• Since the video transmission signal may be delayed or lost due
to interference, the wireless transmission settings of the
"Airpeak Flight" app ([Aircraft] — [Sensors/Radio]) should be
changed carefully with a full understanding of the changes.
• After landing, first stop the motors, turn off the aircraft, and
then turn off the remote controller. For safety, be sure to check
that the motors have stopped rotating before turning off the
aircraft and remote controller.
• Do not use mobile device features that may interfere with the
operation of the aircraft, such as answering calls or replying to
emails.
• To execute an emergency motor stop during a flight, tilt the left
and right control sticks of the remote controller either inward
and downward, or outward and downward at the same time.
The aircraft will crash if the motors stop during a flight.
• To turn off the power, do the following:
— Aircraft: Press and hold the  (Power) button for at least 2
sec.
— Remote controller: Press and hold the  (Power) button for
at least 5 sec.
• To force the power off, do the following:
— Aircraft: Remove the battery packs.
— Remote controller: Press and hold the  (Power) button for
at least 10 sec. If this does not turn off the remote controller,
simultaneously press and hold the C2 (Custom 2) button and
the  (Power) button for at least 10 sec.
About the RTH (Return to Home) function
• The RTH (Return to Home) function may be affected by
weather, the surrounding environment, or nearby magnetic
fields.
• The aircraft cannot avoid obstacles if there is not enough
surrounding light during RTH (Return to Home).
• Set the altitude for obstacle avoidance before performing RTH
(Return to Home).
• RTH (Return to Home) does not work when there is an
insufficient GNSS (Global Navigation Satellite System) signal (3
or fewer signal bars in the status bar of the "Airpeak Flight"
app) or no signal is received from the GNSS (Global Navigation
Satellite System).
About the remaining battery level
• If you are notified of low battery, land the aircraft immediately
and safely.
• When the battery level drops below a certain level, a warning is
displayed and the aircraft automatically starts descending to
perform a forced landing. In order to steer the aircraft to an
appropriate landing point while maintaining altitude, operate
the remote controller to perform ascent while the aircraft is
descending.
• If a battery level warning appears on the "Airpeak Flight" app
screen, land the aircraft at the Home Point or a landing point
immediately. If the battery packs run out of battery during
flight, the aircraft may crash onto the ground, including private
property, causing injury or damage to people or animals.
