GH-2410 CIRCUIT DESCRIPTION BASE UNIT : The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin no.3 of J 3 is sent to IC2 (COMPANDER IC) Pin no.16 for Expansion. The expended audio signal output from Pin no.19 is coupled to Q8,the audio signal is sent to the Telephone Line through Q3.. The demodulated data code from J3 Pin no.3 is Generated by IC-324.. It’s output is connected to CODE Input Pin no.31 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 J3 for TX modulation. Pin no.21 of IC4 is the output port for data codes that should be transmitted to the handset the data code is connected to Pin no.10 of J3 for modulation. Line controlling is done by Pin no.10 of IC4. Ring signal monitored by IC7 (PHOTO COUPLER IC) is detected by Pin no.9 of IC4 resulting a data code to the handset. DTMF dialing is generated by IC4 Pin no.38 this signal output through the Q4.Q3. When the handset is placed on the base cradle, the charging is detected by Pin no.8 of IC4 and IC4 sends data codes to handset for security code setting. When the handset is far away form base unit, squelch circuit of IC4 operates and Pin no.30 of IC4 goes “HI”. This will be detected by the micro processor and after 20 sec. go to Stand by mode. The power to the base unit is supplied by IC5(5V REGULATOR IC). LED display control Pin no.22 of IC4. HAND SET : The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin no.3 of CON1 is connected to U2-B Pin no.16 Expander input. The audio output from U2-B Pin no.19 is finally amplified by Q8 and A.C coupled to the Receiver unit with HAC compatibility. The demodulated data code from CON1 Pin no.3 is fed to Q9,10. Q9 is connected to (DATA IN) Pin no.26 of U1. Voice signal from C-MIC is coupled to Pin no.8 of IC-PH1. The voice signal is compressed by U2 and output Pin no.1 is connected to Pin no.10 of CON1 for modulation. Pin no.29 of U1 is the output port for data code that should be transmitted to the base unit. This data code is connected to the Pin no.10 of CON1 for modulation. During the charging, it is detected by U1 Pin no.23. Key board operation is monitored by Pin no.50~ 61of U1. Key Tone and the ringing from Pin no.62 of U1 drives the BUZZER. 1.
