                            Operation Description

The transmitter use a SOC (system on a chip) chip MA3201, most of function can be
finished by one chip, such as key-press detective, and it is the part of RF operating
circuit. The transmitter is made of U1 (MA2301), SENSOR U4 A7530, U2 is ID code
storage IC, U5 is power management IC. U5 is the circuit of boost pressure,it make
the battery’s voltage reach 3V to support the mouse working. Clock oscillator is made
of U1 internal circuit and X1,X2 surrounding circuit, and it can supply the power for
clock pulse. Once start the SWR, SWL, SWM, SWZ, SWB, SWF switch, U1 will be
process. U4 is Laser chip, it can react the movement of tabletop then deliver to U1,
U1 will finish all the data code internal and modulate, then enlarged by internal circuit,
at last it delivered to the air by antenna. U2 is ID code memory,after the mouse and
receiver code connect together successfully, U2 will record this code and backup it for
next time.

Antenna is formed by a copper trace on the PCB. Common grounding on PCB is not
connected to real external ground. Power supply is DC 3V by two “AAA” batteries.
