Clear Modes
Aegis clear and Voice Guard clear modes are identical voice modes in which
the radio transmits and receives only clear (analog) voice signals. These ana-
log signals are non-digitized and non-encrypted. Clear mode transmissions
can be easily monitored by unauthorized persons. Groups or channels pro-
grammed for clear operation cannot transmit or receive Aegis digital or pri-
vate messages.
AEGIS Digital Mode
Aegis digital mode allows the radio to transmit and receive digitized voice
signals. Aegis digital signals provide improved weak signal performance and
they cannot be easily monitored with a standard receiver. Groups and chan-
Conventional Aegis or encrypted channels require Channel Guard on
the channel to operate correctly.
