sounds.
If an attempt is made to change an analog channel
from the clear to the secure mode and there is no
available secure channel, "NO SEC" is flashed, an
error tone sounds, and the call is terminated.
If an attempt is made to change an analog channel
from the secure to clear mode, "SEC ONLY" is
