Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by
pressing the c button (System Model) or C (Scan Model) and while
still pressing this button, press and hold the o button (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.
