1.WorkingPrincipal:
TakingHigh-tech methods and Micro-electronics technology,Two kinds of deferentultrasonic waves will be amplified up to 50W output.And then usingspecially-made ultrasonics speakers and taking a special connectioin methods,the ultrasonic waves will be spread to every conners in the wearhouse,whichwill strongly irritate the nervous system and audio systems of the rat and drivethem away.
Because the frequency of the two ultrasonic waves will be changing andalternative,and also the two deferent waves will changed automatically at acertain time,so the rat can not have a "adaptability"and"immunity".
Thebest results will be reached after using SD-020 for 2-3 weeks.
Little ofrat even maybe remain but they have lost their energy of destroy andreproductions.After using this machine in the first week,the rat may be moreactive which just shows that the rat have been irritated and will disappear verysoon.
2.Usage andCoverage:
SD-020machine is specially designed and used in large warehouses such as big gainwharehouse,cool warehouses,big supper markets etc.
Theeffective area can be covered around 1000-2000 sqm.
3.OperationMethods:
(1).SpeakersInstallation:
(A).5-8 attached specially- made speakers will be fixed and hung on the ceilingof the warehouse evenly.
(B).Connect the speakers in parallel with two pcs of commonwires.(Note:
the samepoles + - of the speakers must be connected together).
(C).Connect the two pcs of wires onto the OUTPUT terminals in the back of themachine.(one red and another black terminal must be used.)
(2).Atthe first,turn off the "power switch" on the left side of the front panel.Thenplug the "power line" into the AC220V socket and the Fan in the back panel willbe working at this time.Meanwhile,V meter in the front panel will be pointed onaround DC28V.
(3).Accordingto the area of the warehouse,please select the "Power Selections" knob.If thearea is above 1000 sqm,50W can be chosed.If less than 1000 sqm, 25W or 12W canbe chosen. 50W is recommended.
(4).IntervalSelection.There are 3 options: 16",4" and 0"(no stopping).16" isrecommened.
(5).SelectFrequency Knob onto 24H or 12H .12" is just for testing.
(6).Putthe" power switch" onto "ON" position,the the green LED will be lighting,red LEDflashing in every second frequency and the yellow LED will be flashing whenultrasonic waves working.
Atthis time,the Voltage Meter V will show around DC28V and Current meter A willshow around 1.7 A.
(7).Usingthe attched specially-made ultrasonics testing meter and testing in deferentplaces in the warehouse,the testing meter pointer will flicker which indicatesthe machine is working normally.(during the working time).You can
Chose "High" or"Low" position according to the intensity of the ultrasonic wave.
Also youcan use a AM radio for simple testing.A kind of special
DA-DA or"JI-JI "sound will be heard during working time if you put the radio under thespeakers.
4.Caustions:
(1).AC220/50--60Hzmust be confirmed before using .
(2).Heatwill be produced when the machine working. So the Fan in the back of the machinemust be kept working and no any obstructions in front of the fan especiallyworking in 50W output.
(3).IFworking stopped,the two FUSE tubes will checked at the first.(AC fuse is 1A ansDC fuse is 3A).
(4).Theeasy-burnning materials must be kept away from the machine.
5.TechnicalSpecifications:
(1).InputVoltage: AC220V/50--60Hz
(2).Output: 12W/25W/50W
(3).WorkingVoltage and Current: DC28V/1.7A
(4).FrequencyCoverage: 20KHz---55KHz.
