Five different sensitivity curves are available to select from
(curves 1 through 5). Sensitivity curve 1 is the default curve
and causes the function speed to increase or decrease
equally with an equal amount of movement of the controller
(Figure 4-154).
Selecting a sensitivity curve of 2 through 5 causes the
function speed to be reduced, from the default sensitivity
curve 1, relative to the same controller position over the full
travel of the controller (Figure 4-155).
Sensitivity curve 1 (default) is the most sensitive and
sensitivity curve 5 is the least sensitive (Figure 4-156).
Adjust the sensitivity of a controller function by doing the
following:
1. Using the Jog Dial or Arrow Buttons on the Navigation
Control Pad, select the controller function icon that is to
be adjusted (icon will turn orange).
2. Press the Jog Dial or OK Button on the Navigation
Control Pad to make the controller function icon active
(icon background will turn gray).
3. Using the Jog Dial or the Up/Down Arrow Buttons, select
one of the five possible sensitivity curves (Figure 4-156).
4. Press the Jog Dial or OK Button to accept the new
setting.
Select the Reset All icon (5, Figure 4-153) on the Controller
Sensitivity function screen and press the Jog Dial or the OK
Button to set the sensitivity of all functions to the factory
default setting (default setting = Curve 1).
