***-Working Principle:
 
        Adopting modern micro-electronics technology,this device can give out 2 kinds of electronic waves simultaneously and alternatively:super-low electro-magnetic wave,ultra -sonic wave,which can act upon the hearing and the nervous system of the mouse and make them unpleasant and uncomfortable.So the mouse will flee away.Even not flee away at once,the mouse will becaome listless,poor appetite and will loss their reproduction energy and invasion energy.
 
***-Usage and Coverage:
 
       (1). Mainly SD***9 can expel the mouse.Also it can have restrains to the following pests:cockroach,ant,spiders,cricket,bug,flea,even mosquitoes etc.
       (2). SD***9 can be used in the following places: family,ware-house,shop,hotel,restaurant,hospital,office,machine room,garden etc.
      (3).The effective coverage is around **0 square meter.That is enough for a family to use one unit.Certainly effectiveness will be better if two units used.
 
***-Operation Methods:
 
       (1).Just plug the device into the socket of AC**0V/*0HZ main power line.The device begins working when the red LED flashing.
       (2).Putting a AM radio within *0 cm from the device,you can hear a noise caused by ultra-sonic wave.When the noise occurred,ultra-sonic wave is working.Otherwise stop working.
       (3).Because of large output,a little heat will be produced which is a normal way.
 
***-Causions:
 
       (1).Never use the device outdoors and never put it in high-temperature and moist places.
       (2).AC **0V/.*0Hz power system must be confirmed before using it.
       (3).It should be used continuously without stopping.
       (4).It should be installed as low as possible from the ground because most of the mice running on the ground.
       (5).The effects will been seen immediately as soon as it used. But the best effects will be reached after using it continuously for **4 weeks.Sometimes the mouse may be more active at the beginning which shows the mouse have been irritated.Then they will be away after a period.
 
***-Main Specifications:
 
      (1).Power Voltage: AC**0V/*0HZ
      (2).Power Consumption: less than *0W.
      (3).Frequency Cocerage:
           Super low electro-magnetic wave:: 0.8HZ****8HZ      **0  seconds
           Ultra-sonic wave : ******5KHZ/*******0KHZ     *0 seconds
               
        The electro-magnetiv wave produced by our SD***9 only have a frequecy as low as several hertz.Also the frequencies of the ultra-sonic wave  overpass the audio range of the human-being.Meanwhile the output of the 2 waves is very small so they absolutely have no harm to the human-body.Otherwise there will be no any medical equipments made by super low frequency and ultra-sonc wave.
        According to the EMC report made by the authorized department:the electro-magnetic radiation levelfrom SD***9 is far more lower than EN standards and Chinese Standards.
