Power source - no signal but connected

Hello, I have connection problems, a connection failed message appears then disappears.
So I can never get into the race.
It’s a real problem how can I solve it. Thank you.

Can you give us more details about the device you are connecting to?

If you are connecting Bluetooth, I get that message when the device is connected to another use. Make sure the TACX has been disconnected from all other possibilities (phone, tablet, ATV, etc)…

If Ant+…I have no idea…try another USB port, power cycle, normal trouble shooting actions.
