vide improved weak signal performance and they cannot
be easily monitored with a standard receiver. Groups and
channels programmed for Aegis digital operation trans-
mit 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 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 during 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.
