Battery Issues
7- Check battery for water damage, signs of disassembly, if the buckles are loose,
and/or the contact pins are misshapen
– If the battery is water damaged or disassembled then it needs to be
replaced
– If the buckles are loose then the battery may fall out of the battery
compartment
– If contact pins are misshapen then the batter cannot connect to the aircraft
normally
– Insert the battery into the aircraft to check if the battery level is normal
– After pressing the buttons there is no response and the LEDs do not light
up. It is possible that the battery has entered the shutdown low battery
level protection mode. Charge battery on hub to resolve.
– After pressing the buttons, there is no response. Battery may be in
firmware update mode due to an update failure. To resolve mount battery
to aircraft and update firmware
– After pressing the power button, the aircraft can be powered on but the
aircraft soon powers off. The battery needs to be charged
– The battery can be charged normally
– If there is no response after pressing the button and the LED lights do not
light up after being mounted into the charger it is most likely that it is in
Permanent fail mode
– The aircraft with an inserted battery can be powered on normally but the
battery cannot be charged normally after inserting it into the two way
charging hub and the LEDs blink in a specific pattern. The protection
function is triggered and charging is forbidden
– The aircraft can be powered on normally but the battery cannot be
charged normally. The battery charging circuit is damaged
– The battery can be charged normally but the charging hub and aircraft
battery level indicators blink one by one. The update failed and the Battery
is in FU mode
– The app shows that the battery is normal
– Check if the voltage difference is large, communication failure,
authentication failure or the battery is poorly mounted
– If the battery cycle is over 200, old age may be the cause.
8- The flight test in low altitude is normal
– Check voltage difference
Remote Controller Issues
– Visual inspection
– Connect the remote controller to the aircraft to check if the remote controller’s
buttons are normal
– Determine the corresponding damaged button,control stick, or button
board
– Link the remote controller to the aircraft and check if the image transmission on

– Pictures are clear
10- Camera is defective
– dark dots or dots with abnormal colors on the pictures.
– The issue may be due to image noise or dirt on the camera
– If issue persists camera is defective
Camera error after replacement
– Download camera data
– Attempt to calibrate
– Check connection points
Rotation issue
– DJI Fly gimbal calibration
– If there is an issue then there may be something wrong with the axis arm
Altitude Detection Error
1. 2. 3. 4. Perform a link test to see if the infrared distance sensor and downward vision
system is functioning normally
Check whether there is dirt on the downward vision system. If yes, clean off the
dirt
Power on the aircraft, and check if the infrared distance sensor indicator on the
right side of the aircraft light up. If not, the infrared distance sensor is
malfunctioning.
Perform a flight test. If the aircraft still fails to detect the current altitude, it is
possible that the downward monocular vision module or the core board is
damaged.
Front LED Not Lighting Up
1. 2. Disassemble the aircraft, and check if the front LED is damaged. If the aircraft
cannot be disassembled, check if the ESC board can drive the motor normally. If
yes, the front LED is damaged.
Check whether the front LED is connected to the ESC board normally. If not,
reconnect it and see if the error still exists
113. Connect a normal front LED to the ESC board. If the LED does not light up, the
ESC board is damaged.
Aircraft Not Making Sounds when Powered on
(The startup sounds are emitted by the motors.)
1. 2. Connect each motor to the ESC board, and power on the aircraft to see if the
motor can emit sounds normally. If not, the motor is damaged.
Replace the ESC board and test again. If this issue is fixed after the
replacement, the ESC board is damaged.
Bluetooth/WIFI issues
1. 2. 3. Switch the aircraft to Wi-Fi mode, and check if the aircraft status indicator can
blink correctly. If not, it is possible that the core board is damaged.
Connect the aircraft to the mobile phone, and check if the connection is
successful on DJI Fly. If the Wi-Fi signals are weak, it is possible that the
antennas are defective. If the Wi-Fi signals are totally unavailable, the core board
may be damaged
Check if the aircraft can be controlled normally (supported in future). If not, it is
possible that there is a firmware failure or core board hardware error.
