Key Select

(ASTRO Talkgroup List, Talkgroup List)

Selects the secure encryption key to be used while operating in secure encryption mode for the current talkgroup. This selection applies for the current talkgroup (record / row) of the current ASTRO Talkgroup List.

When the KMF Profile Index field is not "Disabled" for the current ASTRO Talkgroup List, this Key Select value is chosen from the Secure Hardware Encryption Key References List of the Secure KMF Profile selected in the KMF Profile Index field.

Be aware that the CPS is actually pointing to the Keys of the Encryption Key List for this selection; individual Keys from the Secure Hardware Encryption Key References List reference the Encryption Key List's Keys from the Hardware Key Reference field. Therefore any key selected When the KMF Profile Index field is not "Disabled", must first be defined in the Secure Hardware Encryption Key References List.

When the KMF Profile Index field is "Disabled" or not applicable (grayed-out) for the current ASTRO Talkgroup List, this Key Select value is directly chosen from the Secure Encryption Key List.

When the Secure Operation field is set to "Hardware" or "Advanced Digital Privacy", and

when the Voice Secure / Clear Strapping field is set to "Secure" or "Select", and

when the radio is model / option capable.
