Dock Cover
The internal video transmission antennas and status indicators are located on the dock cover.
The Dock Cover Propeller Bumpers on the dock cover are used for folding the aircraft propellers
when closing the dock cover. The heating strips on the dock cover seam can automatically heat
the dock cover to prevent the seam from freezing.
• Make sure the internal video transmission antennas are not blocked by snow, ice, or
any foreign matter.
• The dock cover heating strips can only prevent the dock cover seam from freezing.
Make sure to clean any snow or ice on the dock cover.
• Regularly check if the propeller bumpers are in good condition. Replace any worn or
damaged parts when necessary.
Opening and Closing the Dock Cover
When performing remote debugging, the dock cover can be opened or closed using DJI
FlightHub 2 or DJI Pilot 2 to check the aircraft status and the component status inside the dock.
The dock cover can also be controlled using either the open or close button in the electrical
cabinet. Make sure the emergency stop button is released before opening the dock cover. If the
emergency stop button is not released, pull out or rotate clockwise to release the emergency
stop button.
• Keep a safe distance from the dock cover to avoid injury when opening or closing the
dock cover. Press the emergency stop button if necessary.
• DO NOT press or place heavy objects on the dock cover after it is opened.
