File name 02_Precaution.pdf 1. Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including : control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people--particularly children --might insert fingers and contact dangerous voltages. Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers. If the measured resistance is less than 1.0 megohm or greater than 5.2 megohms, an abnormality exists that must be corrected before the unit is returned to the customer. 4. Leakage Current Hot Check (See Fig. 1-1) : Warning : Do not use an isolation transformer during this test. Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7). 5. With the unit completely reassembled, plug the AC line cord directly the power outlet. With the unit's AC switch first in the ON position and then OFF, measure the current between a known earth ground (metal water pipe, conduit, etc.) and all exposed metal parts, including : antennas, handle brackets, metal cabinets, screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse the power-plug prongs in the AC outlet and repeat the test. 6. X-ray Limits : The picture tube is designed to prohibit X-ray emissions. To ensure continued X-ray protection, replace the picture tube only with one that is the same type as the original. DEVICE UNDER TEST TEST ALL EXPOSED METER SURFACES 2-WIRE CORD ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) EARTH GROUND LEAKAGE CURRENT TESTER (READING SHOULD NOT BE ABOVE 0.5mA) Fig. 1-1 AC Leakage Test 7. Antenna Cold Check : With the unit's AC plug disconnected from the AC source, connect an electrical jumper across the two AC prongs. Connect one lead of the ohmmeter to an AC prong. Connect the other lead to the coaxial connector. 8. High Voltage Limit : High voltage must be measured each time servicing is done on the B+, horizontal deflection or high voltage circuits. Heed the high voltage limits. These include the X-ray protection Specifications Label, and the Product Safety and X-ray Warning Note on the service data schematic. 9. 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. 10. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. Alternat | |||||||||||||||

2. Alignment and Adjustment 2-1 VCR Adjustmant 2-1-1 Adjustment Preparation 1) Before you start OE Use the buttons on the SET key when adjusting VCR. ´ When changing the adjustment item, please press the "EASY-Q" and "DISPLAY" buttons on the Set. You can change the adjustment value to move the "MENU Dial" Up or Down. ¨ Press the push the "ENTER button" when storing confirmed adjustment value of each adjustment step in EEPROM. ^ The OSD shows "OK" after finishing each adjustment step. Ø To clear the adjustment mode, pull out the power source. 2) Function of each buttons on the Set Key Buttons ENTER button (Confirm) MENU Dial down (Data Down) MENU Dial up (Data Up) EASY-Q (Mode Up) DISPLAY (Mode Down) 3) How to get into the VCR adjust mode [STEP 1] OE Connect the Power source. ´ Set the Power Switch to "PLAYER" position and Mode Switch to "TAPE" position. EASY-Q Button STOP Button Power Switch Description Stores changed value in the adjustment and auto adjustment mode. Changes data in the adjustment state. Changes mode. MENU Button MENU Dial ENTER Button Mode Switch DISPLAY Button PB ZOOM Button Fig. 2-1 Samsung Electronics 2-1 Alignment and Adjustments [STEP 2] OE Press and hold the "STOP" and "PB ZOOM" buttons on the video camera at the same time for more than 5 seconds. ´ When monitor OSD appears as shown Fig. 2-2, the adjustment mode has been activated successfully. Move the "MENU Dial" to highlight VCR ADJ and push the "MENU Dial". ¨ Monitor OSD shows Fig. 2-3. Then VCR adjustment mode has been activated successfully. [STEP 3] If you want to finish the adjustment mode, you have to do Power Reset. The Power Reset means that you pull out the power source and pull in it again.
