Terms of Use:

Please connect the antenna first before the power of transmitter starts, otherwise the transmitter will be burned/destroyed easily because most of the energy is consumed in it and the excess power cannot be released by the antenna.
When the transmitter is working, don't touch the antenna because of the large power. Otherwise the high temperature of antenna will hurt your hands!!
Please choose the right power for this product.
The transmitter must work at the ventilated place. It can make the using life of transmitter much longer.
Wireless transmission reception result might be affected due to different environmental and topographical conditions such as the weather, noise, the structure/material of the building, etc. For a better reception, make sure that the transmitter and the receiver are placing at least 5 feet above ground. Antenna must be attached on the transmitter before power up. Otherwise, the transmitter will be burned out because the excess power cannot be released by the antenna.
This product must be used within the law. We are not liable under any circumstances if the device(s) is used for illegal purposes.

User Instruction:

Transmitter is 12V regulative power, receiver is 12V switch power, the center of jack is positive.
Transmitter has a special cable for connection. The red connector is for power input, the black one is for vidicon power supply, the yellow one is for video output, and the white one is for audio output. The jack connects to the transmitter directly.
Receiver has a special cable for audio and video. It connects the receiver and monitor. The VIDEO OUT in the receiver should be connected with the VIDEO IN of the monitor. The AUDIO OUT in the receiver should be connected with the AUDIO IN of the monitor.
In default, you needn't adjust the system when all the components are connected together, the channel of transmitter and receiver are matched.
Please connect the antenna first before the power of transmitter starts, otherwise the transmitter will be destroyed easily because most of the energy is consumed in it. If you want to change the channel, you can change the jumper's place, the jumper is at the side of transmitter. The switch must be changed at the same time, the switch is near the AUDIO OUT of receiver.
Please select the outside directional antenna if the output is large power. If you use the small all-direction antenna, it will produce big transmitting current, the temperature of antenna will rise, transmitting power of antenna go down.
The power of higher than 12V is not permitted.
Make sure which is the positive or negative of power connector. The inside is positive, the outside is negative.
If you want to transmit to a longer distance, please use the directional antenna, the transmitting distance of it is 2 or 3 times than the all-direction antenna's.
