operating instructions, that is not covered by the warranty.
This device is forbidden to be used in the sun exposure. The operation panel will absorb heat and
cause heat dissipation problem. If the cable burnt out due to this, that is not covered by the warranty.
This equipment box can only be dragged on a flat surface, it is better to ask two people to carry the
box to avoid damage to the wheels, that is not covered by warranty.
No bumping and water entering during the transportation of this equipment, it must be packed in

eeeqqquuuiiipppmmmeeennnttt damage.

Warning

1.The battery interface of the onboard power supply module must be connected with the cable
connector first, then plug in the battery to prevent the ignition of the onboard power chip.

2. When the aircraft took off to 5m altitude by using the backup battery, turn on the cable power switch
of the tethered system; When the aircraft descended to 5m above the ground, the cable power should
be cut off in time.

3. The cable pulling and feeding speed is controlled in 3-4 gear. When pulling the cable, must keep the
cable taut to prevent the winch from being entangled by the cable. The raising and descent speed of
the aircraft is 1m/s.

4. It is forbidden to touch the cable directly (with insulated gloves) by hand when the cable power is
turned on, the high voltage 400vdc is injured, and the consequences arising from your own.

5. The on-board power supply module must be equipped with backup batteries, fully charged before
each flight to prevent aircraft from being forced to drop due to power-off, which will damage the
equipment.

6. This equipment is forbidden to be powered for a long time but never used. To prevent the cable from
being overheated and burned, the drone is required to fly in a 100m altitude.

7. Do not change the cable power voltage setting, if not, burning the onboard power supply module is
at your own risk.

observation window if the environment temperature is above 25 ；,lower the internal temperature of the
equipment. ；

6. Cable Outlet: Inside the brush there is a reciprocating screw rod, put the cable connector inside the brush
to reduce the dust and other debris；

7. Warning Light: When a system error occurs or a precautionary warning was set；LED will flash with the
buzzing sound,press the cable power switch to relieve alarm;

8. FC Interface: Connect with external ground station or required display equipment.

9. 220vac input: Using the power input cable provided by our company, power on the equipment.
Cable Assembly: Input 400~500vdc high voltage to the onboard power module ,the allowable current is
5~10A
Onboard Power: Convert high voltage into 48vdc for the motor.
