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 de-
crypted, the
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.

Transmitting An Encrypted Call

1. Select the desired group or channel.
2. Place the radio in private mode by pressing the
key. When private mode is enabled, the
PVT
status flag will be on.
If the last state of the radio was private mode, the
private mode will be enabled on power up. Also the
private mode will be enabled if forced operation has
been programmed in the radio.
If a group or channel is not programmed for private
mode operation, "PVT DIS" will be displayed if an
attempt is made to enable private transmit mode. It
is not possible to operate on this group/channel in
private mode.
