7.4 Select an Encryption Index
This feature lets the user select one or more groups of several encryption keys from among the
available keys stored in the radio. For example, the radio could have a group of three keys structured
to one index, and another group of three different keys structured to another index. Changing indices
makes the radio automatically switch from one set of keys to the other. Every channel to which one
of the original keys was tied will now have the equivalent new key instead.
