Used with DJI RS 3 Pro

1. Attach the LiDAR Range Finder to the hot shoe of the camera and tighten the lock knob. (Figure A)
2. Connect the power and communication port of the LiDAR Range Finder to the video transmission/LiDAR Range Finder port of DJI RS 3 Pro using the multi-camera control cable provided. (Figure B)
3. The LiDAR Range Finder is powered by DJI RS 3 Pro and turns on after the gimbal has power. The visible light camera view (not the view of the attached camera) displays on the touchscreen of the gimbal.

• **** The 1/4″-20 thread to cold shoe adapter can be detached. The user can also attach the LiDAR Range Finder to a camera cage via the 1/4″-20 screw.
• If the camera view on the touchscreen is blurred, use the LiDAR Range Finder control cable instead of the multi-camera control cable to obtain a clear camera view. Note: the end with the shorter part of the cable should be connected to the power and communication port of the LiDAR Range Finder, the longer part of the cable should be connected to the video transmission/ LiDAR Range Finder port of the DJI RS 3 Pro.

Lens Profile
Tap Lens Profile to calibrate the lens, autofocus can be used after calibration.

• During camera lens calibration, it is recommended to shoot as few subjects as possible. The subject should be a person or flat surface with discernible features (such as a picture on the wall). The accuracy of the lens calibration will affect the autofocus performance.
• The lens parameters will be stored in the focus motor after calibration.
  Only focus motor calibration is required after choosing the lens profile.
  There is no need to calibrate the lens again.

Steps:

1. Set the function of the front dial for the gimbal to Focus the Motor. Power on DJI RS 3 Pro, swipe up from the bottom of the touchscreen, and tap Dial Function. Scroll to
   select Focus Motor.
   

2. Tap < and swipe down from the top of the touchscreen to return to the homepage.
   Swipe right from the left of the touchscreen to enter the LiDAR page. Tap the icon on the bottom right corner of the touchscreen to enter LiDAR settings.
   

3. Tap Lens profile. Tap + and tap Set, then tap +/- or drag the bar to input focal length.
   

4. Tap < and then tap Start Motor Calibration. The focus motor will begin to rotate when calibrating. Tap Confirm when the calibration is complete.

5. Power on the attached camera before calibrating the lens. Focus on a subject in the center of the camera view that is approx. 1 m (0.7 m to 1.2 m) away. A white box will appear on the subject. Check if the subject is in focus on the attached camera view (not the touchscreen). Adjust the front dial of the gimbal until the subject is in focus and tap Confirm.
   Repeat the previous step with a subject that is approx. 4 m (3.5 m to 4.7 m) away.
   The lens profile is complete after the lens calibration has been completed. DJI RS 3 Pro supports up to three lens profiles. The indicator light of C1, C2, and C3 turn on to
   indicate which lens profile is applied.
   For the existing lens profile, delete the lens profile and recalibrate the lens if autofocus is inaccurate. Motor calibration is needed if the endpoint of the focus motor is
   changed due to the mounting position being changed. Tap Motor Calibration or press the Function button twice to start calibration.

Non-Calibration Lenses
LiDAR Range Finder can be used with specific lenses, which do not require calibration.
Refer to the DJI LiDAR Range Finder product page on the official DJI website for supported lenses. Connect the data port of the lens to the USB-C port of the focus motor using the camera cable provided.

Installation Distance
The installation distance is defined as the distance between the focus plane of the camera and the LiDAR Range Finder. The default distance is 75 mm, which is the length of the LiDAR Range Finder mounting bracket plus the length of the LiDAR Range Finder. Fine-tune the value to improve the autofocus accuracy. When mounting the LiDAR Range Finder to other positions, such as the top of the camera lens, adjust the distance to compensate for errors.
AF Tracking Sensibility Settings
Supports 5 levels. Level 1 offers the slowest change in focus. Level 5 offers the fastest change in focus.
ActiveTrack Settings
ActiveTrack Speed: Indicates the speed of the gimbal when using ActiveTrack. Select from Slow, Medium, and Fast settings.
Tilt Follow Switch: Enable or disable tilt follow as needed. The tilt axis follows the gimbal movements when turned on.

Autofocus

Autofocus can be used after the lens profile is completed.
Focus Mode
Tap the bottom left corner icon to switch between Wide and Spot modes.

In Wide mode, the LiDAR Range Finder automatically recognizes people in the camera view and focuses on the people nearest to the center. A white box appears on the person selected. Adjusting the front dial of the gimbal can switch the subject and lock into focus. A yellow box will appear on the locked subject.
In Spot mode, the LiDAR Range Finder will focus on the subject inside the focus box.
Drag the box or tap a subject to use autofocus.

Using ActiveTrack Pro
In Wide mode, press the trigger of the gimbal to enable ActiveTrack when a subject is selected. The box turns green, which indicates that ActiveTrack is enabled.
Use the control stick to adjust the frame. If the frame turns red, the subject is lost.
Press once on the trigger to exit ActiveTrack, press twice on the trigger to exit ActiveTrack and recenter. The frame turns white to indicate that ActiveTrack is disabled.
AF/MF Mode
Press once on the AF/MF Switch or the M button of the gimbal to switch between autofocus and manual focus. Note that the M button function should be set prior to LiDAR AF/MF. In Manual focus mode, adjust the front dial to focus. Half-press the camera control button of the gimbal to focus each time.

• **** DO NOT use corrosive organic solvents such as alcohol wipes to clean the lens of the LiDAR Range Finder.
• Make sure the LiDAR cameras are not blocked. Otherwise, the autofocus will be inaccurate.

Using LiDAR Range Finder Only

Follow the steps below to use the LiDAR Range Finder without DJI RS 3 Pro:

1. Calibrate the lens via DJI RS 3 Pro, the camera parameter will be stored in the focus motor.
2. Attach the LiDAR Range Finder and focus motor to the camera, and then connect the power and communication port of the LiDAR Range Finder and one of the USB-C ports of the focus motor using the multi-camera control cable. Connect an external power supply (7 to 16 V) to the other USB-C port of the focus motor to power the LiDAR Range Finder and focus motor. (Figure C)
3. Power on the external power supply, and then press twice on the Function button to start motor calibration. Press the AF/MF button to switch the focus mode to autofocus, the indicator glows solid green indicating autofocus is available.

Firmware Update
