Firmware Update Items•The camera Electronic Image Stabilization (EIS) feature is now defaulted to ON.

•A gimbal reset function was added to reset the camera gimbal if it begins to behave
abnormally. This may occur due to environmental factors such as strong winds. In thiscase, press the “Reset Gimbal” button, as shown in Figure 2., to re-initialize the camera
gimbal. This button can be accessed in the advanced camera settings menu
(accessed by pressing the gear icon in the camera settings menu).

•The ability to continuously record video in high-temperature environments wasimproved. When shooting continuously in a high-temperature environment, the"Camera High Temperature " warning message will no longer be displayed but thecamera may become quite hot.

•The initial configuration of the video source is now automatic. No manual configurationis required.

•The gimbal tilt (pitch angle) speed is now automatically adjusted depending on thecamera zoom factor. At high magnification, the gimbal tilt speed is automaticallyslowed down to make it easier to adjust the camera view.

•The speed limit for flight in position (POS) mode when GPS is not reliable has been
increased from 0.8 m/s (1.8 mph) to 2.0 m/s (4.5 mph).
