receive clear or digital signals. Private (encrypted)
messages cannot be received when the radio is
in Aegis digital mode.
Aegis Private Mode (Optional)
The Aegis private mode allows the radio to
transmit and receive encrypted messages. To
operate in this voice mode, the radio must be
equipped with the optional encrypt/decrypt fea-
ture and the transmitting and receiving units must
have identical cryptographic keys.
Cryptographic keys are transferred into the
radio using a cryptographic Keyloader. Up to six
(6) different cryptographic keys, numbered 1 - 6,
can be transferred from a Keyloader and stored
in the radio.
On trunked systems, individual keys are auto-
matically selected from either the per-group cryp-
tographic key (for group calls) or the per-system
cryptographic key (for special and dynamic re-
group calls).
VGE radios require a VGE Keyloader (option
V4028 with software version 2.N or later). See
LBI-31685 for operating details on the VGE Key-
loader.
When operating on a group or channel pro-
grammed for private mode, all transmissions will
be private transmissions and the radio will receive
clear and private signals. The PVT status flag in
the display turns on when the private mode is
enabled. If the selected group or channel is pro-
grammed for autoselect capability, the mode may
be toggled between private and clear using the
@
- PVT keys (shifted
P
). Radios pro-
grammed for forced private operation do not allow
a change of the transmit mode; the PVT key does
not function.
If a forced private radio loses its keys, it will
only be able to transmit on designated clear and
digital groups/channels/special calls. It will not be
a bl e t o t ran smi t o n designated private
groups/channels/special calls.
