• When flying over water, avoid the drone dropping or crash into the water from a high
altitude as this could cause major damage to the drone.
• Do not expose the drone & battery to direct sunlight for long periods 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 controller, 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, poor radio signal, or weak Earth magnetic field.
• If the drone Appears to be affected by magnetic interference, try the following
remedies.
• Re-calibrate both the compass and accelerometer on the SplashDrone 4.
• 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 SplashDrone 4. Following the re-calibration, please test the
drone again.
• If the problem persists, please contact SwellPro or your local dealer for further
troubleshooting and solutions.

indicates that the control inputs are not centered when the joysticks are in their neutral
position.
To calibrate the joysticks, refer to the SwellProTools firmware update instructions.
It is necessary to calibrate the remote stick when changing the throttle mode.
