DJI PHANTOM 4 RTK (03) PDF Document

There are two kinds of altitudes displayed in the DJI GS RTK app for your DJI PHANTOM 4 RTK: absolute altitude and relative altitude.

Absolute altitude: The geographical attribute, in relation to longitude and latitude.

Relative altitude: The altitude data of the operation tasks relative to the Home Point. In the same operation, the absolute altitude for the same point will vary when taking off from locations with different elevations.

Before using the DJI PHANTOM 4 RTK, you should read the following documents:

1. In the Box

2. User Manual

3. Quick Start Guide

4. Disclaimer and Safety Guidelines

5. Intelligent Flight Battery Safety Guidelines

It is also recommended that you watch all tutorial videos and prepare for your first flight by reviewing the Quick Start Guide.

Follow these steps to prepare your DJI PHANTOM 4 RTK for flight:

1. Remove the gimbal clamp: Carefully remove the gimbal clamp from the camera.

2. Attaching the Propellers:

– Mount the propellers with black propeller rings to the motors with black dots.

– Mount the propellers with silver propeller rings to the motors without black dots.

– Press the propeller down onto the mounting plate and rotate in the lock direction until it is secured.

3. Battery Installation: Slide the battery into the battery compartment according to the arrow’s direction. A click sound indicates the battery is securely installed when the upper and lower buckles are in place.

1. Mounting the Remote Controller Battery:

– Slide the battery compartment cover lock on the back of the remote controller down to open the cover.

– Insert the Intelligent Battery into the compartment and push it to the top.

– Close the cover.

– To remove the battery, open the cover, press and hold the battery release button, then push the battery downward.

2. Mounting the Dongle and SIM Card:

– Lift the dongle compartment cover at the gap at its lower right corner, then remove it.

– Insert the dongle with the SIM card into the USB port and test it.

– Re-mount the cover. To secure it, open the silicone protectors, insert and tighten two Phillips screws, then close the protectors.

– Test procedure: Turn on the remote controller. In the DJI GS RTK app tap ≡ > and select Network Diagnostics. If the statuses of all devices are green, the dongle and SIM card are functioning properly.

3. Unfolding the Remote Controller:

– Tilt the display device to the desired position.

– Adjust the antennas so they are facing outward.

The DJI PHANTOM 4 RTK has the following flight modes:

P-mode (Positioning): This mode works best when the GNSS signal is strong. The aircraft uses the GNSS/RTK module and Vision System to automatically stabilize, navigate obstacles, and perform Photogrammetry or Waypoint Flight operations. When the GNSS signal is strong, it uses GNSS for positioning. With RTK enabled and good differential data, it provides centimeter-level positioning. If the GNSS signal is weak but lighting is sufficient, it uses the Vision System.

A-mode (Attitude): In this mode, GNSS and Vision System are NOT used for positioning. The aircraft only maintains altitude using the barometer. The aircraft enters A-mode only when there is a weak GNSS signal or compass interference and the Vision System is unavailable. In A-mode, the aircraft cannot position or auto-brake and is easily affected by its surroundings, which may result in horizontal shifting. Maneuvering can be difficult, so you should avoid flying in areas with weak GNSS signals or in confined spaces.

The Aircraft Status Indicators on your DJI PHANTOM 4 RTK communicate the system status of the flight controller. The Front LEDs glow solid red to indicate the front (nose) of the aircraft.

You can update the Home Point in the DJI GS RTK app during flight. There are two options:

1. Set the aircraft’s current coordinates as the Home Point.

2. Set the remote controller’s current coordinates as the Home Point.

Follow these instructions:

1. Go to DJI GS RTK > Fly.

2. Tap the three dots icon, select the aircraft icon, and then select the aircraft-in-crosshairs icon in Home Point settings to set the aircraft’s current coordinates as the Home Point.

3. Tap the three dots icon, select the aircraft icon, and then select the remote controller icon in Home Point settings to set the remote controller’s current coordinates as the Home Point.

4. The Aircraft Status Indicator will blink green to indicate the new Home Point has been successfully set.

Important Notes:

– When the Critical low battery level warning is triggered and the aircraft begins to land automatically, you can push the left stick upward to make the aircraft hover at its current altitude, giving you an opportunity to navigate to a more appropriate landing location.

– The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time and are automatically adjusted according to the aircraft’s current location and status.

– The Low Battery Warning threshold set in the app is only for an alert and will not trigger RTH.
