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 Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions. Attention: A nickel metal hydride battery that is recyclable powers the product you have purchased. Please call 1-800-8-BATTERY (1-800-822-8837) for information on how to recycle this battery. 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). Remove all of the excess solder Component pin Solder (Slice View) Downloaded from www.Manualslib.com manuals search engine 4 Component KX-TG4732B/KX-TG4733B/KX-TG4734B/KX-TGA470B 2.2.1.

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 59 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. 3.0V R141 R142 R162 R160 D143 C101 D101 Q142 3 2 4 1 L101 SA101 C168 C171 R171 C176 R177 C142 R164 R145 C173 C163 ( ) R161 + C161 Q171 Pin 16 of IC501 Q161 C165 ( ) C164 ) C175 ( C178 R165 R172 R167 R163 RX R178 R175 C167 R176 Q141 L102 C102 C111 R111 C113 R114 Q111 D113 3.0V BELL Pin 59 of IC501 Downloaded from www.Manualslib.com manuals search engine 14 C112 R112 C184 R113 R181 C181 ( ) TX Pin 28 of IC501 L1T L1R TEL JACK Hook Pin 6 of IC501 P101 KX-TG4732B/KX-TG4733B/KX-TG4734B/KX-TGA470B 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.

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.

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.
