Operational Description

DESCRIPTION OF CIRCUIT OPERATION BASE UNIT : The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin No.3 of CON1 is sent to U2 (COMPANDER IC) Pin No.16 for Expansion. The expended audio signal output from Pin No.19 is coupled to Q2,3 during the TALK mode. The audio signal is sent to the Telephone Line via hybrid Transformer HBY1. The demodulated data code from CON1 Pin No.3 is fed to Q5. It’s output is connected to Pin No.14(Data Reference Input Pin) and 15(Data input Pin) of IC3. The Audio signal receiving from TEL-LINE is inputted to U2 Pin No.8 for compression. The compressed audio signal from Pin No.1 of U2 is connected to Pin No.10 of CON1 for Audio signal modulation. Pin No.31 of IC3 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. Relay control is done by Pin No.18 of IC3. Ring signal monitored by U4 (PHOTO COUPLER IC) is detected by Pin No.16 of IC3 and Base Unit sends Ring Data Code to hand set. DTMF dialing is generated by IC3 Pin no.20~25 and this signal is sent to TEL-LINE through the Q2,Q3,Q4 and hybrid Transformer HYB1. When the hand set is placed on the base cradle, the charging is detected by Pin No.13 of IC3 and IC3 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.17 of IC3 (the micro processor) and the base set goes to Stand-By mode after 20 sec. The power of the base set is supplied by U3(5V REGULATOR IC). LED display is controlled by Pin No.9 of IC3. HAND SET : 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 IC4(Expander input). The audio output from Pin No.19 of IC4(Expender output) is output to the Receiver unit with HAC compatibility through Q2. The demodulated data code from Pin No.3 of CON1 is fed to Q5. It’s output is connected to Pin No.14(Data Reference Input Pin) and 15(Data input Pin) of IC3. Voice signal from C-MIC is coupled to Pin No.8 of IC4. The voice signal is compressed by Compressor of IC4 and Voice signal output of Pin No.1(IC4) is connected to Pin no.10 of CON1 for Audio signal modulation. Pin No.23 of IC3 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.5 of IC3 Key board operation is monitored by Pin No.11,16~18,28~30 of IC3. Key Tone Signal and the ringing Signal from Pin No.9 of IC3 drives the BUZZER. 1.
