4. Repairable equipment and circuit explanation
4.1 Repairing method
If Transmitter cannot send output message, it have to change new one
4.2 Circuit explanation
If User press specific Switch of transmitter, CPU (U3) make inherent serial value and
Encr yption value, so it print what CPU make data, at the same time , RF IC get to be ENABLE.
Printing data are falsified into TxIC(U2) and it synthesize through X1. Compound frequency
are amplified by TxIC(U2) and it transmit through antenna from matching circuit diagram of
output or it transmit RANDOM DATA through 3D LF Antenna and print to encrypt result
