                           Circuit ‘s operation Description for DS-2075

     This circuit is mainly consisted of convertor IC(U4), IC(U3),MCU IC(U2).
       IC U4 provides the circuit with a stable 3Vvolts d.c and U3 provide the circuit with a
stanble 4 V . to keep the circuit working.。when the mouse is moving on the desktop, photoelectric
processor IC-U1collect optical signals reflected by the desktop,and transfer them into the MCU
IC-U2,then processed and managed. By MCU,together, they are sent to the FSK circuit。In the
MCU IC-U2,there is internal RF Generator,the electric signals out from MCU will be generated,
and output the data from 8# feet of U2,and radiate the signal to outside。
     MCU will provide and generate a code from the 22# feet of IC-U2 when you press the ID
button,at the same time ,MCU will storage this code, and keeping the ID code unchanged until
out of power。
     The MCU IC-U2 have two functions of sleep and wake up. For saving up the capacity of
power, the circuit will keep sleeping model when the mouse has stopped on the desktop for a
fixture time; you can press any key or wheel switch to let it work again.
