SAFETY&PRECAUTIONS
SAFETY CHECK AFTER SERVING
Examine the area surrounding the repaired location for damage or deterioration. Observe that screw, parts and wires have been returned to original positions. Afterwards, perform the following tests and conform the specified values in order to verify compliance whit safety standards. 1. Insulation resistance test Confirm the specified insulation resistance between power cord plug prong and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) isgreater than values given in table 1 below. 2. Dielectric strengthen test Confirm specified dielectric strengthen between power cord plug prongs and exposed accessible parts of the set (RF terminals, antenna terminals, video and audio input output terminals, microphone jack, ear phone jacks, etc.) is greater than values given table 1. 3. Clearance distance When replacing primary circuit component, confirm specified clearance distance (d), (d' between soldered terminals, ) and between terminals and surrounding metallic parts. See table below. Rating for selected areas

7. THE METHOD TO INITIALIZE THE VIDEO DATA
1. 2. 3. 4. 5. 6. 7. 8. When [484] is sequentially pressed in MENU mode, the SERVICE mode is activated. Choose " CHANGE OF VIDEO DATA"by pressing [3]. The input video signal should be PAL or null signal and the speed should be SP. Change A1 bytes to all " by the [ 1" ],[ ], [OK] buttons. The data are stored in EEPROM when [0] button is pressed. Pull out the mains power cord. Instantly short the both leads of C524 on MAIN PCB to reset the VCR. Plug in the mains power cord again.

8. THE METHOD TO CONTROL THE SERIAL DATA
1. Access to the SERVICE MODE by pressing [484] buttons sequentially in MAIN MENU. 2. Choose " CHANGE OF VIDEO DATA" by pressing [3]. 3. Then the data table which indicates the current video system (PAL/SECAM) and speed (SP/LP) is displayed on screen, while it detects the system and speed automatically. 4. Select the system and speed using [PAL/SECAM] button and [SP/LP] button on remote control if you need to change. 5. The cursor on the data table moves from right to left when the [ ] button is pressed. 6. The cursor on the data table moves from up to down when the [ ] button is pressed. 7. Data is toggled whenever the [OK] button is pressed on the cursor position. 8. If you need to change the data related to TRICK PLAY, it can be easily accessed in STILL mode. 9. First, the mode of the system detection should be AUTO mode after you change the data, and then if [0] button is pressed after this, the data of the current status are stored in EEPROM, then the SERVICE MODE MENU is displayed. 10. The data corresponding to the system, speed, input selection, trick play are not changed. * The group indication part on the data table is changed as in order of A1, A2, ... P1, P2, ... M1, M2, ... S1, S2, ... (SECAM ONLY) A1, A2, ... whenever the [PAL/SECAM] button on remote control is pressed, the system detection of which are A(AUTO), P(FORCED PAL), M(FORCED MESECAM), S(FROCED SECAM) respectively. * The data changed to the current system according to the input video signal automatically in case of AUTO mode and if no signal, it changes to PAL system. * Adjust the correct system by pressing the [PAL/SECAM] button on remote control if the current status of the system is not correspond to the input video signal.
