With the power turned OFF, press the POWER button while press- ing the TAPE MONITOR button and VIDEO 2 button simulta- neously to turn ON the power. 2. ALL CLEAR ! will be displayed on the fluorescent indicator tube, and ALL CLEAR will be executed. FACTORY SET Mode which sets the memory of the unit to the setting of adjustment and check at factory. (Not used for servicing.) Method: 1. With the power turned OFF, press the POWER button while press- ing the SPEAKER button and TAPE button simultaneously to turn ON the power. 2. FACTORY SET will be displayed on the fluorescent indicator tube, and FACTORY SET will be executed. Note: In case you return the unit to the customer, do not perform FACTRY SET. If you do it, perform ALL CLEAR. Fluorescent indicator tube, LED all lit mode and key check mode Method: 1. With the power turned OFF, press the POWER button while press- ing the TAPE MONITOR button, VIDEO 1 button, and VIDEO 2 button simultaneously to turn ON the power. 2. The fluorescent display tubes and LEDs will all light up. 3. The display will change as follows each time buttons other than GENRE and MODE are pressed. Therefore, it can be checked if buttons have been input properly by whether the display changes. Adjustment of OSD Screen Position The position of the screen can be adjusted freely to correct the devia- tion of the OSD screen caused by the monitor type that users are using. 1. Move the cursor of the remote commander attached, and display the OSD screen. 2. Click the MAIN MENU FUNCTION of the OSD screen. 3. Next click TV SET. 4. Next click GRAPHIC POSITION SET. 5. The screen for adjusting the OSD screen position will be displayed. Adjust the position with the remote commander attached. 6. Click EXIT to end. *1 Those other than the POWER LED go OFF. 4. To exit the mode, press the POWER button to turn OFF the power. Fluorescent indicator tubes, LEDs are all lit Press any button Partial lighting of fluorescent indicator tube 1, LEDs are OFF *1 Press any button Partial lighting of fluorescent indicator tube 2, LEDs are OFF *1 Press any button Press any button Fluorescent indicator tube and all LEDs are OFF *1 N N N N NNNNN RadioFans.CN 收音机爱 好者资料库 4 SECTION 2 GENERAL This section is extracted from instruction manual. 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 1Screw (BVTP 3x8) 7Flat type wire (21 core) (CNS402) 6Flat type wire (17 core) (CNJ203) 5Flat type wire (21 core) (CNS702) 8Front panel assembly 2Screw (BVTP 3x8) 3Screw (BVTP 3x8) 4Remove the connector Note: Follow the disassembly procedure in the numerical order given. 3-1. FRONT PANEL ASSEMBLY SECTION 3 DISASSEMBLY 23 SECTION 4 ELECTRICAL ADJUSTMENT Video Frequency Adjustment Connection: OSD board JW10 (FS CHECK) frequency counter Method: 1. Press the POWER button without connecting anything to the ex- ternal input terminal (VIDEO IN etc.). 2. Adjust CT202 of the OSD board so that the reading on the fre- quency counter becomes 17.734475 MHz 40 MHz. OSD Width Adjustment Connection: SET Monitor TM201 !PIN (GROUND) Method: 1. With the power turned OFF, press the TAPE MONITOR button and VIDEO 2 button simultaneously and turn on the power. The position of the OSD image set by the user will be cleared and set to position set at shipment. 2. The OSD function frame will be displayed on the monitor. This screen will disappear in a few seconds automatically when the input of codes using the remote commander stops. If it disappears during adjustments, move the cursor of the at- tached remote commander. The screen will appear again. 3. While watching the monitor screen, adjust CT201 of the OSD board so that the following standard is satisfied. TM201 !PIN (VIDEO) monitor screen BA OSD function frame NOTE: Extra margin is provided in this adjustment in consideration of the deviation of the screen according to the type of monitor used. Consequently, the user is able to adjust the position of the screen freely. (For details, refer to “Adjustment of OSD Screen Position” in 1. Service Note. Refer to page 3.) Adjustment standard: Adjust so that the width A of the OSD function frame becomes the same as space B of the monitor screen. 24 Adjustment Location: S.
