Introduction
DJI Digital FPV System
The DJI Digital FPV System consists of the DJI FPV Air Unit, DJI FPV Goggles, and DJI FPV Remote
Controller, featuring the DJI HD Low Latency FPV Transmission, to provide an integrated video
transmission with high definition and low latency for racing flight. The DJI Digital FPV System supports
a 5.8 GHz digital video signal and 720p 120fps image transmission, with a transmission range of up
to 4 km and a minimum end-to-end latency within 28 ms*. Up to eight fixed channels are supported**,
and the enhanced anti-interference ability greatly improves the smoothness and stability of the
video transmission. The DJI Digital FPV System integrates a camera, video transmission, display
view, and remote control to provide a high-quality racing experience.
Typical Application Scenario
The DJI FPV Air Unit includes the air unit module and camera, which can be mounted on a racing
drone and used with the goggles or a remote controller to transmit video, control signals, and flight
controller information wirelessly.
The DJI FPV Goggles are equipped with a high-performance display and support 810p 120fps HD
display. When used with a racing drone equipped with the air unit, users can enjoy a first-person
view of their aerial experience in real time.
The DJI FPV Remote Controller works with the air unit and goggles, and can be used to control the
aircraft and operate the menu screen of the goggles to set parameters.
* The end-to-end latency is the total time from camera input to screen display. The DJI Digital FPV System can reach its minimum
latency in Low Latency mode (720p 120fps), and achieving maximum transmission distance (FCC) in a wide open area with no
electromagnetic interference. The aircraft will fall if the video or control signal is disconnected. Be careful when flying at low altitudes
and long distances.
** There are up to eight channels for the DJI Digital FPV System depending on the region (FCC: eight, CE/SRRC: four, MIC: three). Each
channel has a bandwidth of 20 MHz. The public channel is 8, which is the default channel when the equipment is powered on. The

When linked to the remote controller, the remote controller can be used to operate the
screen of the goggles.
a) Use the right dial to scroll in the menu screen and press the right dial to confirm.
b) Press the back button to return to the previous menu or exit the current mode.
c) Press the record button to start or stop recording video.
Live view will be temporarily unstable when entering Player or Audience mode as the
transmission system will scan all channels.
The goggles can save the selected channel, so that they will enter the previous channel
when restarted. The saved channel will be scanned before entering, and the goggles will
enter the channel if it is not occupied. Otherwise, the goggles will enter the public channel.
When powering on, the devices enter the public channel by default to link. Note that
before entering the saved channel, the goggles will temporarily indicate that they are in
the public channel.
In Player mode, if an occupied channel is selected, the goggles currently occupying that
channel will receive a warning prompt that another pair of goggles will occupy the channel
and a countdown begins. The goggles currently occupying the channel must land the
aircraft as soon as possible, as it will be set to the public channel after the countdown
finishes. Once the countdown has finished, the new goggles will occupy the channel.
To avoid potential interference, it is not recommended to select an occupied channel. Any
interference may affect image stabilization or even result in disconnection.
9. Air Unit microSD Card Status
Shows whether or not a microSD card is inserted in the air unit and the remaining capacity. A
flashing icon will appear when recording.
10. Menu Bar

menu bar.
a) Player
Shows the occupancy of each channel. The red

means occupied. You can select a
vacant player channel. The icon will turn to a green
RACING
if a channel is successfully entered.
The public channel is the yellow
PUBLIC
. Note the public channel is easily prone to interference
from other devices on this channel. Change to a vacant channel.
b) Audience
Shows whether each channel is used by a player or not. The blue
means that there
is a player using this channel. You can select the channel to see the camera view as a
spectator.
c) Playback
Shows the videos in the specified directory of the microSD card. Select a video to play.
d) Settings
Adjust the display of the video transmission, set the parameters for the recording, the flight
controller, the camera on the air unit, and more.

Video Recording
Make sure the DJI Digital FPV System is connected with the racing drone, and both the air unit and
goggles have microSD cards inserted. Once the motors are started, the air unit and the goggles will
start recording based on the recording settings. The recording will stop when the motors stop.
The recording will automatically stop when the following occurs.
Air Unit:
1. The storage mode is set to “Stop when Full” and the microSD card is full, or an error occurs
during recording.
2. The temperature of the air unit is too high and enters low-power mode.
Goggles:
1. The storage mode is set to “Stop when Full” and the microSD card is full, or an error occurs
during recording.
2. The transmission is disconnected, or the transmission signal is lost.
3. The live view source is changed, such as switching between Player to Audience mode or
changing a channel in Audience mode.
4. Exit live view, such as entering the RC setting or AV-IN.
5. The temperature of the air unit is too high and enters low-power mode.
Powering off the device or removing the microSD card during recording will result in a
corrupted video file, which cannot be played. Insert the microSD card into the device again,
power on, and the device will attempt to recover the corrupted video file automatically.

Maintenance
DJI FPV Goggles
Cleaning
Make sure to disconnect the goggles from the power outlet before cleaning and make sure that
there are no cables connected.
Clean the surface of the goggles with a soft, dry clean cloth. To clean the foam padding, moisten
the cloth with clean water, and wipe the foam padding.
Replacing the Foam Padding
The foam padding is attached to the goggles with Velcro. When replacing the foam padding, peel
it gradually from the left or right side. Align the new foam padding with the goggles and then press
the foam padding down so it is securely attached.
Maintenance of Lenses
Use a cleaning cloth to wipe the lenses gently.
1. Moisten the cleaning cloth with alcohol or a lens cleaner.
2. Wipe in a circular motion from the center to the outer edges of the lenses.
DO NOT clean the foam padding with alcohol.
The lenses are delicate. Clean them gently. DO NOT scratch them as this will damage the
overall viewing experience.
Store the goggles in a dry room at room temperature to avoid damage to the lenses from
high temperature and humid environments.
