Selecting a Keyset
This feature allows you to select one or more groups of several
encryption keys from among the available keys stored in the
radio.
For example, you could have a group of three keys structured to
one keyset, and another group of three different keys structured
to another keyset; by changing keysets, you would
automatically switch from one set of keys to the other.
Every channel to which one of the original keys was tied now
has the equivalent new key instead.
