Adaptinghigh-tech methods,SD-048 can give out two kinds of peculiar ultrasonic waveswhich can irritate the nervous and audio system of the mouse, make themuncomfortable and unpleasant and drive them away. The frequency of theultrasonic waves are always changing which can not make the mouse have any"adaptability" and "immunity".

Adapting apeculiar automatic control circuit, this device will be working when thevehicles put out and will be stopped when the motor working in thevehicle.

2---Usage &Coverage:
