Precaution
⚫The GC3-S is a piece of precision electronics with corrosion-resistant materials
which allow for use in harsh marine environments. As with any marine equipment,
trouble-free and lasting operations depend on proper attention and maintenance of
the equipment.
⚫When taking off or landing, slowly proceed to avoid damage to the gimbal camera
which can cause by the huge impact when contacting the surface at high speeds.
Drop or crash directly into the water from above will result in significant damage to
the drone and the gimbal camera.
⚫After using in seawater, soak and rinse thoroughly with clean fresh water before the
seawater dries out.
⚫If seawater or other sediments form on the gimbal camera, soak thoroughly with
fresh water and clean all sediments on the camera and motor before use. For more
information, check the drone’s “Maintenance manual”.
Installation
Install the Gimbal
1. Unscrew and take off the gimbal port cover plate
using a hex screwdriver. (Equipped with SplashDrone
4)
2. Plug the gimbal connector into the drone’s gimbal
port and screw it in place with a screwdriver.
󱛻󱛼󱛽Make sure the rubber ring is attached to the gimbal

3. Aline the holes on the base of the gimbal to the
bottom of the drone, screw in to mount the gimbal.
Make sure the camera is pointing to the front of the
drone.
Install SD Card
1. Open the soft rubber seal on the top of the
camera, insert the Mirco SD card in the correct
direction, press the Mirco SD card, the "click"
sound indicates that the installation is in place.
2. After installing the Mirco SD card, plug the rubber
seal back.
󱛻󱛼󱛽Make sure the rubber seal is tightly plugged in to
ensure waterproofing.
◆The GC1-S supports Mirco SD cards with a maximum capacity of 128GB. Since the
camera requires fast reading and writing of high-stream video data, please use
Mirco SD cards with Class 10 or UHS-1 or above to ensure proper functioning.
◆Do not insert or unplug the Mirco SD card during aircraft shooting, as data files may
be damaged or lost.
◆Once you are done recording, stop recording and save the file. If you turn off the
power directly before saving the files, the recording file will be lost.
ND Filter
GC1-S adopts a waterproof replaceable lens design. There is a separate SwellPro
waterproof ND filter kit to give you a broader range of possibilities in your photography.

To change the waterproof lens, simply unscrew the original lens, then screw the ND
filter lens back to the camera.
󱛻󱛼󱛽Ensure the orange rubber ring is attached to the camera when installing ND filters.
󱛻󱛼󱛽Ensure to aline the lens properly when installing ND filters as the lines on the screw
are very thin and can be damaged if not screw on properly.
After Use Casing
After using the gimbal camera, you can choose not to take off the gimbal camera and
put it directly into the case with the drone. Follow the following steps to make sure the
gimbal camera is properly secure after casing.
1. Remove the double-side-glued pad from the
gimbal box and paste the pad into the drone’s case
as showing to the left.
2. After cleaning and drying the gimbal camera and
the aircraft, secure the gimbal camera with the
fixing case, then put the aircraft and other parts into
the case. The case is secure and ready to be carried
or transported.

Calibration
If there are any abnormal movements being observed or the camera is not level, you
can recalibrate the gimbal camera to solve the problem.
Gimbal camera calibration is performed together with the aircraft gyroscope
calibration. To calibrate the gimbal camera, you just need to proceed with aircraft
gyroscope calibration.
To calibrate the gimbal camera:
1. Place the drone on a level surface, power on the remote
controller, then the drone. Wait for the aircraft to connect to the
remote controller.
2. Hold the left joystick down to its lowest position, then quickly
move the right joystick left to right, back and forth, until the front
and rear status indicators flash alternately, or the remote
controller screen prompts "WARNING aircraft Initializing,
Please Wait". The drone will now perform gyroscope
calibration. Now release the joysticks. This process will be
completed in 20 seconds. Do not move the drone during this
process.
3. When the front status indicators fast-flashing red and the rear
status indicators turn solid green, or "WARNING Aircraft
Initializing, Please Wait" prompt disappears, power off and
restart the drone. Gyroscope calibration is complete.
󱛻󱛼󱛽1) Do not calibrate the gimbal camera on a boat or other moving platforms.
