Safety cautions

The matters to be observed without fail are explained below. These matters are indispensable for the

prevention of an accident during the maintenance servicing, the "security of products" after the completion of

servicing work, and the "prevention of the repeated occurrence of similar fault."

(1) The degree of danger and material damage, caused as a result of wrong use by disregarding the contents

of the display" is distinguished and explained in the table below.

(2) Kinds of the matters to be observed are classified and explained in the icons shown below.

· Be careful of an electric shock or a burn.

· The power block or the PDP module involves the sections where high voltage or high

temperature is prevalent. When equipment is energized, use working gloves in order to

prevent an electric shock or a burn. At the time of transportation, disassembly,

reassembly, and the replacement of parts, such a servicing job must be done after pulling

out the power plug.

If this display is disregarded and equipment is handled

wrongly, this can be a cause of physical injury and a

fire, thus leading a person to death or serious injury.

If this display is disregarded and equipment is

handled wrongly, this may lead to personal injury or

material damage.

This icon indicates the contents of "caution" that must be borne in mind, without fail.

This icon indicates the contents of "caution" that must be practiced, without fail.

This icon indicates a dangerous place where an electric shock is anticipated.

· The replaced parts and wiring must be arranged in the original conditions.

· For safety reasons, insulation materials like tubes and tapes may be used or some parts

may be mounted clear of the PWB. The internal wiring and the fastening with the

clampers for separation from high-heat and high-voltage parts shall be returned to their

original conditions, without fail.

· Modification of equipment is absolutely prohibited. Use the specified parts at all times.

· If any modification is performed, the validity of the manufacturer's warranty is lost at that

moment. The personnel who did this modification is responsible for the physical injury or

the like, if it should occur as a result of the modification. The parts used are given the

safety-based characteristics, such as non-flammability or sufficient withstand voltage. The

parts to be replaced shall be those which are specified in the list of replacement

parts.(Example: The lithium battery (circuit symbol BA9501 in the MAIN PWB) will give

rise to explosion if its polarity is wrongly treated.

· Observe the caution matter, without fail.

· In the place where a particular caution is needed during maintenance servicing, such a

caution note is displayed with a label or a stamp that is given to the cabinet, chassis,

PWB, etc. These caution notes and also the caution matters of

given in

the instruction manuals, etc., must be observed, without fail.
