Conventional Aegis or encrypted channels require Channel Guard on the
channel to operate correctly.
Clear Modes
Aegis clear, ProVoice clear and Voice Guard clear modes are identical
voice modes in which the radio transmits and receives only clear (analog)
voice signals. These analog signals are non-digitized and non-encrypted.
Clear mode transmissions can be easily monitored by unauthorized persons.
Groups or channels programmed for clear operation cannot transmit or
receive unencrypted digital or private messages.
AEGIS/ProVoice Digital Mode
Aegis/ProVoice digital mode allows the radio to transmit and receive
digitized voice signals. These digital signals provide improved weak signal
performance and they cannot be easily monitored with a standard receiver.
Groups and channels programmed for Aegis or ProVoice digital operation
transmit only digital signals. Private calls cannot be received or transmitted
when the radio is in the Aegis or ProVoice digital mode because the radio
does not know the cryptographic key used.
