Getting Started

Charging

To charge DJI OM 4, connect a USB adapter (not included) to the charging port using the power cable (included). The battery is fully charged when the battery level indicators turn off. Charging time: 2.5 hours (tested in the environment temperature of 25° C when using a 10W charger) Max runtime: 15 hours (tested with the gimbal balanced and held steadily. This value should be taken as a reference only) DJI OM 4 can be used as a power bank. Connect your mobile phone to the USB-A port. If DJI OM 4 is powered on, the mobile phone will begin to charge. If DJI OM 4 is powered off, press the M button once to start charging.

Attaching the Phone

The provided magnetic phone clamp and magnetic ring holder can be used to mount a phone to DJI OM 4.

Using the Magnetic Phone Clamp: attach the magnetic phone clamp in the center of the phone.

|

  * Make sure the direction of the magnetic phone clamp is the same as shown and it is in the middle of the phone. Otherwise, the gimbal performance may be affected.
  * Adjust the phone clamp and make sure it is as vertical like the phone.
  * For optimal performance, use the provided riser pad if using a phone less than 7.5 mm thick or weighing less than 160 g.

---|---

Using the Magnetic Ring Holder:

|

  * Only attach the magnetic ring holder to phones that are supported by DJI OM 4. Refer to the DJI OM 4 Mobile Phone Compatibility List at www.dji.com/om-4 for more information.
  * The sticker must be used when attaching the magnetic ring holder to a mobile phone made of glass. DO NOT attach the magnetic ring holder directly to a mobile phone made of glass.
  * DO NOT attach the magnetic ring holder to a mobile phone case. Otherwise, the gimbal performance may be affected.
  * Make sure no air is trapped between the sticker and the mobile phone. Otherwise, the mobile phone may fall off.

ActiveTrack Select Box :
ActiveTrack 3.0 has been optimized for tracking human subjects with a head and shoulder model along with face detection using deep learning algorithms. The subject will remain in the center of the camera view by default. The camera view can be adjusted manually. There are three ways to use ActiveTrack 3.0:
a. Drag a box on the screen in the camera view in DJI Mimo. A green box around the subject indicates ActiveTrack 3.0 is successfully enabled. Tap the X icon on the top corner to stop tracking.
b. Enable Gesture Control in DJI Mimo and perform a palm or V gesture for one to two seconds when facing the camera. The back camera will detect the nearest head and shoulders and start to track the subject. The front camera will detect the nearest face and start to track the subject.

The differences between the head and shoulder tracking and face tracking are that head and shoulder tracking supports 360° tracking while face tracking does not. Also, the detection range of the cameras are different. The detection range between the back camera and the gesture is 0.5 to 4 m, and the distance between the front camera and the gesture is 0.5 to 2 m. Note that ActiveTrack 3.0 may consume more power and cause the temperature of the mobile phone to increase.
c. Press the trigger once to start or stop ActiveTrack 3.0. When using ActiveTrack 3.0, move the joystick to adjust the camera view. Perform a palm or V gesture to stop recording.
