AEGIS AND VOICE GUARD OPERATION
Voice Modes
Each system (trunked or conventional) in the radio is
programmed for either Aegis or Voice Guard communi-
cations. Aegis programmed systems have three (3) dif-
ferent 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 system 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.
