If your gimbal beeps several several times (approximately 13 times) whenever you restart the system, this could be a Calibration Mode. If it continues to beep non-stop, this most likely is a Low Battery Warning (see here).
When your Gimbal is going through a Calibration process it is important to have the entire gimbal level, hold the camera level, and also hold the gimbal frame square and centered. Once it is done calibrating, the gimbal should hold the camera position. If you allow the calibration to process while the gimbal or camera is not level, the calibration will be set to whatever position you allowed it to process.
We suggest disabling this feature and to only perform Calibration Manually when needed. To disable the Calibration process each time you restart, connect to the software and select the option 'Skip Calibration on Startup' under the Basic Tab.
Make sure to click on the Write Button to save your settings. Now each time you startup, the Gimbal will boot up immediately.
