When we first picked up our Elektra it appeared to have a few missing phrases. We reset the pot for the speech on the squawk/talk board and picked up the phrases that are in the lower registers of the male voice - I believe reset balanced out the background pulse/volume/speech and we were able to hear missing phrases like "Cruising on Alpha", "Will you return?", and one related to the 3rd level, maybe about time expired.
Our Elektra also sports an Alltek Ultimate MPU (really like that board), switches relative to sound are set to liberal so all feature and background sounds, as well as attract are enabled.
FWIW
