CONTINUOUSWAVE

Hi all. I have a Lowrance HDS-5x, a NMEA 2000 network, and have just added a Sonic Hub [Marine Audio Server]. I have enabled audio and have the audio tool bar across the bottom of the HDS-5x screen. How do I control the [Sonic Hub]? I have not seen a new options in any menu. Any help greatly appreciated. My first-ever post here, and really like the info here.

Today I received a reply to my email on this matter from Navico: "Hold down the PAGES key till the Sonic Hub toll [scroll?] bar is highlighted; then you will be able to access the Sonic Hub menus". I have asked where this info is available, as I have read the manual a few times and am still not able to find it in there.
