Notes
In the following steps, if a factory default digital ASI
Preset was used as a “make-from” to prepare this
custom Preset, the Preset Text text box and the
Preset Number text box must be changed. You
cannot change or overwrite any factory default
Presets!
If a custom digital ASI Preset was used as a
“make-from” to prepare this custom Preset, a brief
description of the custom Preset should be entered
in the Preset Text text box for easy identification
purposes. The Preset number must be changed
only if you do not wish to overwrite the custom
Preset.
28. Select the Preset Text text box and enter a unique
digital ASI Preset description.
Note
If you used a factory Default Preset or a custom
User Preset as a “make-from” and you want to add
the new Preset to the list of User Presets
contained in your MTX5000 IDU, you must know
the highest user Preset number contained in your
IDU. To add the new Preset to the list of User
Presets, go to step 29.
If you used a custom User Preset as a “make-
from” and you want to use it to replace (overwrite)
an existing custom User Preset, go to step 31.
