There is several areas in the
Settings menu
screen:
–
Settings menu title
– shown the path to
currently selected menu item. Note that parameter name has to be considered in the context
of settings menu title. For example
Settings>Tuner - Frequency
is different from
Settings>Logger>Channel 1 – Frequency
.
–
Navigation area
– the selection of certain branches /
parameters is made here. The selected item is drawn in highlighted color. The names of the branches
or parameters are listed oh the right side of the navigation area. The value of the parameter is
shown on the right – against the parameter name. Since branches have no values associated with
them the tree dots are shown instead. This indicates a sublevel branch or parameter.
Button assignments:
OK – Acts differently depending on current selection. If selection is:
•
Menu branch – the transition to selected branch is made and the branch items are listed in
navigation area;
•
Menu parameter – the value of that parameter is highlighted and edit mode is entered;
•
Menu complex parameter (such as
Alarm
) – the parameter editor is shown and edit mode is
activated;
Up/Down – If edit mode is active – changes the value of the selected parameter. Otherwise will
move selection in corresponding direction up/down.
Left/Right – Changes selection within parameter value in edit mode. See examples below.
SB4
– Back one level or cancel menu mode.
There is several parameter types available in DB4004. The way of editing depends of that type.
Following is description of parameter types. Every parameter has several properties, change step,
unit, default value, permitted range for its value and so on.
Numerical parameter
(
INT
). Represents numerical value.
Example:
The value of the
frequency
can be changed
in 87.00 to 108.00 MHz range with step of 10, 20, 50 or 100 kHz;
Button assignments for
INT
in edit mode:
OK – Accept the value and exits edit mode.
Up/Down – Changes the value of the parameter with one step increment/decrement. The value
always stays in permitted parameter range.
SB4
– Discards the value and cancels edit mode.
Enumerated parameter
(
ENUM
). Represent selection of one value from set of predefined
enumerated values.
Example:
The value can be changed between “
Auto
”,
“
OFF
”, “
-10dB
” , “-
20dB
” and “
-30dB
” position.
Button assignments for
ENUM
in edit mode:
OK – Accept the value and exits edit mode.
Up/Down – Cycles through possible value positions. The value always stays in permited
parameter range.
SB4
– Discards the value and cancels edit mode.
