Loss Indication

When you press the PTT button while in the coded mode and without
the encryption module containing a valid key, the speaker generates
bursts of alert tones, and the display shows KEY FAIL until you
release the PTT button.
When the radio is first turned on, six medium-pitched tones sound
and the display momentarily shows KEY FAIL to indicate that the
encryption module does not contain a valid key for the current mode.
If the periodic keyfail tone feature is enabled, six medium-pitched
tones are generated every five to ten seconds while the radio is not
transmitting or receiving to remind you that the radio does not have a
valid key for the current mode. The keyfail reminder will not sound
when the radio is in clear mode.
