3.11 Editing and Deleting DAC and TCG Reference Points
After your reference points are recorded, they may be individually deleted, their values may be manually adjusted, or new points may be
manually entered (as long as the total number does not exceed 16 points). To edit points or input additional points:
1. With the DAC/TCG menu accessed, select the EDIT submenu.
2. Activate the POINT function and select the desired point number (or NEW if adding a new point).
3. Activate the POINT POS. function and adjust (or input for NEW points) the horizontal position of the point.
4. Activate the POINT GAIN function to adjust (or input for NEW points) the applied gain (i.e. the vertical position) of the point. Note
that this adjustment applies regardless of whether the point is used for TCG reference or a DAC curve.
5. Activate the ENTER function to confirm the adjusted point values (or the position of a new point). The DAC curve or the TCG
reference function is adjusted to match the edited input.
6. To delete any single DAC point, press and hold the center of the joystick for the POINT , POINT POS , or POINT GAIN function while
the point to be deleted is active. When prompted, confirm the deletion. Note that the first point cannot be deleted, and that all DAC
curves must contain at least two points. Therefore, if a curve has only two points stored, neither can be deleted.
