enable is checked).
When the UAV enables RTL mode, if the current height of UAV is smaller than the
minimum RTL height, UAV will first rise to the RTL mode height and then implement
the RTL operation; or else, it will return at the current height.
Note: after the geographical rail is enabled, there will be prompt and the operation will
be limited if the GUIDED cruise or the flight with designated point goes beyond the rail.
4. Instructions for Flying
4.1. Check up before flying
(1) Check the battery of ground station, and the battery of UAV and the remote. The
normal voltage of battery is "21.6V-25.2V". It is recommended that before each flight,
please get the fully-charged "25.2V battery"; when battery is lower than "21.6V", it is
recommended to stop the flight and remove the battery for charging.
(2) before the flight, make sure that the stands of UAV are properly installed (fastened),
and ensure that six arms are properly installed, and make sure that the numbers of arm
is identical with the number of main body (meanwhile, the paddle on the arm of No.
1.3.5 is reserved paddle, and the paddle of No. 2, 4 and 6 is positive paddle), and
finally make sure that the fixing airscrew is firmly fixed.
(3) Start the remote of UAV (you need to start the remote before powering on), you
need to make sure, that the remote is properly matched with and connected to your
UAV, and make sure that the parameters of remote are properly set.
(4) There are two lines in the front of battery of aircraft, respectively, with red for the
positive, black for the negative; when powered on, you need to connect the negative
electrode first and then positive electrode, and you need to finish the operation as
quickly as possible to avoid frequent touch. This may result in joint oxidation and
reduce aircraft stability.
(5) Put battery into the battery compartment with a fixed strap, close the battery
compartment cover, and make sure the battery compartment is locked. Check out the
status through ground observation station. It is recommended to fly when HDOP value
is less than or equal to 1.

IRCRAFT CALIBRATION
Before flying the drone, the magnetic compass calibration must be performed,
otherwise it might cause
the system doesn’t work properly, and this may affect flight
safety. Magnetic compass is susceptible to interference from other electronic devices,
