DJM-T1 timecode problem

I am having a problem with with using vinyl timecode.

When I play it fails to calibrate, and only the cd option next to the play button is orange not the vinyl one.

I have set it it in the app repeatedly to phono timecode and updated to the latest firmware. I'm running on Windows.

Even though it fails to calibrate, it still plays with the cd light orange but at a weird tempo nowhere near correct at 0%.

Have I missed something really obvious?

Thanks
