Secure Operation

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.
