1 ABOUT LEAD FREE SOLDER (PbF: Pb free)
Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead. We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu). This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used. Caution · PbF solder has a melting point that is 50°F ~ 70° F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with temperature control and adjust it to 700°F ± 50° F (370°C ± 10°C). In case of using high temperature soldering iron, please be careful not to heat too long. · PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C). · If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and be sure that any remaining is melted prior to applying the Pb solder. · When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the opposite side (See the figure below).
1.1.
Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper (Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu), or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the manufac turer's specific instructions for the melting points of their products and any precautions for using their product with other materials. The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

19.2. Power Supply Circuit
The power supply to the CPU (Digital, Analog) and RF IC from AC Adaptor (+12V) is shown in the diagram below. The base unit power supply is DC12V. The handset´s power is supplied from 3.6V battery (Nickel-Cadmium battery) which is installed in the handset. Power supply for transmitter is turned on by a press of "Talk" key on the handset. During the stand-by mode, the unit stops transmitting but receives the signal. Also during on-hook condition (the handset is placed on the base unit), backup power for memory of the last dialed number is supplied through the battery. The memory of this unit is not backed up by the current from the telephone line. The base unit DC power supply is regulated by Q18, the CPU power is regulated by Q19. The Q401, Q403 detects AC Adaptor power failure and maintains the unit security code.

19.4. Charge Circuit
Circuit Operation: When charging the handset on the base unit, the charge current is as follows; DC (JK2) L8 D6 Q14 Q24 L7 CHG+(Base) [CHG+(Handset) L4 Q9 BATT(1)....Battery....BATT(2) L5 CHG-(Handset)] CHG-(Base) L5, In this way, the CPU on both unit detects the fact that the battery is charged. The charge current is controlled by switching Q24, Q25 of Base Unit. The battery is charged in normal mode for 15 hours and then in trickle mode.
19.5. Telephone Line Interface
Function: · Bell signal detection · ON/OFF hook and pulse dial circuit · Side tone circuit Bell signal detection and OFF HOOK circuit: In the idle mode, Q103 is open to cut the DC loop current and decrease the ring load. When ring voltage appears at the Tip (T) and Ring (R) leads (When the telephone rings), the AC ring voltage is transferred as follows: JK1 (3): T L6 R184 R144 IC3D (12,13 14) C97 R148 Q20 IC2 (24) [BELL] JK1 (2): R L4 R183 R152 When the CPU (DSP) detects a ring signal and press the TALK Key on the handset. Q6 turns on and then RY1 turns on, thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow is for the loop current. T R160 L4 D2 RY1 R107 T7 R116 D5 L6 R161 R [OFF HOOK] ON HOOK Circuit: Q6 is open, RY1 disconnected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an on-hook condition. Pulse Dial Circuit: CPU (Hook) turns RY1 ON/OFF to make the pulse dialing via Q6. Make/Break ratio when dialing with the Handset: 40%:60% Side Tone Circuit: Basically this circuit prevents the TX signal from feeding back to RX signal. As for this unit, TX signal feed back from Q11 is canceled by the cancellor circuit of AGC.
19.6. DTMF
The DTMF signal is generated by five outputs of IC2 (CPU) and output to telephone line through the filter of IC3A which is a lowpass filter as shown below. The combination of five outputs "1", "0" makes 32 (=2 generator. 5) level signals and makes smooth waveform after filter like a DTMF

KX-TC2000SAB
19.7. Transmitter/Receiver
Base Unit and Handset are mainly consists of RF(Radio Frequency) IC and CPU. Base Unit and Handset transmit/receive voice signal and data signal through the antenna on carrier frequency. Signal Pass : *Refer to CDL TX/RX in Signal Route (P.46).
19.7.1. Base to Handset
Circuit Operation: The voice signal input from the TEL LINE interface goes to RF IC as shown in BLOCK DIAGRAM (BASE UNIT) (P.38). In the talk mode (off-hook) condition, the telephone line voice signal passes through D2, D3, D4, D5, RY1 (Relay), R107 and T7. The other party´s voice signal is coupled with T7 and amplified by Q11 and led to IC3-B (OP Amplifier device). And the signal goes through the compressor of RF IC, it is output to transmitter circuit. The signal of the data sent to the handset is applied in the anode of the variable capacitor diode (VARICAP : DV1). The capacitor of VARICAP is changing in accordance with the voice signal from telephone line interface or TX DATA signal from CPU. Therefore, the carrier frequency which is generated by TXVCO will be changing, and Frequency modulated RF signal is generated and amplified by RF AMP(Q3, Q4, T5). It pass through the Duplexer DPX1 and radiated from Antenna. The signal is transmitted from the base unit and received by the handset antenna and amplified by RF amplifier (Q1) through DPX1 as shown in BLOCK DIAGRAM (HANDSET) (P.39). And then it is converted to 10.7 MHz and 455 KHz Intermediate frequency by RF IC and related components. The demodulated audio signal is output from RF IC (DET OUT) and passed through "Expander" process to reduce noise, then voice signal amplified by "Receiver amplifier" is output to receiver (REC1). The receiver loudness is adjustable using "LOUD" key on the handset. Q2 controls the volume. When CPU (VOL1) becomes low, the volume becomes "HIGH", while CPU (VOL1) becomes high, the volume becomes "LOW". TX data (to Handset) CPU (VTX) becomes low to turn on the transmission power transistor Q2, and CPU (TX-data) sends data signal. It is FM-modulated by TXVCO and driven by RF AMP, then transmitted to the handset.

KX-TC2000SAB
19.7.2. Handset to Base
Circuit Operation: The voice signal from the handset user is picked up by the microphone (MC1), voice signal passes through "Compressor" process to reduce noise as shown in BLOCK DIAGRAM (HANDSET) (P.39). And the voice is FM-modulated by VARICAP (DV1). The carrier frequency is generated by TX VCO. The transmitter power transistor Q4 is turned on/off by CPU (VTX). The carrier signal is amplified by RF AMP and sent to the handset duplexer and antenna. The signal of 49MHz band (49.670~49.97MHz) which is input from ANT is filtered at DPX1 as shown in BLOCK DIAGRAM (BASE UNIT) (P.38), then it is input to RF IC. The signal input to RF IC is converted through Mixer inside of RF IC, RF filter (CF1, CF2) and Expander. The signal is transmitted from the handset and received by the base unit antenna and amplified by RF amplifier Q1, then it is converted to10.7 MHz and 455 KHz Intermediate by RF IC. The demodulated audio signal is output from RF IC (DET OUT) and passed through "Expander" process to reduce noise, then voice signal is led to LINE AMP. The signal is passed through TELEPHONE INTERFACE and Tel-line. RX data (from Handset): The data signal from handset (ex: Talk, ACK, COM) is also included in 49 MHz band same as the voice data. After second if filter, the data signal is made square shape by data limiting AMP of the RF IC. RX data is output to CPU (RX Data).
19.7.3. RF signal operation/control and PLL operation (RF UNIT)
Base unit radio frequency signal received by antenna passes through duplexer (DPX1). RF signal is amplified by RF AMP. RF signal received from RF IC is mixed with RX local frequency at Mixer to generate 10.7 MHz wide band IF. The reference frequency is generated by X1 10.245 MHz crystal. VC1 is the reference frequency for adjustment. The 10.7 MHz is mixed with reference and 455KHz narrow band IF is generated. The demodulation audio signal is adjusted to the maximum at T1. RF IC is controlled by CPU (RF_STB, DATA, CLK). The RX local frequency is generated by RXVCO.
