Key Zero

All cryptographic keys can be zeroed (erased from radio memory) by pressing the cbutton (System Model) or C (Scan Model) and while

still pressing this button, press and hold the obutton (System Model) or O (Scan Model). Press both buttons for 2 seconds. A series of warning 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.

Private Operation

Receiving An Encrypted Call

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 PVT keylight (System Model) or OPTION keylight (Scan Model) 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.

Transmitting An Encrypted Call

1.Select the desired group or channel.

2.Place the radio in private mode by pressing the PVT button (System Model) or O (Scan Model). When private mode is enabled, the PVT keylight (System Model) or OPTION keylight (Scan Model) will be ON.
