Modes of Operation
The unit may be operated and controlled by three
different methods.
1. Via the dedicated front panel buttons
(The NRS70/75 is supplied in this mode)
Various selections may be made directly by a
single push of a button. e. g. INPUT Source.
Pressing the button again deactivates the function
and the button LED will turn off.
Holding down a button will reveal an appropriate
menu in the display window. e.g. PATTERN.
2. Via the RollCall menu Structure
Menus may be selected by the push buttons
adjacent to the display and further menu selections
made by rotating a spinwheel and pressing the
adjacent push button.
The spinwheel also allows continuously variable
parameters, e.g. Gain, to be adjusted and the
setting to be seen in the LCD window.
3. Via a PC using the RollCall Templates
All operational parameters and selections may be
made on the RollCall system via a PC.
