Attention to installation
1. Before power on, make sure the antenna connection is reliably . 그렇지 않으면, it will cause damage to the device.
2. Make sure that the voltage is within the range of use.
3. Please pay attention to the EMC of all the electronic equipments on your drone.
4. It is recommended that the antenna should be installed downward and keep the antenna away from the metal on the drone.
5. Make sure to use the matching antenna.
Before use
1. Make sure that all cables are connected correctly and firmly.
2. No foreign objects (예컨대. liquids, 모래, 기타) can be entered inside the device.
3. It takes 15 seconds for the device to start. Video and data cannot be transferred until the device has finished booting.
4. Please ensure that the environment in which the equipment is used is free of other electromagnetic interference.
5. When the signal weakens, you can improve the effect by changing the heading direction of the antenna.

개요
Industry drone market is developing very fast in recent years. The fight time and distance of drones are getting longer and longer. MK22/MK55, a long-range wireless transmission system, is designed for VTOL fixed wing and other long-range drones. The system can transmit video, fight control data, 짐벌 제어 데이터, and RC data simultaneously. With the advantage of high level intergration and powerful function, MK22/MK55 is a typical good product to meet long-range transmission requirements.
There are two frequency bands——800MHz、1.4GHz and 2.4GHz. Users can choose according to their needs. Please choose the suitable frequency band according to local regulations.
MK22 can transmit data and video to 22km, MK55 can transmit data and video to 55km, making it very suitable for long range drone.
If you use our recommend ground station, you only need one cable with connector to connect the device and your ground station.
*1Test under LOS and no interference conditions。
