1. Working Principle:

        Adopting modern micro-electronics technology, this device can give out 3 kinds of electronic waves simultaneously and alternatively:electro-magnetic wave and 2 kinds of special ultrasonic waves ,which can act upon the hearing and the nervous system of the mice and make them unpleasant and uncomfortable. So the mouse will flee away. Because the frequencies of  the above electronic waves are changeable and alternative, so they can not make the mouse have adaptabilityand immunity.
         Moreover,according to the principle of the BIONICS,this device also can give out mewing and rat crying which will make the mouse flee away immediately.
         When there is a power failure, an additional rechargeable battery can be used.
         As a summary of the experiences in technology and marketing for nearly *0 years, we have made out this SD***7 brand new product which is powerful, multi-functional and effective.
 
2.Usage and coverage:

      (1). Mainly SD***7 can expel the mice. Also it can have restrains to the following pests:cockroach, ant, spiders, cricket, bug, flea, moth even mosquitoes etc.
      (2). Our products can be mainly used in the following places: warehouse, machine room, grain depot etc.
      (3). The effective coverage is around **0 square meter.

3.Operation Methods:

      (1) Plug one end of the attached power line into the Power Socket on the left right side in the back panel. And plug the another end of theattached power line into the AC**0V powersocket. Then the three LED in the front panel will be lighting.The green LED will indicate the device workingnormally.The yellow LED will indicate the ultrasonic waves working well  and the red LED will indicate the electromagnetic wave working well. The yellow LED will be blinking according to the frequency of ultrasonic wave .The red LED will be blinking and stopping according to the frequency ofelectro-magnetic wave.
       (2) There is a green TEST on the right of the back panel. Pressing this green, a very strong andharsh noise will be heard which will indicate the ultrasonic wave working normally. Please note: thisharsh noise can only be heard when the ultrasonic waves working.
        If press down the GREEN when there is no any person in the warehouse, thisdevice can give out intermittently harsh noise which can drive the mouse away promptly. 
       (3) There is a red marked as CAT/RAT CRY in the left of the back panel. Pressing down this red ,a cat crying and a rat crying can be heardalternatively. If press this red again, the crying will be stopped.
       (4) There is a DC socket in the right of the back panel. If there is a power failure,a rechargeable battery such as the car battery can be used instead. Please note: If the device is powered by a rechargeable battery, the electro-magnetic wave will be stopped working so the red LED will not be lighting. When the device is powered by AC power, the rechargeable battery will be charged automatically.
    Please be sure that the rechargeable battery will be connected in the correctPolarity
       (5) There are two FUSE in the back panel.One is for AC(0.5A) and the another is for DC(2A).If there is faulty in the device,these two FUSE will be checked in the first.

4.Cautions:

      (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) There should be no big obstructs in the front of the product because ultrasonic wave can not pass through the hard things.
      (5) There are four loud-speakers installed in three directions, so this device should be installed along the wall not in the middle of the room.
      (6) There will be some little hot in this device because the output power is rather big.
      (7) The electro-magnetic wave will be stopped working when a rechargeable battery is used. So the red LED will be stopped lighting in this case.
      (8) The effects will be seen immediately as soon as this device is used.But the best effectiveness will be reached after using it continuously for **4 weeks. Sometimes the mice may be more active at the beginning which shows the mice have been irritated. Then the mice will disappear after a period. Even few of mice remain temporarily, they will lost their ability of reproductions and invasions.
