To edit a saved preset, you must load that preset from the
Presets
page (see “Loading Presets”
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” on page 2-
51 ).
In the top banner, 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, click the
Save
button and then click 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 in “Understanding the preset tabs” on
page 2-53 .
To remove a preset, select it and press the
Delete
button.
To ignore any changes, press
Cancel
to return to the
Presets
page.
NOTE:
See “Preset examples - IBOC preset” on page 2-59 , “Preset examples - Analog preset” on
page 2-59 , “Preset examples - IBOC preset with analog backup” on page 2-60 and “Preset
examples - DRM preset” on page 2-60 for sample presets for different transmission modes.
Loading Presets

of the transmitter are displayed.

Presets
page to display a window containing a list of other presets. Select
the desired preset and click the
Load
button to view or enable editing of the preset. Click the
Cancel
button to close this window.
