Precaution of Safety

It requires professional skills and technical knowledge to install and operate R/C model properly. Incorrect installation and operation will result in severe property loss and personal injuries HK-7X GHz control system is exclusively designed for civil use of R C models Don t use it in any other flying machines. The governmence for R/C model is different in different place, therefore, please consult your local regulatory body and follow the rules and regulations to operate legally. Radio wave transfers almost in straight routine in 2.4GHz, please make sure there is no any obstacle when you are operating the product. The antenna tube should point at the controlled model to ensure efficient control, and keep conductive materials away from receiver and transmitter. If there is prang, collision, welter and other accidents when operating, please test all the things before next operating. Always keep electrical components away from small children. Stop flying long before your batteries become low on charge. Do not rely on your radio's low battery warning. systems, intended only as a precaution, to tell you when to recharge. Always check your transmitter and receiver batteries prior to each flight. Before flying, be sure that the frequency you intend to fly with is not in use, and secure any frequency control device (pin, tag, etc.) for that frequency before turning on your transmitter. It is never possible to fly two or more models on the same frequency at the same time Even though there are different types of modulation AM FM PCM only one model may be flown on a single frequency at any one time While you are getting ready to fly, if you place your transmitter on the ground, be sure that the wind won t tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the engine to speed up. Also, damage to your transmitter may occur. Before taxiing, be sure to extend the transmitter antenna to its full length. A collapsed antenna will reduce your flying range and cause a loss of control. It is a good idea to avoid pointing the transmitter antenna directly at the model, since the signal is weakest in that direction. Don t fly in the rain! Water or moisture may enter the transmitter through the antenna or stick openings and cause erratic operation or loss of control. If you must fly in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never fly if lightning is expected.

Notice:

1)HK-7X 2.4GHz remote controller system sustain multiple receivers operation and long-distance scaning, so please make sure there's only your radio scaning. If there is any person who also use HK-7X 2.4GHz remote controller system at local, please operate only after other users pare the signal. HK-7X supports seven models saving in one transmitter, they are numbering as n1 to n7. The binding will save the serial number in receiver. So if you bind one receiver with n1, it can only work when the transmitter is switched to n1.
2.Connect Devices to Receiver

Connecting all devices and parts to the corresponding channels. Take notice of 3P signal wire must be connected in right way, or it will cause the severe damage to certain device or fail to work. There are some corresponding symbols of 3P on one side of the receiver: (-) means cathode of power connected to the earth, usually links to the black line or brown line of 3P signal wire (+) means the anode of power, usually links to the red wire of 3P singal wires. (s) means signal wire, usually links to the white or yellow wire of 3P singal wires.Notice:please assess the power demand of the receiver of model when selecting the electricity supply style, ensure the receiver can get enough power supply when using, the voltage of the receiver not less than 4.2V at any time.

4.Control Distance

All remote equipment has an effective range. It's not the same on the ground, and on the water surface or in the sky; It's not the same on flat ground and complex land; It's not the same in rainy days and in sunny days; And besides, the external electrical environment is changing continuously. It's quite necessary for the users who want to control at a long distance to test effective distance beforehand.Radio wave transfers almost in a straight line, please make sure there is no object between antenna and the controlled model. And the antenna should point at receiver's antenna, and keep the controlled model in certain distance where the model can be seen.controller system
3.Binding Transmitter and Receiver
Before using the 2.4GHz remote controller system, you must bind the transmitter and the receiver. Binding them as following steps: 1) Power on receiver by plugging the ESC line, then plug the 'BIND line' into the 'BIND' slot of receiver. Then the LED of receiver will flash three times per second. Then you can remove the "BIND" line'.
