Operator`s manual

CLEAR MODES
In clear mode the radio transmits and receives only 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 Aegis
digital messages.
AEGIS DIGITAL MODE
Aegis digital mode allows the radio to transmit and received 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.
Message trunked group calls and individual calls will be answered back
in the mode in which 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
during the call back time.
3. When using the "call back" feature to respond to an I-Call the call
will be transmitted in the mode in which it was received.
Scanned Group Calls
Receiving a scanned group call is the same as receiving a selected group
call. During the scan hang time, if the radio was programmed for autoselect,
it will transmit back in the same mode in which the call was received. For
example, if a clear group is entered in the scan list, it will only receive clear
calls. If the same group was available in digital and entered in the scan list, it
can receive clear and digital calls, provided autoselect was programmed in the
radio. The user can select transmitting on the scanned or selected group. If a
Conventional Aegis requires Channel Guard on the channel to operate
correctly.
