1.Working Principle:
Adapting modernmicro-electronics technology,this device can give out 3 kinds of electronicwaves simultaneously and alternatively:super-low electro-magnetic wave and 2kinds of special ultrasonic waves ,which can act upon the hearing and thenervous system of the mice and make them unpleasant and uncomfortable.So themice will flee away.Even not flee away at once for few mice, they will becomelistless,poor appetite and will loss their reproduction and invasionability.
2.Usage andCoverage:
(1).MainlySD-042 can expel the mice.Also it can have restrains to the following
pests:cockroach,ant,spiders,cricket,bug,flea,motheven mosquitoes etc.
(2).Our productscan be used in the following places:family,ware-house,shop,hotel,Restaurant,hospital,office,machine room,gardenetc.
(3).Theeffective coverage is around 100 square meter.That is enough for afamily.Certainly effectiveness will be better if two devicesused.
3.Operation Methods:
(1).Just plugthe device into the socket of AC220V/50HZ main power line.The fisrt ultrasonicwave begins working when the green LED lighting.
(2)When the blueLED lighting and the green LED off,the second ultrasonic wave begins workingwhile the first ultrasonic wave stops working.
(3) When the redLED lighting ,the super-low electo-magnetic wave begins working .While when thered LED off,the super-low electro-magnetic wave stops working.
(4)Putting a AMradio within 30 cm from the device,you can hear a noise caused by ultra-sonicwaves.
4.Causions:
(1).Never usethe device outdoors and never put it in high-temperature and moistplaces.
(2).AC220V/.50Hz power system must be confirmed before using it.
(3).It should beused continuously without stopping.
(4).It should beinstalled as low as possible from the ground because most of the mice running onthe ground.Moreover there should be no obstacles in front of thedevice.
(5).The effectswill been seen immediately as soon as it used. But the best effects will bereached after using it continuously for 3-4 weeks.Sometimes the mice may be moreactive at the beginning which shows the mice have been irritated.Then the micewill be away after a period. Even not flee away at once for few mice, they willloss their reproduction and invasion ability.
5.MainSpecifications:
(1).PowerVoltage: AC220V/50HZ
(2).PowerConsumption: less than 15W.
(3).Frequencyand intermittence:
Super lowelectro-magnetic wave:: 0.8HZ----8HZ 160 seconds interval
Ultrasonic waves : 20---55KHZ/35 KHZ 80seconds interval
