Dji Agras App; Product Care; Storage And Transportation - DJI AGRAS T20 Manual Del Usuario

2. 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.
3. The obstacle detection range of the radar module is 360° in the
horizontal direction and ±15° in the vertical direction, as shown in
the figure below, and the detection distance is 1.5 - 30 m. Note that
the aircraft cannot sense obstacles that are not within the detection
range. Fly with caution. For the four gray areas with an angle
approx. 10° for each area in the figure, the detection performance
of the radar module may be reduced, due to the obstruction of
the frame arms and landing gear. Fly with caution. The effective
detection distance varies depending on the size and material of the
obstacle. For example, when sensing strong reflective objects such
as buildings that have a radar cross section (RCS) of more than
-5 dBsm, the effective detection distance is around 20 m. When
sensing objects such as power lines that have a RCS of -10 dBsm,
the distance is around 15 m. When sensing objects such as dry tree
branches that have a RCS of -15 dBsm, the distance is around 10 m.
Obstacle sensing may malfunction or be invalid in areas outside of
the effective detection distance.
4. When mounting the radar module, make sure the arrow mark is
pointing towards the aircraft front.

1. Comply with local radio transmission laws and regulations.
2. The radar module can only function properly in flat landscapes. It
cannot function in sloping landscapes with inclinations more than 10°
or in landscapes with sudden changes in elevation.
3. The sensitivity of the radar module may be reduced when operating
several aircraft within a short distance. Operate with caution.
4. Before use, make sure that the radar module is clean and the outer
protective cover is not cracked, chipped, sunken, or misshapen.
5. The obstacle avoidance functions are disabled in Attitude mode.
6. Obstacle avoidance is adversely affected due to the obstruction of
the aircraft body when aircraft pitch exceeds 15°. Slow down and fly
with caution.
7. The radar module enables the aircraft to maintain a fixed distance
from vegetation only within its working range. Observe the aircraft's
distance from vegetation at all times.
8. 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.
9. Operate with extra caution when flying 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.

10. DO NOT attempt to disassemble any part of the radar module that
has already been mounted prior to shipping.
11. The radar module is a precision instrument. DO NOT squeeze, tap,
or hit the radar module.
12. Land the aircraft on flat ground to avoid damage to the radar
module from raised objects.
Firmware
To avoid component malfunction, serious injury, and property
damage, observe the following rule:
1. Keep people and animals at a safe distance during any firmware
update, system calibration, and parameter setting procedures.
1. For safety, always update to the latest firmware version.
2. Only use official DJI firmware.
3. Make sure to update the remote controller's firmware to the latest
version after you update the aircraft's firmware.
10°
4. The remote controller may become unlinked from the aircraft after
updating. Re-link the remote controller and aircraft.
5. Make sure to check all connections and remove the propellers from
the motors before performing the firmware update.

DJI Agras App

1. Make sure to fully charge the remote controller batteries before
10°
launching the DJI Agras App.
2. Read all safety tips, warning messages, and disclaimers carefully.
Be familiar with the related regulations in your area. You are solely
responsible for being aware of all relevant regulations and flying in a
way that is compliant. Make sure to pay close attention in the following
situations:
a. Using the auto-take off and auto-landing features.
b. Setting the altitude beyond the default limit.
3. Land your aircraft immediately if a prompt appears in the app.
4. Examine and check all warning messages on the aircraft status list
displayed in the app prior to each flight.
5. Cache the map data of the area where you intend to fly the aircraft by
connecting to the internet before each flight.
4G Dongle
1. A dongle and SIM card are required for some product features in the
DJI Agras app and users will bear the cost of these extras.
2. Be sure to use a DJI approved dongle.
3. DJI accepts no liability for accidents caused by the loss of user data
or aircraft malfunctions originating from third party dongles and SIM
cards.
4. Only use SIM cards that are compatible with the dongle.
5. Make sure you mount the dongle and the SIM card correctly.
Otherwise, related functions will not be available.

Product Care

Storage and Transportation

To avoid component malfunction, serious injury, and property
damage, observe the following rules:
1. Small parts, such as cables and straps, are dangerous if swallowed.
Keep all parts out of reach of children and animals.
