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).

4.2.4.1.
Speakerphone Circuit
Function
The circuit controls the automatic switching of the transmitted and received signals, to and from the telephone line, when the
unit is used in the hands -free mode.
4.2.4.2.
Circuit Operation
The speakerphone can only provide a one-way communication path.
In other words, it can either transmit an outgoing signal or receive an incoming signal at a given time, but cannot do both simultaneously. Therefore, a switching circuit is necessary to control the flow of the outgoing and incoming signals.
This switching circuit is contained in IC601 and consists of a Voice Detector, TX Attenuator, RX Attenuator, Comparator and
Attenuator Control. The circuit analyzes whether the TX(transmit) or the RX(receive) signal is louder, and then it processed the
signals such that the louder signal is given precedence.
The Voice Detector provides a DC input to the Attenuator Control corresponding to the TX signal.
The Comparator receives a TX and a RX signal, and supplies a DC input to the Attenuator Control corresponding to the RX signal.
The Attenuator Control provides a control signal to the TX and the RX attenuator to switch the appropriate signals on and off.
The Attenuator Control also detects the level of the volume control to automatically adjust for changing ambient conditions.
1. Transmission signal path:
The input signal from the microphone is sent through the circuit via the following path: MIC Pin 9 of IC601 Pin 10 of
IC601 Pin 3 of IC601 Pin 4 of IC601 R601 C602 L107 Q107 Tel line.
2. Reception signal path:
Signals receive from the telephone line are outputted at the speaker via the following path: Tel line Q107 Q401 C404
R600 C603 Pin 27 of IC601 Pin 26 of IC601 Pin 19 of IC601 Pin 15 of IC601 Speaker.
3. Transmission/Reception switching
The comparison result between TX and RX outputs as a DC level of Pin 25 of IC601. TX level is high ...... Pin 25 = Pin 21 6mV RX level is high ...... Pin 25 = Pin 21 - 150mVComparator output is connected to the attenuator control inside of IC601.
4. Voice detector
The output of the mic amp (Pin 10 of IC601) is supplied to Pin 13 of IC601 as a control signal for the voice detector.
5. Attenuator control
The attenuator control detects the setting of the volume control through Pin 24 of IC601 to automatically adjust for changing
ambient conditions.

Caller ID Detect Circuit
Function (FSK Signal)
The caller ID is a changeable 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 "0" is a 1200 Hz sine wave, and data “1” 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.

Pin Name
Description
NO.
1
RR
A resistor to ground provides a reference current for the transmit and receive attenuators.
2
RTX
A resistor to ground determines the nominal gain of the transmit attenuator. The transmit channel gain is inversely proportional to
the RTX resistance.
3
TXI
Input to the transmit attenuator. Input resistance is nominally 5.0 kohms.
4
TXO Output to the transmit attenuator. The TXO output signal drives the input of the transmit level detector, as well as the external circuit which drives the telephone line.
5
TLI
Input of the transmit level detector. An external resistor ac coupled to the TLI pin sets the detection level. Decreasing this resistor
increases the sensitivity to transmit channel signals.
6
TLO
Output of the transmit level detector. An external resistor and capacitor set the time the comparator will hold the system in the
transmit mode after speech ceases.
7
RLI
Input of the receive level detector. An external resistor ac coupled to the RLI pin sets the detection level. Decreasing this resistor
increases the sensitivity to receive channel signals.
8
RLO Output of the receive level detector. An external resistor and capacitor set the time the comparator will hold the system in the
receive mode after the receive signal ceases.
9
MCI
Microphone amplifier input. Input impedance is nominally 10 kohms and the dc bias voltage is approximately equal to VB.
10
MCO Microphone amplifier output. The mic amp gain is internally set at 34 dB (50 V/V).
11
CP1
A parallel resistor and capacitor connected between this pin and Vcc holds a voltage corresponding to the background noise level.
The transmit detector compares the CP1 voltage with the speech signal from CP2.
12
CP2
A capacitor at this pin peak detects the speech signals for comparison with the background noise level held at CP1.
13
XDI
Input to the transmit detector system. The microphone amplifier output is ac coupled to the XDI pin through an external resistor.
14
SKG High current ground pin for the speaker amp output stage. The SKG voltage should be within 10 mV of the ground voltage at pin
22.
15
SKO Speaker amplifier output. The SKO pin will source and sink up to 100 mA when ac coupled to the speaker. The speaker amp gain
is internally set at 34 dB (50 V/V).
16
V+
Input dc supply voltage. V+ can be powered from Tip and Ring if an ac decoupling inductor is used to prevent loading ac line signals. The required V+ voltage is 6.0 to 11 V (7.5 V nominal) at 7.0 mA.
17
AGC A capacitor from this pin to VB stabilizes the speaker amp gain control loop, and additionally controls the attack and decay time of
this circuit. The gain control loop limits the speaker amp input to prevent clipping at SKO. The internal resistance at the AGC pin is
nominally 110 kohms.
18
CS
Digital chip select input. When at a Logic "0" (<0.7 V) the Vcc regulator is enabled. When at a Logic "1" (>1.6 V), the chip is in the
standby mode drawing 0.5 mA. An open CS pin is a Logic "0". Input impedance is nominally 140 kohms. The input voltage should
not exceed 11 V.
19
SKI
Input to the speaker amplifier. Input impedance is nominally 20 kohms.
20
Vcc
A 5.4 V regulated output which powers all circuit expect the speaker amplifier output stage. Vcc can be used to power external circuitry such as a microprocessor (3.0 mA max). A filter capacitor is required. The MC 34018 can be powered by a separate regulated supply by connecting V+ and Vcc to a voltage between 4.5 V and 6.5 V while maintaining CS at a Logic "1".
21
VB
An output voltage equal to approximately Vcc/2 which serves as an analogue ground for the speakerphone system. Up to 1.5 mA
of external load current may be sourced from VB. Output impedance is 250 ohms. A filter capacitor is required.
22
Gnd
Ground pin for the IC (except the speaker amplifier).
23
XDC Transmit detector output. A resistor and capacitor at this pin hold the system in the transmit mode during pauses between words or
phrases. When the XDC pin voltage decays to ground, the attenuators switch from the transmit mode to the idle mode. The internal
resistor at XDC is nominally 2.6 kohms.
24
VLC
Volume control input. Connecting this pin to the slider of a variable resistor provides receive mode volume control. The VLC pin
voltage should be less than or equal to VB.
25
ACF
Attenuator control filter. A capacitor connected to this pin reduces noise transients as the attenuator control switches levels of
attenuation.
26
RXO Output of the receive attenuator. Normally this pin is ac coupled to the input of the speaker amplifier.
27
RXI
Input of the receive attenuator. Input resistance is nominally 5.0 kohms.
28
RRX A resistor to ground determines the nominal gain of the receive attenuator. The receive channel gain is directly proportional to the
RRX resistance.

10.2. 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.
10.2.1. Preperation
• PbF (: Pb free) Solder
• Soldering Iron
Tip Temperature of 700F ± 20F (370C ± 10C)
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).
10.2.2. 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 land 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.

10.2.3. 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.
10.2.4. How to Remove a Solder Bridge
1. Lightly resolder the bridged portion.
2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.
