ok i dont understand why its not working i calibrated the unit and still get a flashing (!) and know message pops up letting me know what the problem is. im running the current firmware on naza and window 8. can someone pleas epiont me to the right direction please.

Hi,

What's the message of flashing(!) ? Could you elaborate it?
How's the IOC setting/response in Naza assistant software?

Cheers

maybe there are so many iron things near the phantom keep calibrate until the phantom flash the yellow lights

i found out what it was. it was a bad compass wire thanks guys.
