Operation Guide

2.1 Battery Preparation

Drone Battery Charging:

1. Remove the battery from the drone and connect it to a USB charging cable.
2. Plug the USB charging cable into a USB charging port on a power bank or a USB adapter (5V/2A).
3. Charging indicators: The red light on the USB charging cable is solid, and the green light flashes while charging. Both lights are solid when fully charged.
4. Charging time: Approximately 180 minutes.

⚠️ Before charging, please read the instructions in the "Battery Safety" section of the "Disclaimer and Safety Guidelines" carefully.

⚡ Do NOT charge a battery immediately after a flight as the temperature may be too high. Please wait until it cools down to room temperature before charging again.

? Please use the original charging cable to charge the battery.

Changing Transmitter Batteries:

1. Open the battery cover on the back of the transmitter.
2. Insert three AAA batteries (not included). Then, close the cover.

? Low Battery Signal: The transmitter battery level icon ? on the LCD screen will keep flashing when the battery is low.

⚠️ Install batteries carefully. Do not mix old and new batteries. Do not mix different types of batteries.

2.2 Pre-Flight Preparations

Arms:

All arms of the drone are folded when it is packaged at the factory. First, unfold the front arms, then unfold the rear arms.

Drone Battery Installation and Removal:

• Installation: Insert the battery into the compartment located at the rear of the drone. Make sure that you hear a click sound, which indicates that the battery is firmly installed.
• Removal: Press the battery locks on the battery and carefully pull to extract the battery.

⚠️ The battery should be installed firmly. Otherwise, the flight safety of your drone may be affected. The drone may crash due to a power-cut during the flight.

2.2 Pre-Flight Preparations (cont.)

Propellers:

• Installation: Match the correct propeller (A or B) to the indicated motor (A or B). Secure the propeller using the provided screws with the screwdriver ?.
• Removal: Use a screwdriver ? to remove the screws. Then, remove the propeller.

⚠️ Please check that the propellers are properly installed and secured before each flight. Ensure the drone arms are unfolded and that the battery and propellers are mounted securely before takeoff.

Phone Holder:

Pull the phone holders out completely and place your mobile phone ? in them. Adjust the clamp to secure your mobile phone. You can adjust the tilt of the phone holder as needed.

2.3 Pre-Flight Checklist

• ✔️ Transmitter, mobile phone, and drone battery are fully charged.
• ✔️ The camera is clean.
• ✔️ There is nothing obstructing the motors.
• ✔️ The drone arms are unfolded.
• ✔️ The drone battery and propellers are mounted securely.
• ✔️ Use accessories provided by the company.

2.4 Flight - Pairing

Ensure that you are in an open, outdoor area before operating the drone.

1. Turn on the Transmitter: Slide the power switch ⚡ to the right. The transmitter will beep twice.

2. Turn on the Drone: Place the drone on a flat, level surface with its head facing forward and the tail facing the operator. Long press the power switch ⚡ to turn on the drone.

3. Auto-pairing: Successful pairing is confirmed when the transmitter emits a prolonged beep, and the transmitter signal strength icon ? on the LCD screen is at full bars.

2.4 Flight - Connect to Wi-Fi

Make sure the pairing has finished before going to the Wi-Fi settings on your phone.

1. Go to the Wi-Fi settings on your phone.
2. Connect to the drone's Wi-Fi network: HolyStoneGPS-******.
3. Run the HS GPS V4 app. A successful connection is confirmed when the drone's live video feed is displayed within the app interface.

? Connecting your phone to the drone's Wi-Fi may take some time. Please remain patient and wait for the connection to be established successfully.

? For optimal connectivity, if you're experiencing issues with the WIFI connection or the image transmission in the APP isn't displaying, it's advised to disable your phone's Bluetooth, Mobile Data, and VPN. Alternatively, switch your phone to airplane mode and attempt to reconnect.

? Please ensure that all permissions requested by the app are granted.

? The Wi-Fi network created by the drone does not have internet access. As a result, your cellphone might:

• Notify you that the connection isn't secure,
• Indicate there's no internet connection, or
• Suggest switching to cellular data.

(The exact wording may vary based on cellphone models.) Please disregard these messages. If prompted, select the option to remain connected to the current Wi-Fi.

2.4 Flight - Compass Calibration

The drone will perform a mandatory compass calibration before the initial flight. You can skip step 1 if this is the first time you fly your drone. At this moment, the four drone arm lights are alternately flashing in yellow.

STEP 1: Push both joysticks down to the bottom right corner at the same time to enter the compass calibration. The transmitter will beep twice and display 'GPS' on the LCD screen, indicating that the calibration has started. You can now proceed with Step 2.

STEP 2: Keep the drone parallel to the floor, and spin the drone three times. Once the transmitter beeps once, you can proceed to Step 3.

STEP 3: Point the head of the drone upward, and spin the drone three times. Once the transmitter emits a long beep, it means you have successfully performed a compass calibration.

? To ensure a stable flight, we recommend that pilots perform a compass calibration before each flight.

? We recommend that the pilot hold the drone approximately 3 ft above the ground while performing the compass calibration.

⚠️ DO NOT calibrate the compass in locations where magnetic interference may occur, such as close to magnetite deposits or large metallic structures like parking structures, steel-reinforced basements, bridges, cars, or scaffolding.

⚠️ DO NOT carry objects (such as mobile phones) that contain ferromagnetic materials near the drone during calibration.

2.4 Flight - GPS Signal Search

Please don't use the GPS mode when you are indoors.

After calibrating the compass, place the drone on a flat surface, away from external sources of signal interference. The drone will automatically perform a search for GPS signals, which will last for about 1 minute.

Successful GPS Signal Search Indicators: The front arm lights are solid RED, the rear arm lights are solid GREEN, and the LCD screen shows a satellite connection count of 7 or more.

Searching for GPS Signals: The lights on the front drone arms are solid RED, and the lights on the rear drone arms are solid YELLOW.

? If the GPS signal is weak or if you intend to fly this drone indoors, you can hold the GPS switch ?️ Switch button on the transmitter for 2 seconds to exit GPS mode. The LCD screen will show "GPS OFF" at this time. However, please note that all GPS-related functions will be unavailable when the drone is in this mode.

2.4 Flight - Gyro-Calibration

Make sure to place the drone on a level surface before calibrating the gyro. Simultaneously push the left joystick ?️ Left and the right joystick ?️ Right to the bottom left corner to calibrate the gyro. All drone lights will blink, then turn solid, which indicates that the calibration is completed.

? We suggest that the pilot perform a gyro-calibration before each takeoff and after any crash.

2.4 Flight - Unlock the Motors

Unlock the Motors: Short press the [Unlock Button] (likely the GPS button). The motors rotate, and the drone is unlocked.

Locking the Motors: Short press the [Lock Button] again, and the motors stop immediately. The drone is locked.

2.4 Flight - Takeoff/Landing

Please unlock the motors before takeoff.

Takeoff: Short press the [Takeoff/Landing Button]. The drone will automatically take off and hover at approximately 5 ft.

Landing: When the drone is flying, short press the [Takeoff/Landing Button]. The drone will automatically land on the ground.

Transmitter Reception Range

When controlling the drone, promptly adjust the orientation and distance between the transmitter and the drone to ensure that the drone always remains within the optimal reception range.

Optimal Reception Range: The diagram shows the transmitter and drone in close proximity and aligned.

Weaker Signal: Diagrams illustrate scenarios where the drone is too far, obstructed, or not properly aligned.
