Profile
A complete DJI LIGHTBIRDGE comprises of an air system and a ground system. It is a high definition video
transmitter, flight controller On Screen Display (OSD) and supports remote controls using the 2.4GHz
frequency band. As it is small, power efficient and highly sensitive, the DJI LIGHTBRIDGE can be used for
many activities. The air system must be attached to the aircraft and the ground system must be connected to a
monitor to display the video and flight controller OSD information.
When the DJI LIGHTBRIDGE transmits the video and flight controller OSD information, the air system is the
transmitter while the ground is the receiver. The air system pulls video from the camera and OSD information
from the flight controller then modulates it and transmits to the ground system. The ground system then
receives the information, demodulates it and sends it to a monitor or mobile device. The DJI LIGHTBRIDGE
App, available for smart devices is required for an ideal viewing experience.
When the DJI LIGHTBRIDGE transmits the remote control signal the ground system works as a transmitter
while the air system works as a receiver. The ground system can connect to two remote controls, one for
aircraft and the other for gimbal control. A DJI flight control system with DBUS port is required as the built in
receiver only supports the DJI DBUS protocol.
* 2.4GHz remote controls must be connected correctly to the ground system. Incorrect connection may lead to
malfunction due to interference.

Caution
Aircraft in flight can cause serious damage or injury. Please fly safely at all times.
Assembly Cautions
(1) Install antennas before powering on ground system or air system.
(2) Point air system antennas downward when in use, do not twist or bend antennas. Avoid obstructing
antennas to ensure transmission quality.
(3) Keep both ends of air system antennas as further as possible to achieve optimal transmission
performance. In addition, keep these antennas away from metals.
(4) Use only DJI approved antennas and installed them correctly. Other antennas are incompatible.
(5) Only 2.4GHz remote control can be connected to ground system of DJI LIGHTBRIDGE. Chose the
remote control with PPM trainer output.
(6) 2.4GHz remote controls must be connected to ground system for aircraft and gimbal control through
training ports. RF functions must be switched off.
(7) Do not create shorts or open circuits when soldering.
(8) Do not rotate gimbal if connected to camera HDMI port using DJI AV gimbal. This will cause gimbal
or HDMI cable damage.
(9) Disconnect HDMI cable from the camera when powering on the DJI non-HD gimbal. Failure to do so
might damage HDMI cable.
(10) Keep HDMI cable away from on-board GPS module.
(11) Do not modify DJI LIGHTBRIDGE.
Usage Cautions
(1) Check that all connections are correct and firm before every use.
(2) Check ground system battery capacity before every use. If the battery capacity is lower than 25%,
charge ground system. If ground system powers off, the air system will enter failsafe mode.
(3) Check environment before every use to ensure no 2.4GHz device interference (e.g. other 2.4GHz
remote controls, Phantom 2 Visions).
(4) Check remote control channels using DJI LIGHTBRIDGE Assistant before every use to ensure a good
connection and normal functionality.
(5) The air system built-in receiver will go into failsafe mode if the remote control and ground system are
disconnected during use.
(6) Turn smart device sound volume to maximum to hear alarms more clearly, e.g. bad remote control
signal and low aircraft battery capacity.

(7) Flight control system OSD work best when more than 6 GPS satellites are searched.
(8) Land slowly (≤1.5m/s) with the Phantom 2, as rapid landings can cause it to spin.
Others
(1) We strongly recommend using as many DJI parts as possible.
(2) If you have problems you cannot resolve, please contact your dealer or DJI customer service.
