nels 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 hang time is still active.
Individual, phone, all and emergency calls will be transmitted clear if digital
mode is disabled or inoperative.
1. If receiving an analog message trunked call, the radio will respond in
analog mode during the hang time on the working channel.
2. If receiving an analog I-Call, the radio will respond in analog mode dur-
ing the hang time.
3. When using the "WHC" feature to respond to an I-Call (after the hang
time has expired), the call will be transmitted in the mode defined by the
system mode as programmed for the current system if the ID being
called is not in the I-Call list. If the ID is in the I-Call list, then the call
will be transmitted as defined by the I-Call mode programmed in the list
for that ID.
DTMF
The overdial and hot keypad features for transmitting DTMF tones are not
available while in the Aegis Digital Mode.
