There are three basic uses of the function keys:
• To navigate from screen to screen
• To toggle a selection
• To pop-up a selection menu
Navigation
In the Opening screen, the function keys are used to navigate between the vari
-
ous measurement screens. For example, pushing [F1] in the Opening screen will
take you to the Coupler screen.
Toggle
In a measurement screen, when a selection for a function key has only two pos
-
sible options, pressing the function key will toggle between those options. For
example, a function key setting the ear tested will toggle between “left” and
“right.” A red box will appear briefly around the function key box on the dis
-
play. This box means that the selection is in the process of being toggled.
Pop-up Menu
In a measurement screen, when there are several possible selections to be made
with a function key, pressing the function key will bring up a pop-up menu.
When this happens, use the [∨, ∧] keys to select the desired setting, and then
use [>] to perform the actual selection.
For example, in the Coupler screen, pressing [F5] will bring up a selection of
source types. To select the desired source, you would use [∨, ∧]. To complete the
selection, you would press [>].
