Installation instructions

1. Please choose the place with good ventilation and heat dissipation, and install the product in the wall without rain 
    erosion or special distribution box.

2. Determine the size at the selected construction position according to the product installation position dimension drawing.

3. Take out the fixing screws in the product and packaging box, first fix screw A, but do not tighten it too tightly, 
    then fix screw B, then fix screw C, and finally tighten all screws.
4. Install the power supply socket in a suitable position near the product. The socket should preferably have a switch
     to cut off the power when necessary.

5. Firmly install the outdoor antenna in a suitable position and adjust the orientation.

6. Connect the processed cable with the amplifier and antenna, and connect the antenna with different functions with 
    the corresponding input port of the amplifier, and do not connect it in the wrong position.

7. After connecting the antenna and the amplifier, turn on the power. First observe whether the power indicator of 
    the amplifier is on. The indicator is normal and the connection is successful.

8. Connect the TV signal meter or TV equipment at the test output end of the amplifier, adjust the TV signal 
    strength potentiometer of various frequency bands to the best effect, and finally connect the back-end user
     network with the main output port.

9. Make final adjustment to the user terminal according to the length and quality of the user cable. If necessary, 
    adjust the slope potentiometer to balance the signal attenuation of the cable.

10. Note that when the cable connected with the antenna is connected to the port of the amplifier, it can't be straight down. 
    It needs a wavy bend, so that the rainwater down the cable will not enter the amplifier.
