Adapting modernmicro-electronics technology,this device can give out 2 kinds of electronicwaves simultaneously and alternatively:super-low electro-magnetic wave,ultra-sonic wave,which can act upon the hearing and the nervous system of the mouseand make them unpleasant and uncomfortable.So the mouse will flee away.Even notflee away at once,the mouse will becaome listless,poor appetite and will losstheir reproduction energy and invasion energy.

2---Usage andCoverage:

(1).MainlySD-049 can expel the mouse.Also it can have restrains to the followingpests:cockroach,ant,spiders,cricket,bug,flea,even mosquitoesetc.

(2).SD-049 can be used in the following places:family,ware-house,shop,hotel,restaurant,hospital,office,machine room,gardenetc.

(3).The effective coverage is around 100 square meter.That is enough for afamily to use one unit.Certainly effectiveness will be better if two unitsused.

3---Operation Methods:

(1).Justplug the device into the socket of AC220V/50HZ main power line.The device beginsworking when the red LED flashing.

(2).Putting a AM radio within30 cm from the device,you can hear a noise caused by ultra-sonic wave.When thenoise occurred,ultra-sonic wave is working.Otherwise stopworking.

(3).Because of large output,alittle heat will be produced which is a normal way.

4---Causions:

(1).Neveruse the device outdoors and never put it in high-temperature and moistplaces.

(2).AC220V/.50Hz power system must be confirmed before using it.

(3).Itshould be used continuously without stopping.

(4).Itshould be installed as low as possible from the ground because most of the micerunning on the ground.

(5).Theeffects will been seen immediately as soon as it used. But the best effects willbe reached after using it continuously for 3-4 weeks.Sometimes the mouse may bemore active at the beginning which shows the mouse have been irritated.Then theywill be away after a period.

5---MainSpecifications:

(1).PowerVoltage: AC220V/50HZ

(2).PowerConsumption: less than 10W.

(3).Frequency Cocerage:

Super lowelectro-magnetic wave:: 0.8HZ----8HZ     160 seconds

Ultra-sonic wave :  20---55KHZ/55---110KHZ     80 seconds

               

Theelectro-magnetiv wave produced by our SD-049 only have a frequecy as low asseveral hertz.Also the frequencies of the ultra-sonic wave overpass the audiorange of the human-being.Meanwhile the output of the 2 waves is very small sothey absolutely have no harm to the human-body.Otherwise there will be no anymedical equipments made by super low frequency and ultra-soncwave.

According to theEMC report made by the authorized department:the electro-magnetic radiationlevel

from SD-049 isfar more lower than EN standards and Chinese Standards.
