DESCRIPTION OF CIRCUIT OPERATION AUTOMIC DIGITAL SECURITY A special security code (up to 65,536 combinations) is automatically and randomly generated to insure privacy. 1. BASE UNIT The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin No.3 of CON1 is sent to IC2 (COMPANDER IC) Pin No.16 for Expansion. The expended audio signal output from Pin No.19 is coupled to Q8 during the TALK mode. The audio signal is sent to the Telephone Line via Q3. The demodulated data code from CON1 Pin No.3 is fed to U5-B. It’s output is connected to Pin No.31(Data Reference Input Pin) of IC4. The Audio signal receiving from TEL-LINE is input to IC2 Pin No.8 for compression. The compressed audio signal from Pin No.1 of IC2 is connected to Pin No.10 of CON1 for Audio signal modulation. Pin No.21 of IC4 generates data codes that should be transmitted to the hand set. The data code is connected to Pin No.10 of CON1 for Data modulation. Line control is done by Pin No.10 of IC4 Ring signal monitored by U5-A is detected by Pin No.9 of IC4 and Base Unit sends Ring Data Code to hand set. DTMF dialing is generated by Pin no.38 of IC4 and this signal is sent to TEL-LINE through the Q8 and Q3. When the hand set is placed on the base cradle, the charging is detected by Pin No.8 of IC4 and IC4 sends I.D data codes to handset for security code setting. When the handset is far away from base unit, squelch circuit of IC1 in RF part operates and Pin No.13 of IC1 goes “HI”. This Squelch Detection Signal will be detected by Pin No.30 of IC4 (the micro processor) and the base set goes to Stand-By mode after 20 sec. The power of the base set is supplied by IC5(5V REGULATOR IC). IN-USE LED display is controlled by Pin No.23 of IC4. 2. HAND SET Receiver unit The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin No.3 of CON1 is connected to Pin No.16 of U2-A(Expander input). The audio output from Pin No.19 of U2-B(Expender output) is output to the with HAC compatibility through Q8. The demodulated data code from Pin No.3 of CON1 is fed to Q10,Q9. It’s output is connected to Pin No.26(Data input Pin) of U1. Voice signal from C-MIC is coupled to Pin No.8 of U2-A. The voice signal is compressed by Compressor of U2 and Voice signal output of Pin No.1(U2-A) is connected to Pin no.10 of CON1 for Audio signal modulation. Pin No.29 of U1 generates data codes that should be transmitted to the base set. the data code is connected to Pin No.10 of CON1 for Data modulation. During the charging, Charging is detected by Pin No.23 of U1 Key board operation is monitored by Pin No.50~53,66,67 and 58~61 of U1. Key Tone Signal and the ringing Signal from Pin No.62,68 of U1 drives the BUZZER. LCD display is controlled by Pin No.1~9,70~100 of U1. Volume is controlled by Pin No.11,12 of U1 and drives the Q7,Q15 3.
