5.11 Changing Feature Key
The feature key unlocks optional features or other modulation standards. It is an alpha-
numeric number. Changes to the feature key are only needed if additional features or
modulation standards are purchased. Contact your Harris sales representative for a
quotation. A new feature key is not required to reload existing software or to load an
updated version of existing software.
Changing modulation type, adding GPS, SFN or MH options require new feature keys.
The LCD control panel on the VAX-C can’t be used to enter a new feature key. The
feature key must be installed using the web GUI. The GUI screen containing the feature
key is shown in Figure 3-25 on page 3-41.
