Check if the batteries in the Controller and unit are fully charged? (Follow Recommended charging times in charging manual and walk customer through the proper light sequencing for their unit).
Try turning on the unit and then controller. After controller is on, try syncing the drone by moving the left joystick up (you hear a beep) and then down (you hear another beep). From blinking lights, the lights on the drone should become solid. Once the lights are solid the drone is synced.
If this does not solve the issue, please contact customer service.
