassis, so electrical shock is possible if the chassis is contacted with the power on. · Always use the replacement parts specified for the particular model when making repairs. The parts used in products have the necessary safety characteristics such as inflammability, voltage resistance, etc.; therefore, use only replacement parts that have these same characteristics. Use only the specified parts when the * mark is included in a circuit diagram or parts list. · Parts mounting and routing of the wiring should be the same as that used originally. For safety purposes, insulating materials such as tubing or tape is sometimes used and printed circuit boards are sometimes mounted floating. Also make sure that wiring is routed and clamped to avoid parts that generate heat a
nd which use high voltage. Always follow the original scheme. · After a repair has been completed, reassemble all disassembled parts, and route and reconnect the wiring, in accordance with the original scheme. Do not allow internal wiring to be pinched by cabinets, panels, etc. Any error in reassembly or wiring can result in electrical leakage, flame, etc., and may be hazardous. · After completing the work, disconnect the power plug from the outlet, remove the antenna, turn on the power switch. Then, use a 500V insulation resistance meter to check the insulation resistance of the antenna terminal, other metallic parts and between the prongs of the power plug to make sure that the insulation resistance is 1M or more. The set will require inspection and repair if the insulation resistance is below this value. · Never remodel the product in any way. Remodeling can result in improper operation, malfunction, or electrical leakage and flame, which may be hazardous

About Permanent after-image · Due to the characteristics of a plasma screen, if the same image is displayed for an extended period of time, permanent after-image (image retention) in part of the screen may result. As a result of accumulative effect, brightness deterioration results. To prevent permanent after-image, it is recommended not to display the same image for an extended period of time, or in 4:3 mode. If retention occurs, display a moving picture like a video movie. This may After-image appear help to reduce minor permanent after-image. But it cannot be removed entirely once it has occurred. If the same static picture is displayed frequently, it is recommended to decrease "Brightness," or to adjust the Long life setting. Note on operations in 4:3 mode · In 4:3 mode, because of the sharp contrast between the displayed image area and non-displayed image area (frame), permanent after-image is likely to result. Therefore, we recommend adjusting the TV settings as follows: 1.Reduce "Contrast" and "Bright
ness" of the picture. The more you reduce, the more effect is effective. 2. Adjust the brightness of the side panels. The more you turn the brightness high, the more effect is effective. However, after adjusting the above settings, permanent after-image may not be removed entirely; only the onset of afterimage is delayed. Display your TV in Super Live or Wide mode as much as possible. Some parts of the screen do not light up · The plasma display panel is manufactured using an extremely high level of precision technology, however sometimes some parts of the screen may be missing picture elements or have luminous spots. This is not a sign of a malfunction. About infrared rays · The plasma screen of this unit emits infrared rays in normal operation, and may influence some infrared-operated equipment by a use state although the measures of infrared ray (filter, etc.) are taken. Locate such equipment carefully to prevent rays from the plasma screen causing any problems. About Interference · Plasma display may cau
se interference in image, sound, etc. of other electronic equipment that is easy to receive electromagnetic waves (i.e. AM radios and video equipment) under certain installed condition. In particular, it may affect electronic equipment beyond the residential unit where a plasma display TV is used. About Static electricity · If you touch the surface of the screen panel, you may feel a slight electric shock. This is harmless. About using under the low temperature places · If you use the TV in the room of 0°C or less, the picture brightness may vary until the plasma monitor warms up. This is not a sign of a malfunction. About disposal · Dispose the TV depending on the related local rules or laws.
