the

and more than one keyset is used (see Section 10.4.2), select this parameter to erase
keys in the currently active keyset before activating the currently inactive keyset.
(see Section 10.2.5).
Program Channel/Group PIDs and Encryption Type - With conventional analog
calls, this information is programmed on the channel screen. With other types, it is
programmed in the talk group list selected on the system screen. In addition, with
conventional digital calls, the group programming can be overridden on the channel
screen (see Section 10.3.3). Additional PIDs for special calls can also be specified on
the system screen for digital and trunked calls.
Note
The encryption type is not selectable on digital channels because the AES/DES mode is
determined by the key type loaded, not by PC Configure programming.
