Keys
Function
ENTER
This key will enter a submenu or enter an editing mode of a parameter. The Parameter
is only set once ENTER is pressed again otherwise changes will not be saved.
Commands such as reconfigure and reset will activate once the ENTER key is
pressed.
CLEAR
This Key will return to the previous display or exit out of an editing mode without
changing the parameter.
ST
These keys are used to navigate the menus. The
→
symbol on the display is used to
point to the current selection. The
↓↑
symbols on the display indicate options above
and below. On some menus with a large number of options then the selection will wrap
around. These keys can also be used when editing parameters either from a list or
numerically incrementing or decrementing values including hexadecimal. When a
parameter requires a +/- indicator then these keys are used to toggle between them.
WX
These keys are used to navigate a parameter value once it has been selected. The
X
key may also be used to enter a submenu in the same way as the ENTER key.
0 to 9
When editing a parameter field with a numerical value, these keys allow the number to
be entered directly.
Note
If a parameter is changed and the CLEAR key pressed before ENTER, the parameter change will be
cancelled and the display returned to parameter selection mode.
