The data entry knob on the lower portion of the UFCP can perform which of the following?

• A. Decrements numerical values (counter clockwise rotation)
• B. Increments numerical values (clockwise rotation)
• C. Has a push-to-select function
• D. All of the above

Answer: (D)

The data entry knob is a multifunction control that lets you input numeric values efficiently. Rotating it clockwise increases the selected value, while rotating it counterclockwise decreases it. In addition, pressing the knob acts as a select/enter function to confirm the chosen value or move to the next field. Because it provides both incrementing and decrementing through rotation and a push-to-select action, all of these capabilities are part of the same control. So the best answer is that it can do all of the above. In practice, you dial in the value you want by turning, then press to confirm.
