- 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 range 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 effection, 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.
