The manual describes inspection checks but does not provide repair steps. Arrange qualified service for abnormal or damaged hardware rather than treating this checklist as a repair procedure.[1]
Follow these steps
Check for obstructions
Look for branches, bird nests or other objects blocking the device. Remove obstructions promptly so they do not affect heat dissipation or signal transmission and reception.[1]
Inspect the mounting hardware and safety wires
Check expansion bolts and nuts for looseness, corrosion or detachment. Inspect anti-fall steel wire ropes and their connections for corrosion or looseness. The manual says to replace parts promptly when abnormalities are found.[1]
Check signal coverage
DJI recommends using an aircraft to inspect signal coverage around the device and confirm signal quality is normal.[1]
