## Firmware & Software Upgrade Firmware Upgrade Follow the procedures below to upgrade the H4-3D’s firmware. Failure to follow these instructions carefully may damage the gimbal. 1. Ensure your computer has access to the internet. 2. Close all other applications (including anti-virus programs or firewalls) before upgrading the

firmware. 3. Make sure the power supply is securely connected. DO NOT unplug the power supply before

the upgrade is complete. 4. Connect the GCU to your PC through a Micro-USB cable. DO NOT disconnect the cable until

the firmware upgrade is complete. 5. Launch the PC Assistant and wait until the connection is establ ished. 6. Select “Upgrade” Main Control, IMU and CMU. 7. The DJI server will check the current firmware version. 8. If a newer firmware is detected, the PC Assistant will download and upgrade the firmware

automatically. 9. Wait until the upgrade completes. 10. Click “OK” and power cycle (turn off, then turn on again) the system to finish the upgrade

process.

CMU stands for “Camera Multi Unit”, which is the management mod ule for the camera. To eliminate interference from the main controller, DJI recommends you disconnect the CAN-Bus cable between the GCU and main controller before you up grade the firmware. Double check your set parameters once you have finished upgradin g the firmware. Repeat the above steps if the DJI server is experiencing heavy traffic or the firmware upgrade fails. 

### Software Upgrade Click Info Software Info. If the latest version is newer than your current version, please upgrade your software. Obtain your gimbal’s serial number (SN) by clicking the “Info” “SN”. The serial number is a 32 digit authorization code that is used to activate the gimbal. This number is set at the time of manufacture, before shipment. You may be prompted to fill in a new SN if you purchase a new feature. If you fill an invalid SN more than 30 times, the gimbal will be locked and you will have to contact our customer support to unlock the gimbal.Configuration

# Test Flight Pre-flight Checklist For safety reasons, check all of the following items before eac h flight: 1. The gimbal is firmly installed onto the aircraft, and the camera is mounted correctly. Make sure

the camera is aligned facing the nose of the aircraft. 2. All cables are firmly and correctly connected. 3. The gimbal video signal cable is firmly soldered in place. 4. The wireless video transmission module is connected to the GCU before powering on the system. 5. The remote control is properly configured. 6. The camera is correctly connected to the gimbal. 7. The GCU and flight control system are correctly connected. 8. The flight control firmware is updated to the latest version. 

## Gimbal Test

1. Ensure all batteries are fully charged. 2. Turn on the remote control. 3. Power on your camera, then power on the gimbal and wait until g imbal’s self-test completes. 4. The camera lens should be pointing in the same direction as the aircraft nose. All three axes of

gimbal should be in the positions depicted in the diagram above. 5. Toggle the tilt control switch on your transmitter and make sur e it is working properly. Check that

the gimbal moves in the correct direction when the switch is to ggled. If not, check your settings. 6. When the test is complete, power off the gimbal first, then the camera.
If the gimbal is not working properly, refer to Troubleshooting (P19) for solutions. Place the aircraft on a flat surface during the test. If you choose to hold the aircraft while testing, do not tilt the aircraft more than 35°. Do not land an aircraft with a powered-on gimbal on uneven terrain (such as a grass lawn or rocky surface). In such conditions there may be objects that will block the motion of the gimbal and force it into hibernation mode. Hibernation mode offers protection for the gimbal. When a camera is not mounted on the gimbal, it will default to hibernation mode. During hibernation, the gimbal does not respond to any commands from the transmitter. The gimbal resumes normal operation once a camera is mounted. The gimbal enters hibernation mode when it detects external objects blocking its range of motion. Once such objects are no longer detected, the gimbal wi ll resume normal operation. Use of a separate battery pack to test the gimbal is suggested before powering on the flight controller, gimbal, OSD, FPV gears, etc.Test Flight© 2015 DJI. All Rights Reserved.

# Appendix Troubleshooting

Problem Cause Solution

Gimbal keeps drifting after initialization. 1. The transmitter trims value is beyond the acceptable limit. 2. The GCU is disconnected from the

flight control system. 3. The gimbal is not mounted correctly. 

### 1. Adju st the transmitter trims value. 2. Connect the GCU and flight control

system. 3. Ensure the gimbal is mounted so it

is parallel with the aircraft, and the camera is 

### pointing towards the nose. The gimbal axes are not level. Factory calibration error. Contact your local dealer or DJI customer service for assistance. Unable to determine gimbal orientation. BVR (beyond visual range) flight. Use a wireless video transmission module. 

## Settings When Using the A2 Flight Control System Users should configure the H4-3D’s pitch control in the A2 assistant when using the A2 Flight Control System. Map the H4-3D to two channels on the transmitter as shown in the following diagram.
