Turn on the monitor and allow a warm up period for Approx. 15 Min. 2. Set the front panel controls for Maximum Contrast setting and Center Brightness setting. 3. Confirm that the unit is converged. Otherwise, perform a convergence adjustment before continuing. 4. Input a MEME INVERTED test pattern (white background and black characters) in the Mode 1 (1024x768) timing standard. Any text based windows screen may be used for the test pattern if required 5. Adjust the FBT focus control: VR1 and CRT socket focus control: VR2 to obtain the clearest characters possible. Use the FBT control to adjust the center focus. Use the neck control to adjust the corners. Then go back and forth as needed to optimally focus the entire screen. 6. Check focus on Modes 2 - 8 to verify correct focus on all timing modes. 7. Secure both of the focus adjustment controls with RTV adhesive (P/N 7-322-065-19). Allow RTV curing time of 24 hours.

What is the correct Extended Display ID (EDID) data for this monitor ? Solution: Then please use the EDID Data Table given on the following page to verify correct EDID data stored in this monitor. The DAS EDID Editor operation is described in Service Bulletin CSI-111 No. 112. EDID data is in Hexadecimal form. Hexadecimal numbers have a small “h” ending for clarity. Use Windows 3.1 or Windows 95 Calculator Functions (or equivalent) to convert Decimal numbers to Hexadecimal and vice versa. Select the “DEC” Mode, and enter the Decimal Number. Then Select the “HEX” Mode to convert the entry to a Hexidecimal Number. Reverse the procedure to convert a Hexadecimal Number to a Decimal Number. The following NOTEs (*1 - *4) apply to the EDID Data Table. NOTE *1: Serial Number for DDC is 4 byte of data in Hexadecimal form. LSB first. Example: Label Serial Number: 6601234 is in Decimal Number form. Convert Decimal Number: 6601234 to Hexadecimal Number. 0064BA12h NOTE *2: Week of Manufacture for DDC is 1 byte of data in Hexadecimal form. Convert Decimal Number: 1 to 53 into Hexadecimal Number 01h to 35h. NOTE *3: Year of Manufacture for DDC is 1 byte of data in Hexadecimal form. Year Code = AD - 1990 in Hexadecimal form. Example: Year Code for 1995: 1995 - 1990 = 05 which converts to 05h. NOTE *4 Checksum is 8 bit data for 1 byte of DDC data. Use Lower 8 bit of the sum of the DDC data for preceding data Numbers 0 to 126. Cont. Reference: S. Tatsui, J.
