Teamspeak 3 Setup On Network Radio (INRICO T320)

Hi all. I have just purchased a new Network Radio (Inrico T320) and installed Teamspeak 3. I sign into the IRN Network and I am unable to setup the Audio. I use the Echo facility and i can hear myself but even with the volume of the radio on full, i can hardly hear myself.

Any assistance would be appreciated.
Thanks
