Earthquake Alarm
1. Open the packaging and put the seismograph horizontally beyond the range of children or pets. The water bubble must be in the middle, and then turn on the switch. If the seismograph is always calling, then turn off the power. Heighten the four corners of the seismograph by papers, and then turn on the switch. Adjust the seismograph until there is no sound when you turn on the switch. 2. Away from magnetic interference, such as electrical appliances, mobile phones, iron cabinets, etc. (more than 30cm). 3. The seismograph has been fully charged before sales. Please charge it once a year. Because it adopts relay technology so that the standby achieves zero consumption, only the battery will have power consumption. 4. The light above the seismograph is the alarm of earthquake; the light below is the alarm of magnetic anomaly. If the light below is flashing and calling, please observe if the compasses are rotating irregularly, and then observe the phenomena such as weather and earthquake clouds, for the megnetic pole will be turbulence when the earthquake is coming. 5. The compass of the seismograph have lost the functions of compass under the constant magnetic fields in the seismograph. It will rotate non-stop only when the magnetic field greatly changes (the vertical magnetic field appears before earthquake). When the alarm occurs, the earthquake magnitude can be judged according to the rotating intensity of the compasses and this is what differences among the detectors with p wave detecting,which can be triggered earlier in advance.
