5.1. A Note on “Latching” Soft Keys:

The H9000 user interface has context-sensitive “soft keys” on the left and right sides of the display.

There are two different types of soft keys on the H9000:

  • “Normal” soft keys: These execute their labeled action when pressed.

  • “Latching” soft keys: When pressed, they change the front panel display to a different state. Think of the latching soft keys as a quick way to access “sub-menus” or alternate screens on the H9000.

Latching soft keys are visually distinguished by a small triangular “flag” in the top corner of the key.
