Installing the Airborne Module
1. Using the standard version of the airborne module as an example: Secure the module to the drone; connect the device's power cable to the module; connect the drone's power supply to the "BAT OUT" port and the drone's battery to the "BAT IN" port.
2. Extend the cable in advance based on the flight altitude. If the flight altitude is less than 50 meters, it is recommended to extend the cable for at least 50 meters to ensure good heat dissipation.
Device Operation Steps
1. Connect the device (⑩) to a 220V AC power source via the power cable, then push the main power switch (⑥) upward to power on the device.
Please note that the tethered power switch (③) and the cable auto-rewind switch (④) should be in the off position before powering on.
2. Fly the drone to a height of approximately 1 meter above the ground, then turn on the tethered power (③). 3. After the flight, land the drone on the ground and turn off the tethered power supply (③) to disconnect the 400V high-voltage power supply.
4. Unplug the cable from the onboard module and press the cable auto-rewind switch (④) to retract the cable. After retraction is complete, press the button again to stop retraction.
5. Push down the main power switch (⑧) and unplug the power cord.

Indicator Light Status
1. Solid: Standby mode
2. Blinking: Tethered power is on
3. Blinking: A fault has occurred and the device will emit a beeping sound.
※ If the indicator light flashes while the device is powered on, check whether the tethered power switch (③) or the automatic winch switch (button ④) is pressed.

・This product carries a 400-volt high voltage. Improper use may cause personal injury. Please read the product manual carefully before using this product. Do not touch the tethered cable and plug connector while the tethered power is on.
・When the tethered cable connector is disconnected from the drone, always turn off the tethered power switch. When pulling cables while powered, wear insulating gloves for personal protection. Any electric shock is considered improper operation, and the customer is solely responsible for any consequences.
Because tethered cables can heat up, if the drone is heavily loaded or requires extended flight time, all tethered cables must be removed from the enclosure. Otherwise, the temperature inside the enclosure may rise to unsafe levels.
The maximum flight time for a tethered aircraft is 12 hours. For missions exceeding 12 hours, it is recommended to replace the aircraft or allow the aircraft to rest for one hour before continuing.
