Guangdong KK22 2.4G Remote control

Attention: When the aircraft is not inserted with TF card or the TF card is malfunction, photos and videos taking can not be done by pressing the button of the remote controller, but by the icon on the APP interface.

One-key takeoff/landing

• After the B7 unlocked, short-press the “ ” button (indicated as below), the aircraft will automatically take off and hover at 1.5m altitude.
• When the aircraft is flying, short-press the “ ” button (indicated as below), the aircraft will automatically land on the ground.

In aircraft’s landing automatically, press any joystick, the aircraft will exit the mode.

One-key RTH button

• Press the “ ” with the buzzer having “Di”, it means the auto- return home is on.
•  The aircraft will return to lasted home point. Press the button shortly again, the return home will be closed.

Low battery warning

• If the rear indicator light flash slow, the battery icon in transmitter LCD screen is “ ”. As only the aircraft is beyond 30 meters altitude or 100 meters distance, the aircraft will return home automatically. As long as the aircraft is in 100 meters distance, the user can cancel the return by “ ”.
• When the battery icon “ ” is shown on the LCD screen (Pic. 2) with steady “beep …beep” sound, it means that the aircraft battery is in low voltage. At this time, the aircraft front lights glow solid on and rear lights flash rapidly. The aircraft will return when the altitude is over 15m or the distance is over 15m; if either the flying altitude or flying distance is less than 15m, the aircraft will land to the ground.

Remote control low voltage warning

When the “ ” icon appears on the LCD screen and the remote control emits “beep beep” sound, it means that the remote control battery is nearly out of power. Please change new battery for the remote control.

Signal strength indicator

• Signal strength bar “ ” shows the strength of the received signal. The more, the better.
• When the strength bar “ ” changes from weak to strong circularly, it means that the remote controller is under signal connection status.
• There are 2 situations that the strength bar “ ” is less than 2 grids or no displaying with steady long beep sounds.
  •  The distance between the aircraft and the remote controller is too far causing a weak signal.
  • The battery is removed after the aircraft connects to the remote controller.

Optimal transmission zone

To obtain a satisfied flight experience, please make sure that your B7 is flying ahead of the remote controller and no obstacles between the aircraft and the remote controller.

1. Forbid to fly in following locations, surroundings and scenes.
2. The drone is for 16+ years old, otherwise please play under qualified supervisor.
3. Please comply with local flight laws and regulations, fly reasonably and legally.

Flight Environment Requirements

1. Please don’t fly in such bad weather conditions as high temperature, snow, strong wind (≥level 5), rain or fog.
2. Always choose a wide open area for every flight. Tall structures and large metal structures may affect the accuracy of the onboard compass and GPS system.
3. Well away from people and property. Never fly directly over people or animals.
4.  To minimize interference, please do not fly the aircraft in locations near power lines, base stations, electrical substations and broadcasting towers.
5. Aircraft and battery performance is subject to environment factors like temperature. Be very careful when flying over
   6KM above sea level since the performance will be affected. Your B7 cannot use GPS within the polar regions.

Flight limits and GEO zones

Abide by all laws and regulations when flying your B7. Flight limitations are applied by default to help users operate this product safely and legally. Flight limitations include altitude limits, distance limits and GEO Zones. Altitude limits, distance limits and GEO Zones function concurrently to manage flight safety when operating in GPS Mode.

Pre-flight Checklist

1. The aircraft, remote controller and mobile device are full charged;
2. The propellers are installed correctly;
3. The arms and propellers are unfolded;
4. Ensure the camera lens are clean;
5. Only use the designated or approved parts by manufacturer. Unauthorized parts or parts not from certified manufacturers may cause malfunction or safety issues.

Aircraft Operations

Signal connection between the aircraft and remote controller

• Keep pressing the red button “ ” and turn on the remote controller (Pic. 1). The remote controller makes 2 beep sounds, and the indicator light “ ” keeps flashing; the remote controller is under signal connection status.
•  Power on the aircraft (Pic. 2). The aircraft will make beep sounds with front and rear lights flashing and will automatically link to the remote controller. Once the remote controller sends out a long beep sound and the indicator light of the remote controller turns from flashing to solid on and the signal icon “ ” is shown on the LCD screen, it means that signal connection is succeeded.

• Signal connection is done once for all if the remote controller is not linked to other aircraft.
• Set the connection one by one to avoid signal connection error.

Aircraft initialization detection

After frequency matching, the aircraft will enter into initialization test. In this time, the yellow red green light flash alternately. The aircraft will finish the initialization about 8s in ground, then enter into compass calibration.

Attention: If the aircraft is always in initialization, can’t enter compass calibration. Please place the aircraft in ground, let the aircraft do gyro calibration to exit the initialization.

Aircraft compass calibration

1. Compass calibration should be performed after successful aircraft initialization detection.
2. Aircraft compass calibration should be done for every flight. That is to say, if changing new battery or the battery is reinstalled, compass calibration should be done again.

Two steps of compass calibration:

• Step 1: Horizontal calibration
  After the initialization, the yellow indicator light flashing, the aircraft enters into the compass horizontal calibration. As seen below picture, rotate the aircraft horizontally for about 3 circles until the indicator light turns green and flash, which means the horizontal calibration is complete.

• Step 2: Vertical calibration
  Hold the aircraft with camera facing up, and rotate it 360 degrees along the central axis for about 3 circles until the lights of the aircraft change from flashing to solid on, the compass calibration is successful.

Attention: To fly at GPS mode, please choose an open and wide space for the flight, and make sure that the satellite amount is over 7.

• Step 2: Vertical calibration
  Hold the aircraft with camera facing up, and rotate it 360 degrees along the central axis for about 3 circles until the lights of the aircraft change from flashing to solid on, the compass calibration is successful. After the initialization, the yellow indicator light flashing, the aircraft enters into the compass horizontal calibration. As seen below picture, rotate the aircraft horizontally for about 3 circles until the indicator light turns green and flash, which means the horizontal calibration is complete.

• Please do not calibrate the compass in strong magnetic area, such as magnetic field, parking place or construction areas with underground reinforcement.

• Please do not carry magnetic materials with you (such as keys, cell phones, etc) when calibrating compass.

• Please keep away from big metal when calibrating compass.

Manual gyro calibration

After the aircraft and the remote controller are banded, set the aircraft on flat ground and follow the indication photo as below to calibrate the gyro. Once the aircraft lights turn from flashing to solid on, it means that the gyro calibration is succeeded.

The gyroscope calibration was done at the factory. Gyroscope calibration is not needed unless the aircraft can not exit the aircraft initialization detection procedure.

How to lock and unlock the aircraft

• Unlock the aircraft
  Short-press the red button “ ” . The motors rotate and the aircraft is unlocked.

• Lock the aircraft

There are 2 ways to lock the aircraft that you can find it as below:

• Method 1: After the aircraft landing, pull the throttle to the bottom and hold for 3 seconds. The motor will stop and aircraft will be locked.
• Method 2: The aircraft will be locked automatically once no any operation in 15 seconds after unlocked.

Emergency stop:

• Beyond 30 meters distance and 15 meters altitude, press the “ ” and hold for 3 seconds, the aircraft will be stop.
• The function is only for emergency, please don’t use it in normal flight.
