So how were you able to navigate that return process with TE, because this is their response to my request when submitting a support ticket directly to them-
‘Thank you for contacting us!
the clicking sound that you hear is due to the moving parts inside the bearing mechanism facilitating the rotation of the wheel. as the TP–7 is a mechanical device, there will always be a degree of mechanical noise picked up when recording with the internal mic.
if you want, there is the option to turn the motor off (enter the menu>motor>spin the wheel to X).
if you feel like the sounds are above what is normal (as described above), please feel free to send us a video of your device and we can assess further
