6 HOW TO REPLACE FLAT PACKAGE IC
6.1. Preparation
• • SOLDER
Sparkle Solder 115A-1, 115B-1 or Almit Solder KR-19, KR-19RMA
•
• Soldering iron
Recommended power consumption will be between 30 W to 40 W.
Temperature of Copper Rod 662 ±50°F (350 ± 10°C)
(An expert may handle between 60 ~ 80 W iron, but beginner might damage foil by overheating.)
•
• Flux
HI115 Specific gravity 0.863
(Original flux will be replaced daily.)
6.2. Procedure
1.Temporary fix FLAT PACKAGE IC by soldering on two marked 2 pins.
*Most important matter is accurate setting of IC to the corresponding soldering foil.
2.Apply flux for all pins of FLAT PACKAGE IC.
3.Solder employing specified solder to direction of arrow, as sliding the soldering iron.
6.3. Modification Procedure of Bridge
1. Re-solder slightly on bridged portion.
2.Remove remained solder along pins employing soldering iron as shown in below figure.

12 CIRCUIT OPERATIONS
Note: The circuit diagram may be modified at any time with the development of new technology.
12.1. Telephone Line Interface and Pulse Dial Circuit
When the hook switch SW1 is ON (off-hook), the circuit is closed, and current is supplied to the base of Q2 via the diode bridge
D1 and Q2 is On →Q1 is ON (OFF-HOOK condition).
Q1 and Q2 are the dial pulse generating circuits, and are driven by the DIALER (IC1), when the DIALER Pin 11 of IC1 is LOW →
Q2 is OFF and Q1 is OFF. (break) If port Pin 11 is HIGH →Q2 is ON →Q1 is ON. (make)
12.2. Tone Dial Circuit
Function:
The tone dialing circuit consists of a DTMF (Dual Tone Multi Frequency) signal generator (outputted from Pin 12 of the IC1) for
tone dialing, and also a circuit for outputting the signal to line.
The DTMF circuit identifies inputs from the 12 keys (1,2,3,4,5,6,7,8,9,0, and #) by means of a total of seven frequencies, that
is four low frequencies (Low group) and three high frequencies (High group).
Circuit Description:
When a dial key is pressed, a DTMF signal is output from Pin 12 of IC1 as an analog synthetic wave.
The signal flow to the line is as follows.
Pin 12 of IC1 →R37 →Q9 →Q3 →Q1 →Tel Line.
The DTMF signal is sent to the line via the following path. Q9 and Q3 is an amplifier which is used to output the signal to line.
Shown below is the signal flow used to output the DTMF signal from the handset as a monitor tone when a dial key is pressed.
Pin 12 of IC1 →R48 →C33 →Q7 →C18 →Handset Speaker.
The signal combination and frequency corresponding to each dial key is shown on next page.

KX-TS3MXB / KX-TS3MXF / KX-TS3MXP / KX-TS3MXR / KX-TS3MXW

12.3. Ringer Circuit
Circuit Operation:
The bell signal passes through C1 (R1) →supplying power to pin 1 of IC2.
The ring signal is output from Pin 5 of IC2, and its volume is adjusted in 3 steps (H-L-OFF) by SW3 then impressed on the
ceramic sound generator, and so is generated.
Output frequency is controlled by R2 and C3 following below formula.
12.4. Power Circuit and Redial Back-up Circuit
Function:
This set is powered from the line. When it is an OFF-HOOK status, Tel Line →D1 →Q1 →R9 →pin 14 of IC1 (to become
the power supply for IC1 speech network).
The voltage from the line is turned into a constant voltage by D6 and then supplied to the IC1 and sending and receiving circuit
of the set.
At ON-HOOK status the voltage from the line via R40, R5 is turned into a constant voltage by D8, and then become power
supply for IC1 (Pin14), and the redial Back-up will be done.
12.5. Sending Circuit (Tx)
When a person talk through the Handset, the voice analog signal flow from the
mic →C20 →R33 →Q9 →R38 →C23 →Q3 →Q1 →D1 →Tel line.
* Q9 and Q3 is an amplifier for the voice signal.
12.6. Receiving Circuit (Rx)
Receiving signal from the line go through
D1 →Q1 →R15 →Q4 →R19 →C16 →JP8 →C17 →R26 →Q7 →C18 →R29 →Handset speaker.
* Q4 is amplifier for the Receiving signal.
