For Service Technicians • Repair service shall be provided in accordance with repair technology information such as service manual so as to prevent fires, injury or electric shock, which can be caused by improper repair work. 1. When repair services are provided, neither the products nor their parts or members shall be remodeled. 2. If a lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced. 3. FASTON terminals shall be plugged straight in and unplugged straight out. • ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover plastic parts boxes with aluminum foil. 2. Ground the soldering irons. 3. Use a conductive mat on worktable. 4. Do not grasp IC or LSI pins with bare fingers. 2 Warning 2.1. Battery Caution 1. Danger of explosion if battery is incorrectly replaced. 2. Replace only with the same or equivalent type recommended by the manufacturer. 3. Dispose of used batteries according to the manufacturer’s Instructions. 2.2. 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. 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 ± 20 °F (370 °C ± 10 °C). • Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB. • PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100 °F (600 °C). • 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). 4 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 2.2.1. 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 manufacturer'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: 0.3 mm, 0.6 mm and 1.0 mm. 2.3. Discarding of P. C. Board When discarding P. C.

Signal Flowchart in the Radio Parts Reception A voice signal from TEL line is encoded to digital data "TXDATA" by BBIC (IC501) in a base unit. Then TXDATA goes to RF PART and it's modulated to 1.9 GHz. The RF signal is amplified and fed to a selected antenna. As for a handset RF, RF signal is received in one antenna. BBIC down-converts to 864 kHz IF signal from RX signal and demodulates it to digital data "RXDATA". BBIC (IC1) converts RXDATA into a voice signal and outputs it to speaker. Transmission A voice signal from microphone is encoded to digital data "TXDATA" by BBIC (IC1) in a handset. Then TXDATA goes to RF PART, and it's modulated to 1.9 GHz. The RF signal is amplified and fed to a antenna. As for a base unit RF, RF signal is received in two antennas. BBIC (IC501) compares RF signal levels and selects the antenna to be used. Then BBIC down-converts to 864 kHz IF signal from RX signal in the selected antenna, and demodulates it to digital data "RXDATA". BBIC (IC501) converts RXDATA into a voice signal and outputs it to TEL line. 8 VBAT RF_PART RSTN 9 RESET TXON TXn TXp RXON RXn RXp ANT2 ANT1 STM/CKM 3 KEY 1 VDD FLASH MEMORY IC601 KEY C, D, E CLK,DO DL,CS ANT1 ANT2 SPOUTP SPOUTN BBIC EEPROM MEMORY IC611 VCC X501 13.824 MHz IC501 SP SCL, SDA WP KEYS ANS_LED VCCA MSG_LED PDN DET DOUBOUT VBAT VCCPA VBAT_APU VCC_IF VCC_FE VCC_VCO LOUT LIN HOOK DCIN 2 DCIN 1 BELL HSMIP HSMIN 3.0V RECEIVE AMP Q171 SIDE TONE CIRCUIT Q161 RESET IC IC331 3.0 V REGULATOR IC302 INUSE DETECT 1 R131, R133 BELL DETECT Q111 D101 R371 R372 DCM DCP L1R - + CHARGE_CONTACT DC JACK TEL JACK L1T KX-TG4021/4022/4023 BLOCK DIAGRAM (Base Unit_Main) INUSE DETECT 2 R151,R152 RLY Q141 4.2.

