Selecting Keysets
This feature allows you to select one or more groups of 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 can 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.
Procedure:
1 Press the Kset menu item.
If the Multi-system Over-the-Air Rekeying feature is in use, the displayed keysets are only for the
current secure profile of the selected channel.
