4 Alignment and Adjustments This section of the service manual explains how to make permanent adjustments to the monitor. Directions are given for adjustments using the monitor Interface Board Ver. 2.0 and software (Softjig). 4-1 Adjustment Conditions Caution: Changes made without the Softjig are saved only to the user mode settings. As such, the settings are not permanently stored and may be inadvertently deleted by the user. 4-1-1 Before Making Adjustments .
4 Alignment and Adjustments 4-1-3 Connecting the SoftJig Connect the monitor to the signal generator and/ or PC as illustrated in Figures 4-1 and 4-2. Note: The signal cable connector which includes the 3-wire cable must connect to the monitor. If you use Setup 2 (PC only, no signal generator) you can only make adjustments to the signal timing available on that computer system. To make corrections to all factory timings requires the use of an additional signal generator. MONITOR INTERFACE BOARD VER. 2.
