Key Zero
All cryptographic keys can be zeroed (erased from
radio memory) by pressing the MONITOR/CLEAR but-
ton and while still pressing this button, press and hold
the OPTION button. Press both buttons for 2 seconds. A
series of beeps will begins at the start of the 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.
Private Operation
Receiving An Encrypted Call
When receiving, the radio automatically switches be-
tween clear or private operation. If the transmission
being received is an encrypted transmission, it will be
decrypted, the
icon will turn on, 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 cryp-
tographic key must be loaded into the radio.
