I just received a brand new XRX. At my first fligt, I see a Traffic Alert on the Traffic Screen (The screen flash Black) but I ear NO SOUND from the In-Cabin audio (the Headset and the connector furnished with the kit was not connected, and the XRX was not connected to a GPS). When I test the sound on ground I just ear a beep, but you can not eard this beep in flight with your headset.

In the manual I read on page 55 "XRX incorporates an internal audible tone Generator ...... This tone is hight-pitched and at a volume that can be herd over the noise level in a standad cockpit, similar to a stall warning horn" How can I test this sound on ground ? I check The switch 6 from group A and the Swxitch Is On

Thank you from your help.

Bad news, In my club, a friend also own a XRX since less then a year, which crashed yesterday...

Sorry for my poor english I usualy speak french

I received the answer via e-mail, thank you.
