1. Precaution

1. Precaution

Follow these safety instructions while servicing the ESD to prevent damage and to protect against potential hazardssuch as electrical shock and X-rays.

1.1. Safety Precautions

1) When reinstalling the chassis and its assemblies, be sure to restore all of the protective devices, including the controlknobs and the compartment covers.

2) Make sure that there are no cabinet openings through which people (particularly children) can make contact withdangerous internal components.

3) Design Alteration Warning : Never alter or add to the mechanical or electrical design of the unit.Example : Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard. Also, anydesign changes or additions will void the manufacturers warranty.

4) Leakage Current Hot Check Figure 1.1 AC Leakage Test :

WARNING

Do not use an isolation transformer during this test. Use a leakage-current tester or a metering system that complieswith American National Standards Institute (ANSI C101.1, Leakage Current for Appliances), and UnderwritersLaboratories (UL Publication UL1410, 59.7).

With the unit completely reassembled, plug the AC cord directly into a 120 V AC outlet. With the units power switchedfrom the ON to the OFF position, measure the current between a known ground and all exposed metal parts.Known Grounds - EarthKnown Metal parts - Screwheads, Metal Cabinets, etc.

1. Precaution

5) Insulation Resistance Cold Check :(1) With the units AC plug disconnected from the AC source, connect an electrical jumper across the two AC prongs.(2) Set the power switch to ON.(3) Measure the resistance between the shorted AC plug and any exposed metallic parts.

Example : Screwheads, Metal Cabinets, Antenna Port, etc. If any of the exposed metallic parts has a return path tothe chassis, the measured resistance should be between 1 and 5.2 megohms. If there is no return path, the measuredresistance should be infinite. If the resistance is outside these limits, a shock hazard might exist.See Figure 1.2 Insulation Resistance Test

Figure 1.2 Insulation Resistance Test

6) Components, parts and wiring that appear to have overheated or that are otherwise damaged should be replaced withparts that meet the original specifications. Always determine the cause of damage or overheating, and correct anypotential hazards.

7) Observe the original lead dress, especially near the following areas :Antenna wiring, sharp edges, and especially the AC and high voltage power supplies. Always inspect for pinched,out-of-place, or frayed wiring. Do not change the spacing between components and the printed circuit board. Check theAC power cord for damage. Make sure that no wires or components touch thermally hot parts.

8) Product Safety Notice :Some electrical and mechanical parts have special safety-related characteristics which might not be obvious from visualinspection. These safety features and the protection they give might be lost if the replacement component differs fromthe originaleven if the replacement is rated for higher voltage, wattage, etc.

9) Components that are critical for safety are indicated in the circuit diagram by shading, or .Use replacement components that have the same ratings, especially for flame resistance and dielectric strengthspecifications. A replacement part that does not have the same safety characteristics as the original might createshock, fire or other hazards.

1. Precaution

1.2. Servicing Precautions

1) Servicing precautions are printed on the cabinet. Follow them.

2) Always unplug the units AC power cord from the AC power source before attempting to :(a) Remove or reinstall any component or assembly, (b) Disconnect an electrical plug or connector, (c) Connect atest component in parallel with an electrolytic capacitor.

3) Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used.The internal wiring may be clamped to prevent contact with thermally hot components. Reinstall all such elementsto their original position.

4) After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure thatthe portion around the serviced part has not been damaged.

5) Check the insulation between the blades of the AC plug and accessible conductive parts (examples : metal panels,input terminals and earphone jacks).

6) Insulation Checking Procedure :Disconnect the power cord from the AC source. Connect an insulation resistance meter (500 V) to the blades of theAC plug. The insulation resistance between each blade of the AC plug and accessible conductive parts (see above)should be greater than 1 megohm.

7) Never defeat any of the B+ voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless allsolid-state heat sinks are correctly installed.

8) Always connect a test instruments ground lead to the instrument chassis ground before connecting the positive lead;always remove the instruments ground lead last.

CAUTION

First read the Safety Precautions section of this manual. If some unforeseen circumstance creates a conflict between theservicing and safety precautions, always follow the safety precautions.


1. Precaution

1.3. Precautions for Electrostatically Sensitive Devices (ESDs)

Some semiconductor (solid state) devices are easily damaged by static electricity.Such components are called Electrostatically Sensitive Devices (ESDs).Examples include integrated circuits and some field-effect transistors.The following techniques will reduce the occurrence of component damage caused by static electricity :

1) Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from yourbody by touching a known earth ground. Alternatively, wear a discharging wrist-strap device. (Be sure to remove itprior to applying powerthis is an electric shock precaution.)

2) After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to preventaccumulation of electrostatic charge.

3) Do not use freon-propelled chemicals. These can generate electrical charges that damage ESDs.

4) Use only a grounded-tip soldering iron when soldering or unsoldering ESDs.

5) Use only an anti-static solder removal device. Many solder removal devices are not rated as anti-static (these canaccumulate sufficient electrical charge to damage ESDs).

6) Do not remove a replacement ESD from its protective package until you are ready to install it.Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminumfoil or other conductive materials.

7) Immediately before removing the protective material from the leads of a replacement ESD, touch the protective materialto the chassis or circuit assembly into which the device will be installed.

8) Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, orlifting a foot from a carpeted floor can generate enough static electricity to damage an ESD.

5) After step (4), you can see on the VFD.Insert the Region Code (Below table) corresponding model with 0 ~ 9 buttons on the remote control.

6) After step (5), you can see 15 USA on the VFD.It means that currently System Micom program is installed by USA specification.

15 USA

7) Turn the Power off.

NOTE

In case of System Micom and EEPROM problem, you can apply to this.

For example, during Updating program of System Micom, if Updating fail is happened, it is impossible to turn on the systemfrom stand-by status.

The system will keep the stand-by status continuously, and the touch-key function will never work.

In this case, you have to change System Micom, and set up the Buyer Region code again. In case of EEPROM, you don'tneed to care about it.After set-up the Region code, System Micom will store the information of the region code to EEPROMautomatically.
