Editing or creating presets using the AUI
When a presets page is opened from the main menu, the
Current Settings
of the transmitter are
displayed. They define the current operational state of the transmitter.
Current Settings
can be
edited and then immediately activated by pressing the
Save
button.
To edit a saved preset, you must load that preset from the
Presets
page (see Loading presets using the
AUI on page 2-52 ). If the edited preset was active before it was edited, saving the preset will update
the preset, but the
Current Settings
will not change. To update the operation of the transmitter, re-
activate the preset through the top banner (see Activating presets using the AUI on page 2-52 ).
In the top banner (see Figure 2.38 on page 2-52 ), an asterisk (*) appears next to the preset name when
the
Current Settings
have changed since the last preset was loaded.
Current Settings
are not saved
through an ac power cycle; when the transmitter recovers from an ac power loss, it loads the preset
that was last activated.
On the
Presets
page, an asterisk (*) appears next to the preset name in the header when there are
unsaved changes to the preset.
When changes are complete, press the
Save
button and then press the
Save Preset
window’s
Save
button to enable the changes. If you are creating a new preset, you can also enter a new name (e.g.,
Preset 4 - IBOC) in the preset window before clicking the
Save
or
Save New
button.
Parameters that can be edited are discussed in detail below.
To remove a preset, select it and press the
Delete
button.
To ignore any changes, press
Cancel
to return to the
Presets
page.
