Using the Front Panel Push-buttons
MX-2100 operation is controlled by means of the display and the three
pushbuttons designated CURSOR, SCROLL and ENTER.
The same control actions are consistently used for all the activities:
•
CURSOR
- You use this push-button to indicate what you want to change.
Pressing the CURSOR push-button moves the cursor among the fields in the
current display. The cursor is a bar that underlines the selected field.
Some fields list several different items, and then you move the cursor under
the desired item. The item above the cursor will be changed (“scrolled”) when
you press SCROLL.
•
SCROLL
- Press repeatedly to display the alternatives for the current field/item
indicated by the cursor. Holding the push-button depressed causes automatic
scrolling of the available alternatives.
•
ENTER
- Press it once to select the value displayed in the field/item indicated
by the cursor.
Pressing ENTER also confirms the selection of all the other values in the group
being currently displayed in the top row, e.g., SYSTEM, LINK, etc. For CH
PARM, the pressing of the ENTER push-button confirms the parameters
selected for all the channels of the current module. Therefore, you need to
press ENTER only once for each parameter group, or for each module.
