enabled to navigate only within the present screen . When the

is absent, the cursor is disabled, and
navigation to other screens occurs with rotation of the encoder knob.
4.2.3 Selecting & Changing a Parameter
For display screens which access user-selectable parameters (and within which navigation is possible), the
cursor position is marked by a rectangle formed by thin yellow lines surrounding one of the adjustable
parameters in question. To enter any screen and
to make adjustments within the screen, it is first
necessary to momentarily depress the encoder knob to activate the cursor. Then, rotating the encoder
knob will move the cursor successfully through the adjustable parameters present on the screen (and only
the adjustable parameters) in both directions, in a wrap-around fashion. (Note that the “Exit Screen”
symbol
▲

automatically appears in the upper-right corner of the display when the cursor is activated.)
To change a parameter highlighted by the cursor, momentarily depress the encoder knob. The selected
parameter will change from yellow to green. With the parameter highlighted in green, rotation of the
encoder knob will change its setting. The change will be reflected in the operation of the
FMHD-1
immediately. To move to a different adjustment, momentarily press the encoder knob a second time. The
highlighted parameter will turn yellow, locking out further adjustment of that parameter. Subsequent
rotation of the knob will move the cursor through the other adjustable parameters present in the displayed
screen.
4.2.4 Exiting an Adjustment Screen
If the parameter marked by the surrounding yellow cursor is highlighted green, momentarily depress the
encoder to turn it yellow. Rotate the encoder knob until the cursor is at the

Exit Screen symbol at the
upper-right corner of the display. Momentarily depress the encoder knob. The
▲
▼
symbol will disappear.
Then, with the
▲ ▲
▼
symbol absent, rotation of the knob will advance the display to the next screen.
4.2.5 Entering a Popup Menu
Any of the popup menus may be entered through the popup menu selection pull-down, which is
accessible from any screen. A listing of the popup menus and the user-adjustable parameters they each
contain appears in Table 2, “
FMHD-1 Popup Menu Map”, on page 41.
Depress and hold in the encoder knob sufficiently long for the popup menu selection pull-down to appear.
(It is a blue and yellow pane in the upper right of the
FMHD-1 front-panel display.) The initial selection,
“RF” is highlighted, and appears in blue type against a yellow background. Other selections in the popup
menu selection pull-down are made by rotating and depressing the encoder knob (two rotational detents
per selection). Once the desired category has been highlighted, pushing the encoder knob momentarily
enters that category, typically offering multiple sub-categories of adjustable parameters.
The desired sub-category again is selected by momentarily depressing the encoder knob. If only a single
category is present, a parameter adjustment is then made by rotating the encoder until the desired choice
appears. If multiple categories are present, the encoder knob is used to navigate through a multi-parameter
blue pane to select the parameter to be adjusted. In the first case, when the knob selects the parameter
options directly, simply depressing the knob following the adjustment clears the popup menu, and returns
the user to the display screen.
In the case where a blue, multi-parameter popup menu pane appears, the cursor is automatically activated
and is placed at the first adjustable parameter in the pane. In the same manner as for the display screens, a