Circuit Operation (Base Unit) General Description: (BBIC, Flash Memory, EERROM) is a digital speech/signal processing system that implements all the functions of speech compression, record and playback, and memory management required in a digital telephone answering machine. The BBIC system is fully controlled by a host processor. The host processor provides activation and control of all that functions as follows. 4.4.1. BBIC (Base Band IC: IC501) • Voice Message Recording/Play back The BBIC system uses a proprietary speech compression technique to record and store voice message in Flash Memory. An error correction algorithm is used to enable playback of these messages from the Flash Memory. • DTMF Generator When the DTMF data from the handset is received, the DTMF signal is output. • Synthesized Voice (Pre-recorded message) The BBIC implements synthesized Voice, utilizing the built in speech detector and a Flash Memory, which stored the vocabulary. • Caller ID demodulation The BBIC implements monitor and demodulate the FSK/DTMF signals that provide CID information from the Central Office. • Digital Switching The voice signal from telephone line is transmitted to the handset or the voice signal from the handset is transmitted to the Telephone line, etc. They are determined by the signal path route operation of voice signal. • Block Interface Circuit RF part, LED, Key scan, Speaker, Telephone line. 4.4.2. Flash Memory (IC601) Following information data is stored. • Voice signal ex: Pre-recorded Greeting message, Incoming message 4.4.3. EEPROM (IC611) Following information data is stored. • Settings ex: message numbers, ID code, Flash Time, Tone/Pulse 11 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.4.4. Power Supply Circuit/Reset Circuit The power supply voltage from AC adaptor is converted to VBAT (3.0V) in IC302. And +3.0V for peripherals and analog part is insulated from VBAT by Doubler of BBIC. Circuit Operation: 12 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.4.4.1. Charge Circuit The voltage from the AC adaptor is supplied to the charge circuits. 13 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.4.5. Telephone Line Interface Telephone Line Interface Circuit: 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, Q141 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: T → L101 → R111 → C111 → Q111 → BBIC pin 5 [BELL] When the CPU (BBIC) detects a ring signal, Q141 turns on, thus providing an off-hook condition (active DC current flow through the circuit). Following signal flow is the DC current flow. T → L101 → D101 → Q141 → Q161 → R163 → R167 → D101 → L102 → P101 → R ON HOOK Circuit: Q141 is open, Q141 is connected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an onhook condition. Pulse Dial Circuit: Pin 6 of BBIC turns Q141 ON/OFF to make the pulse dialing. 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 Q161 is canceled by the canceller circuit of BBIC. 14 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.4.6. Parallel Connection Detect Circuit/Auto Disconnect Circuit Function: In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have a circuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone connected in parallel is on hook or off hook by detecting changes in the T/R voltage. Circuit Operation: Parallel connection detection when on hook: When on hook, the voltage is monitored at pin 17 of IC501. There is no parallel connection if the voltage is 0.54 V or higher, while a parallel connection is deemed to exist if the voltage is lower. Parallel connection detection when off hook: When off hook, the voltage is monitored at pin 18 of IC501; the presence/absence of a parallel connection is determined by detecting the voltage changes. If the Auto disconnect function is ON and statuses are Hold, receiving ICM, OGM transmitting, BBIC disconnects the line after detecting parallel connection is off hook. 15 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.4.7. Calling Line Identification (Caller ID)/Call Waiting Caller ID Function: Caller ID The caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone company to utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has been entered for the circuit being used. The data for the caller ID from the telephone exchange is sent during the interval between the first and second rings of the bell signal. The data from the telephone exchange is a modem signal which is modulated in an FSK (Frequency Shift Keying) * format. Data "1" is a 1200 Hz sine wave, and data "0" is a 2200 Hz sine wave. There are two types of the message format which can be received: i.e. the single message format and plural message format. The plural message format allows to transmit the name and data code information in addition to the time and telephone number data. *: Also the telephone exchange service provides other formats. 16 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT Call Waiting Caller ID Calling Identity Delivery on Call Waiting (CIDCW) is a CLASS service that allows a customer, while off-hook on an existing call, to receive information about a calling party on a waited call. The transmission of the calling information takes place almost immediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the new call. Function: The telephone exchange transmits or receives CAS and ACK signals through each voice RX/TX route. Then FSK data and MARK data pass the following route. Telephone Line → P101 → L101, L102 → C121, C122 → R121, R122 → IC501 (25, 24). If the unit deems that a telephone connected in parallel is in use, ACK is not returned even if CAS is received, and the information for the second and subsequent callers is not displayed on the portable handset display. 17 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 4.5.

How to Replace the Flat Package IC Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins. 13.1.1. Preparation • PbF (: Pb free) Solder • Soldering Iron Tip Temperature of 700 °F ± 20 °F (370 °C ± 10 °C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil. • Flux Recommended Flux: Specific Gravity → 0.82. Type → RMA (lower residue, non-cleaning type) Note: See About Lead Free Solder (PbF: Pb free) (P.4) 13.1.2. How to Remove the IC 1. Put plenty of solder on the IC pins so that the pins can be completely covered. Note: If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter. 2. Make a few cuts into the joint (between the IC and its pins) first and then cut off the pins thoroughly. 3. While the solder melts, remove it together with the IC pins. When you attach a new IC to the board, remove all solder left on the board with some tools like a soldering wire. If some solder is left at the joint on the board, the new IC will not be attached properly. 57 KX-TG4021LAT/KX-TG4022LAT/KX-TG4023LAT/KX-TGA403LAT 13.1.3. How to Install the IC 1. Temporarily fix the FLAT PACKAGE IC, soldering the two marked pins. *Check the accuracy of the IC setting with the corresponding soldering foil. 2. Apply flux to all pins of the FLAT PACKAGE IC. 3. Solder the pins, sliding the soldering iron in the direction of the arrow. 13.1.4. How to Remove a Solder Bridge 1. Lightly resolder the bridged portion. 2.
