Aegis clear and Voice Guard clear modes are identical voice
modes in which the radio transmits and receives only clear (ana-
log) voice signals. These analog signals are non-digitized and
non-encrypted. Clear mode transmissions can be easily moni-
tored by unauthorized persons. Groups or channels pro-
grammed for clear operation cannot transmit or receive Aegis
digital or private messages.

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 channels programmed for
Aegis digital operation transmit only digital signals. Private calls
cannot be received or transmitted when the radio is in the Aegis
digital mode because the radio does not know the cryptographic
key used. Message trunked group calls and individual calls will be
answered back in the mode they were received, assuming the call
or hangtime is still active. Individual, phone, all and emergency
calls will be transmitted clear if digital mode is disabled or inop-
erative.
