Storage and Transportation
There are safety requirements for the storage and transportation of the Intelligent Flight Batteries.
Please strictly follow these Intelligent Flight Battery Safety Guidelines.
Firmware Updates
To optimize your experience, it is recommended to keep the rmware of the aircraft and remote controller
up to date before each ight. Refer to the User Manual for instructions on running a rmware update.
If the rmware update fails, restart the device and retry. If the problem persists, please contact DJI
Support.
Inspection and Maintenance
Routine inspection before and after operations or regular maintenance can greatly improve the
aircraft’s reliability, reduce potential safety hazards, and extend its service life.
Routine Inspection
It is recommended to check the following before each ight.
Checklist When Powered Off
Type Essentials
1. Visually inspect and use your ngers to feel the propellers, frame arms, arm
junctions, and landing gears to check if they are in good condition. If there are
any cracks or damage, replace the component immediately. ※
Structure
Motors
Batteries
2. The screws for all the connection structures are securely tightened, especially
those for the arm junctions and battery locker.
3. The waterproof rubber port covers are in place. If not, water may enter the
aircraft body which will cause short circuit.
4. There is no blockage in the intake vent of the upper cooling fan.
1. The propellers are not visibly deformed, damaged, aged or softened. If they
are, replace the propellers immediately. If there are any foreign objects on the
propellers, clear them before use. ※
2. Rotate the motors manually to check if they are rmly installed without a gap
between the motors and the motor base and the motors rotate smoothly without
noise.
3. Propellers are mounted correctly. CCW propellers should be on motors 1 and 3,
and CW propellers should be on motors 2 and 4. (The front-facing propeller on the
right is motor 1, with motor 2, 3, and 4 arranged in a counter-clockwise order.)
4. Refer to the propulsion system section in the Regular Maintenance Items.
1. There is no foreign object in the battery ports on the aircraft and the ports are not
misshapen.
2. The battery locker is secure and will not come loose during ight.
3. The battery shell has no visible damage. If it does, DO NOT use the battery for
ight.
