Last couple weeks, every time I fire up RC, it beeps continually, indicating it needs calibration.  go thru teh process but the 'Finish' button never highlights...which means the process never completes 100%.  

All firmware is up-to-date on both RC's, i2 and all batteries. Getting monotonous and frustrating. Also, if clients are nearby, they usually asking 'VERY quickly' what's wrong...  

Anyone seen this issue?  THANKS!!!

Hi, we do apologize for the troubles that it may cause. If the troubleshooting steps were exhausted, however, the problem would persist, I'm afraid that the remote controller wouldn't work properly and may cause incident during your flight. We would recommend contacting our support for further check. You may refer to the link below.
