User Manual
1. Make sure that you have enabled the obstacle avoidance function of the radar module in the app,
and enable Auto Obstacle Avoidance. Note that Auto Obstacle Avoidance is disabled if Obstacle
Avoidance is disabled.
2. Perform a Route or A-B Route operation. During auto ight, when obstacles are detected, the aircraft
plans a ight route to circumvent the obstacles, and the app shows the real-time obstacle radar map
and planned ight route.
3. The aircraft ies along the planned ight route to circumvent the obstacles. Once the obstacles are
circumvented, the aircraft returns to the operation route.
4. The aircraft hovers in place if a prompt is received in the app indicating that the aircraft failed to
circumvent the obstacle. Users can manually control the aircraft to avoid the obstacles. Refer to
Manual Obstacle Avoidance (p. 22) for more information.
Radar Usage Notice
DO NOT touch or let your hands or body come in contact with the metal parts of the radar
module when powering on or immediately after ight as they may be hot.
In Manual operation mode, users have complete control of the aircraft. Pay attention to the
ying speed and direction when operating. Be aware of the surrounding environment and
avoid the blind spots of the radar module.
Obstacle Avoidance is disabled in Attitude mode.
Obstacle Avoidance is adversely affected due to the obstruction of the aircraft body when
aircraft pitch exceeds 15°. Slow down and y with caution.
When sensing objects that have a vertical inclination of more than 5° such as an inclined line
or inclined utility pole, the sensitivity of the radar module may be reduced. Fly with caution.
The radar module enables the aircraft to maintain a xed distance from vegetation only within
its working range. Observe the aircraft’s distance from vegetation at all times.
Operate with extra caution when ying over inclined surfaces. Recommended maximum
inclination at different aircraft speeds: 10° at 1 m/s, 6° at 3 m/s, and 3° at 5 m/s.
Maintain full control of the aircraft at all times and do not rely on the radar module and DJI
Agras app. Keep the aircraft within VLOS at all times. Use your discretion to operate the
aircraft manually to avoid obstacles.
Comply with local radio transmission laws and regulations.
The radar module can only function properly in at landscapes. It cannot function in sloping
landscapes with inclinations more than 10° or in landscapes with sudden changes in
elevation.
The sensitivity of the radar module may be reduced when operating several aircraft within a
short distance. Operate with caution.
Before use, make sure that the radar module is clean and the outer protective cover is not
cracked, chipped, sunken, or misshapen.
DO NOT attempt to disassemble any part of the radar module that has already been mounted
prior to shipping.
The radar module is a precision instrument. DO NOT squeeze, tap, or hit the radar module.
Land the aircraft on at ground to avoid damage to the radar module from raised objects.
