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.
