Answer
The ARUA-10 cannot be used with KNS
(remote operation over a network).
When operating the ARUA-10, audio
reception from the transceiver is played
over the computer speakers. If you want
to stop audio reception, stop the ARUA-10
operation.
Also, when not using the TS-990S, we
recommend you disconnect the USB
cable from the computer.
