How does it work: The machine should be held in hand when working. The SMA socket on the top is for antenna. The two oval holes on the upper right of the face board are for loudspeaker. In the middle of the left side are 10 grades of LED indicators, the first of which indicates the power and the others indicate the strength of detected signals. The last one shows the strongest signal. The knob at the bottom is for power and detecting threshold modulation. Screw the antenna to the socket. Loosen the screws on the back cover. Pull out the inner battery pool and press the 9V packed cell into it with the poles in the right direction (make sure the power knob is off before the battery is installed). And then fix the back cover with tightened screws. Turn the bottom knob to the right until it make a sound of "ka". The power is turned on now and all the LED indicators are also lighted. Continue to turn the knob to the right and the LED indicators will be off one by one from right to left. Meanwhile, the tone of the loudspeaker goes from high to low. Generally the machine become most sensitive when the third LED indicator from the left is just turned off. When the machine gets closer to the working tap device, the LED indicators will be turned on one by one and the tone of the loudspeaker will become higher and higher. There may be still a small distance from the tapping device and reset the knob to make the machine in the most sensitive state as said before. When the LED indicators and the tone of the loudspeaker have great change, the location of the tapping device can be determined.
