| | ==== Extendable Legs ==== |
| | The SLICE-QTC has four extendable legs (<imgref belly>). Extending the front legs allows easy viewing from above (<imgref qt_prod_shot>) and extending the rear legs (<imgref side>) allows easy viewing from below. |

| In most instances, there are two methods for entering parameter values: the physical rotary knobs on the front panel and the pop-up keypad on the touch screen. When using the knobs to change the value of a parameter, changes take effect immediately. When using the keypad, changes do not take effect until the enter key is depressed. | In most instances, there are two methods for entering parameter values: the physical rotary knobs on the front panel and the pop-up keypad on the touch screen.

| If you touch an editable field for a brief moment, a cursor will appear under one of the digits of the parameter value. By turning the right knob, it is possible to increase (cw) or decrease (ccw) the value of the underlined digit. Turning the left knob will change which digit is editable (cw to move to the left and ccw to move to the right). | If you touch an editable field for a brief moment, a cursor will appear under one of the digits of the parameter value.

| It is possible to control the SLICE-QTC from a Windows<sup>®</sup>-based PC using a GUI. In order to use the GUI, you must first download the latest version, connect the PC to the SLICE-QTC, and assign a COM port to the SLICE-QTC. The following describes the steps involved. | It is possible to control the SLICE-QTC from a Windows<sup>®</sup>-based PC using a GUI.
