digital COFDM factory default Presets or from your own custom
digital COFDM Presets. The selected Preset will be used as a
“make-from” to prepare the new digital COFDM Preset
configuration.
Please note that while factory default COFDM Presets may be
used to prepare a new Preset configuration, these factory
default Presets cannot be changed or deleted. They can only
be used as “make-froms”.
When the new configuration is prepared using the factory default
Preset, it cannot be saved with the factory Preset number or
Preset name. A new Preset number and Preset name must be
assigned to the new Preset.
When using a custom Preset as a “make-from”, the new Preset
should be saved with a new Preset number. When you save the
new Preset, the Preset number will automatically be increased to
the next available Preset number. If you select an existing
Preset number when saving the new Preset, the original custom
Preset will be overwritten and cannot be recovered. The only
way to restore a Preset that has been overwritten is to re-enter
the custom Preset data from scratch.
If you are updating configuration settings on an existing custom
Preset, when you save the configuration settings, the Preset
number will automatically be increased to the next available
Preset number. You must enter and save the configuration
settings using the original Preset number.
