AEGIS AND VOICE GUARD OPERATION

VOICE MODES

Each system (trunked or conventional) in the radio is programmed for either
Aegis or Voice Guard communications. Aegis programmed systems have
three (3) different voice modes: clear (analog), digital and private. Voice
Guard systems have two (2) voice modes: clear (analog) and private. The
voice modes are programmed on a per-group basis within each trunked sys-
tem and on a per-channel basis within each conventional system. A radio
must be equipped with the encrypt/decrypt option before it will operate in
Aegis or Voice Guard modes.
