The colored film permits each voltage output to be in one of three groups. Later in the FC-72 board, the three groups of voltages are matrixed to produce a color picture. The output of the CCD imager consists of the voltages from each phototransistor. The CCD imager requires vertical, horizontal and gate input pulses to output each voltage. All of these pulses come from the timing generator on the FC-72 board. The horizontal (H1, H2) and gate V Out pulses (RG) are required to step each row of voltages out of the CCD imager (CCD Out). After the row has exited, the remaining rows of volt- ages are shifted down to the exit row using four sets of vertical pulses (V1-V4).

Oscillator Circuit

The main backlight oscillator parts are bipolar transistor Q860 and trans- When the backlight is powered ON, 4.9V is applied via Q861 to R873 to former T851. Resistors R866 and R867 provide bias to the bases of turn on the infrared start LED D901. When the tube lights up, current is Q860. The collectors of Q860 feed 17Vp-p to T851. When this section drawn through ground resistor R872 causing a small voltage of 3.2Vp-p. receives voltage, it oscillates at about 92kHz. The frequency is not as This voltage is rectified into DC by D853 and detected by IC852. IC852 important as the voltage that is produced by T851. With an input voltage turns off Q861 to disconnect voltage to the D901 start LED. Therefore of 17Vp-p, T851’s output is 750Vp-p, more than enough to start the tube the infrared start LED is ON only prior to the ND901 tube lighting. glowing.

Start Up

Concept As the ND901 tube gets older, more voltage is required to trigger the tube into starting, especially at low ambient (surrounding) light levels and/or low temperatures. To insure reliable starts (and therefore extend the tube’s operating life), an infrared LED is placed next to the tube to increase the photon activity within the tube when the backlight is powered up. By in- creasing the photon activity, less voltage is required to start the tube, offsetting the aging process to a degree., BL CN801/CN701 PK 52 BD.

If you have a version of Radar W earlier than 2.1, uninstall it before in- stalling this version. 1. Open Control Panel. 2. Select Add/Remove Programs. 3. Select Radar W. 4. Select Add/Remove to remove the program. 5. Delete the Folder “C:\Radar W\” from your Hard Drive. You have to do this manually from the Windows Explorer. xiv, xv

Using Radar W - Version 2.1 Model selection

Clicking on Model selection brings us to the Model selection screen. When Radar W is launched from the Start menu, an initial screen similar to this one will be displayed. This screen identifies the Radar W version (2.1) and the previous camera model selected. Model name - Choose your model from the pull-down selections. Destination - Choose the country code for the country in which the model is sold. U2 is the country code for the United States. Port Address - The address to which your PC’s parallel port is assigned. This should always remain the same once it is set. NTSC / PAL - Choose the video output format of your model. To Menu - Once your model selection is completed, click the “To Menu” button to return to the Main Menu. When you place the mouse on the desired selection, the text turns purple.

Data handling

Model selection - The model that applies is shown at the top when Radar W is opened. Click on Model selection to change the model. You should Click on “Data handling” to enter the screen for uploading or downloading start here to begin using Radar W. data from the camera. A sample screen is shown. Data handling - Permits you to upload EEPROM data from the camera Three main purple-colored buttons: into the computer for storage and/or download this or default data from · Restore - Returns the data values to their previous state if they have the computer. This is useful when a board is replaced. been changed Adjustment - Some camcorders use this section to adjust switching pulse · Read - Uploads the EEPROM data from the camera and places it on position, camera AGC gain, Hall, and Focus to name a few. the screen in the boxes to the left. · Write - Downloads the uploaded or default* data to the camera. * Test menu - Permits you to test the camcorder’s pushbuttons, display Default data is not available at this time. emergency codes (failure history), and program a test sequence like play for 10 seconds, rewind for 5 seconds, FF for 5 seconds and repeat. Printer Setting - Allows you to switch from the default printer if you want a hard copy of the viewed page., This screen is used to do all uploading and downloading of data. We will give an example now of the Upload/Download process. Upload Example To upload the data from the camcorder, press the purple Read button. The following sample screen containing data will be displayed. Above the Purple Buttons Above the three purple buttons is a drop down menu. This allows you to move a single piece of data, a whole page or all the pages. The choices from the drop down menu are All page, 1 page and 1 Data. All page means restore, read or write data to all pages of both EEPROMs. 1 page means to restore, read or write data to 1 page. 1 Data means to restore, read, or write data to a specific address. This is the data from the camera under test. You can now save the cam- Below the Purple Buttons era data into your computer in the next steps. The buttons below the three purple buttons show you an individual Page, Saving the Data Address and Data value that you selected. These buttons can be used to linearly increase or decrease the data at the location selected. The buttons above the table permit you to move the on screen data or import default camera data. To the left of these buttons the data values are also displayed in a table format for each page. The page tabs are on top. When a data value is Click on Save of Data. A new screen will appear, telling you where it is clicked, the data on that page is selected to appear under the purple going to put the camera data (along the top). From this screen you can buttons for adjustment. put in a file name (10 digits max) for future identification like the camera’s serial number. Type the serial number into the box under the words File The adjustments from the service manual are listed in a window below Name as shown. the Address selection buttons. After you are done, click on the Save button. This saves the file in a folder under the Model Name within the Radar W folder. xvi, xvii Downloading Example After replacing the main camera board, you need to write that data back into the camera on the new board. 1. Begin by clicking on “Load of Data” above the table. This completes the Upload/Download process. 2. From the Data Load screen, select the file (named by serial number) that you want to load into the camera. 3. From the same Data Load screen, click the Load button. This will bring you back to the Data handling window but the data has not been loaded yet. 4. From the Data handling screen, download the data into the camera by clicking the Write button.,

Adjustment The following Execution End screen will appear. Click OK. This ends the

adjustment and returns you to the Adjustment menu. This section allows us to perform some camcorder adjustments. Select Adjustments from the Main Menu to begin. The following window ap- pears:

Test Menu

The Test section of the Radar W Main Menu is for camcorders. When Test is chosen the following window appears with three options: Select the adjustment that needs to be performed. We will choose SW.P. Adjustment (Auto) by clicking on it. Follow the instructions in the dialog box such as” insert the reference tape and click OK when complete”. Function button check - When you press a camera button, the button’s function will be highlighted on the screen. This is useful for troubleshoot- ing switch problems. Periodically, window(s) behind the dialog box will appear showing the steps that are being followed during the automatic adjustment. They can be Diagnosis - Will bring up a window that shows you the Self-Diagnostic ignored. history and the present Emergency codes. You can also clear the emer- gency information from this screen. xviii, xix Auto-Test - Intended for scripting sequences. A script would contain an operation that the camcorder would complete such as Play 10 seconds, Rewind 5 seconds and Stop. The camcorder can then be set to repeat this sequence an infinite number of times.
