Amplifier opening test
1）If possible, connect the amplifier grounding post to the grid ground with electric wire.
2）Check whether the connection joint between the repeater and the antenna is in good contact.
2）Plug the DC plug of the 5V/2A power adapter provided with the host into the DC +5V jack of
the cell phone companion host and the AC plug into the nearest 220V power socket.
3) refer to the display function of the operating instructions, check the parameters of the display
and determine whether the host is working properly.
4) Use the cell phone to test the signal strength and call quality within the coverage area.
