• The Return Home function can be used to reorient the drone towards the Home Point. By activating
the Return Home function, the drone will rise to the return altitude (20m) and then turn towards the
Home Point before starting its return.
• If any obstacles are in the flight path of the drone during a Return Home process, control should be
regained by turning off the Return Home function.
• If you inadvertently crash your drone, lock the motors to prevent damage to the motors and propellers.
• Do not attempt to touch the motors, until the motors have stopped rotating.
• When landing from water, avoid high-speed or abusive landings to avoid damaging the drone.
• When flying over water, avoid allowing the drone to drop or crash into the water from a high altitude as
this could cause major damage to the drone.
• Don't expose the drone & battery to direct sunlight for sustained periods of time as this can raise the
internal temperature of the drone to well above the operating temperature range.
• If the drone does not appear to be responding to the Remote control as usual, switch the drone to ATTI
flight mode and fly the drone to a safe landing location
• The possible causes for the instability or loss of control of the drone could be poor GPS signal or radio
or magnetic interference or poor calibration practices.
• If the drone appears to be affected by magnetic interference, try the following remedies.
• Re-calibrate both the compass and accelerometer on the SD4.
• After completing the calibration, arm the drone motors to fly in GPS mode to verify whether this
phenomenon has been eliminated.
• If the abnormality remains the same, please re-locate to another place at least 5KM away and re-
calibrate the SD4. Following the re-calibration, please test the drone again.
• If the problem persists, please contact SwellPro or your local dealer for further trouble-shooting and
solutions.
Maintenance
⚫ Please make sure to double-check the propellers after flight. Distorted or damaged propellers should
be replaced immediately.
⚫ After flying over the sea, sand or water, the SD4 and modules must be thoroughly washed with fresh
water within 2 hours and dried - especially the motors, gimbals and camera.
⚫ It's strongly advised to rinse the drone before any salt crystalizes.
⚫ Motors are best rinsed by removing the propellers and immersing the motors one at a time into a
bucket of warm fresh water and arming the drone in ATTI flight mode so the motors spin underwater.
⚫ In the event of the SD4 not being used for a long time, please store the drone and the batteries in a
dry, and ventilated environment at 20°C~28°C.
Flight Safety
• Please make sure you have a comprehensive understanding of the SD4 and all the necessary
measures required to implement a successful return home function in the event of an
emergency.
• Please be well prepared before each flight, avoid any violent or excessive operations.
• Please maintain strict compliance with the local laws, any flying in NO-FLY ZONES is
prohibited.
• Any illegal & improper use or operation of this product is prohibited.
