At CHILD LOCK mode, the TV is auto set blue screen and mute, the position is not watched V-CHIP (remote key) Function: to enter the V-CHIP menu 1) Instruction of the V- CHIP menu: 5

6 When the V-CHIP OPTION in the adjustment menu6 is set to 1, the V-CHIP function is selected, this key is acceptable. In the V-CHIP menu, pressing this key to select the each options, the POS+ or POSkey also can be used to select the options, the selected option is red, the other are cyan. After the option has been selected, pressing the VOL+ or VOL- key to change setup or to enter the next menu. If the V-PASSWORD in the adjustment menu6 is set to 1 in the adjust menu6, then the password function is used. The first line is PASSWORD in the V-CHIP menu, when the correct password is input (omnipotent password: 6568), then the first line is changed as NEW PASSWORD and the cursor is moved to next line. Set new password option: After the password has input, the first line is shown as NEW PASSWORD. Press the POS+/POS- key to set the cursor is in the first line, pressing the digital key to input the new password of four digitals. Then the fist line is shown as CONFIRM that s input the new password to confirm. If the password is the same, then the first line is shown as NEW PASSWORD OK, otherwise is not. Exit automatically menu when any operation is not executed over ten seconds. 2) Instruction of the TV Rating and MPAA Rating and the covered condition: There is two terms in order to cover some program: 1.The Block is set ON in the V-CHIP MENU; 2.The class of the related option of TV Rating or MPAA Rating menu is set B ; When the CPU detect that the signal is the Class of B, the screen is automatic blue and TV is automatic mute (the Block is On), and the OSD is the information.

The explanation of special function 5-1.The function of normal remote control unit realizing the factory 1).The operation method is shown below: First set the volume is 0, second press the MENU key to enter PICTURE menu, then press the digital key to input 6568, the factory function can be realized. 2).The fast method at FACTORY and B/W BALANCE and ADJUST mode: the SLEEP key is used to change among three modes, the RECALL key is used to exit from factory to normal. 5-2.Screen function The screen function is realized when the SCREEN OPT. is set to related value in the menu3. The waiting time of blank screen ( SCREEN TIME ) is set according to the different CRT. The setup mark is displayed in the process of waiting if the screen function has been set. If the screen left side isn t covered, please set the SCR.H.POSI. in the adjustment menu2 to the proper position. The hardware need be changed to produce the phase pulse of CPU if the best state isn t set. The screen function is not used if the screen is not adjusted Over modulation control function This function is selected when the OVER.MOD.SW is set to ON in the menu12. The V.LEV.OFFSET is used to offset to the video output, the OV.MOD.LEVEL is used to adjust the value. Only the fined position can be offset. 5-4.HOTEL mode The hotel mode is used when the HOTEL MODE in the menu6 is set to 1. The HOTEL VOLUME is used to set the volume, the ON POSITION is used to set the position number at hotel mode. 12

13 5-5.Only AV mode The only AV mode is used when the ONLY AV MODE is set to 1. The TV mode is not realized at only AV mode. Only the picture menu is displayed and the auto shut off function is canceled. 5-9.Factory mark and screen setup The factory mark is divided into two lines, it can set 16 characters every line. The content, switch, font, color and position can be set. The factory mark is set, and at least one line among them is set to TURN ON state. The factory OSD will be displayed when the screen is blue at no signal. If the POWER LOGO is set to ON, the screen function is displayed at POWER ON. 1).Operation explanation Press P.MODE key over 3 seconds to enter the factory mark setup mode. The factory menu have two screens, it is respectively used to adjust the first and second line. After entering the setting menu, press the POS+/POS- key to select the option, if the option is selected, there is the yellow piece on the screen to show the adjustment option. The other OSD that are selected are red, otherwise the OSD are cyan. Press the VOL+/VOL- key to select the value of selected option. The adjustment of display content: pressing the POS+/POS- key to select the adjustment item. The adjustment character is yellow and press the VOL+/VOL- key to adjust the content. The P.MODE key is used to select the other character at the same line. The OSD of menu is always displayed, pressing the DISPLAY key to exit after the setup finish. The factory mark is set to to see, to get. The display of content, color, font and position are the same as normal, except the display of that in the factory mode. So the result of adjusting can be directly seen. The setup of two lines content, please don t set to layer after layer, in order to prevent the abnormality. 2).OSD A LOGO2 ON SIZE 2*2 H.POS 20 COLOR RED V.POS 30 LOGO1 ON SIZE 2*2 H.POS 20 COLOR RED V.POS 30 A 5-10.The realization of automatic adjusting at factory The CPU pin25 is the ENABLE. It is set to high level in normal. When this pin is low level, the control right of CPU is handed by the automatic adjustment instrument after waiting 160ms. The automatic adjustment instrument can send the data through the BUS to adjust, the adjusted data must be written into the EEPROM. Then the ENABLE port come back to 13

14 high level, the CPU is normal after waiting about 500ms. The data about the automatic adjust and the address of EEPROM are shown below: The address of EEPROM: A0H The address of la76818: BAH Name Sub-address of EEPROM Sub-address of decode slice Max R.BIAS 1BH 07H FFH G.BIAS 1CH 08H FFH B.BIAS 1DH 09H FFH R.DRV 1EH 0AH 7FH G.DRV 1FH 0BH 0FH B.DRV 20H 0CH 7FH S.BRI 21H 0DH 7FH 14
