All cryptographic keys can be zeroed (erased from radio
memory) by pressing the MONITOR/CLEAR button and while still
pressing this button, press and hold the OPTION button. Press
both buttons for 2 seconds. A series of beeps will begin at the
start of this 2 second period and then switch to a solid tone
after the keys have been zeroed. The display will indicate "KEY
ZERO"
If the cryptographic key(s) are zeroed, one or more keys
must be transferred from the Keyloader into the radio before
private communications may continue.

When receiving, the radio automatically switches between
clear or private operation. If the transmission being received is
an encrypted transmission, it will be decrypted, the
flag will flash, the receiver will unsquelch and the message will be
heard in the speaker. For this to occur, the selected group or
channel must be programmed for private operation and the
correct cryptographic key must be loaded into the radio.
