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 thatcontains 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 repairwork 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 withtemperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case of using high temperature soldering iron, pleasebe 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 possibleand 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 theopposite side (See the figure below).
1.1. Suggested PbF SolderThere 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.

20.3. Telephone Line Interface
· Bell signal detection
· Clip signal detection
· ON/OFF hook circuit
· Audio circuits
Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection:
In the standby mode, Q2 is open to cut the DC loop current and decrease the ring load.
When ring voltage appears at the TP3 (A) and TP40 (B) leads (when the telephone rings), the signal is transferred as follows;
· A → C4 → R2 → R29 → IC2 (DLP) [BELL & CLIP ]
· B → C3 → R1 → R30 → IC2 (DLN) [BELL & CLIP ]
ON/OFF hook circuit:
In the standby mode, Q2 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit isconsequently in an on-hook condition .
When IC2 detects a ring signal or press the TALK Key onto the handset, Q3 turns on and then Q2 turns on, thus providing anoff-hook condition (active DC current flow through the circuit) and the following signal flow is for the loop current.
· A → R77 → D2 → Q2 → R8 → Q3 → D2→ B [OFF HOOK]
20.4. Transmitter/ReceiverBase Unit and Handset mainly consist of RF Module and DECT BBIC.
Base Unit and Handset transmit/receive voice signal and data signal through the antenna on carrier frequency.
Signal Pass:
*Refer to SIGNAL ROUTE (P.64).
20.4.1. Transmitter Block
The voice signal input from the TEL LINE interface goes to RF Module (IC3) through DECT BBIC (IC2) as shown in BLOCKDIAGRAM (BASE UNIT) (P.57)
The voice signal passes through the analog part of IC2 where it is amplified and converted to a digital audio stream signal. Theburst switch controller processes this stream performing encryption and scrambling, adding the various other fields to producethe GAP (Generic Access Profile) standard DECT frame, assigning to a time slot and channel etc.
In IC3, the carrier frequency is changing, and frequency modulated RF signal is generated and amplified, and radiated fromantenna. Handset detects the voice signal or data signal in the circuit same as the following explanation of Receiver Block.
20.4.2. Receiver Block
The signal of 19.2 MHz band (18.81792 MHz ~ 18.97344 MHz) which is input from antenna is input to IC3 as shown in BLOCKDIAGRAM (BASE UNIT) (P.57).
In IC3, the signal of 19.2 MHz band is downconverted to 864 kHz signal and demoduleted, and goes to IC2 as GAP (GenericAccess Profile) standard DECT frames. It passes through the decoding section burst switch controller where it separates outthe frame information and performs de-encryption and de-scrambling as required. It then goes to the DSP section where it isturned back into analog audio. This is amplified by the analog front end, and goes to the TEL LINE Interface.
20.5. Pulse DialingDuring pulse dialing the hookswitch (Q2,Q3) is used to generate the pulses using the HOOK control signal, which is set highduring pulses. To force the line impedance low during the "pause" intervals between dialpulses, the PULSE_DIAL signal turnson Q7.

The Reset signal generates IC1,C58 and 2.65V.
22.3. Charge CircuitCircuit Operation:
When charging the handset on the Base Unit, the charge current is as follows;
DC+(5.5V ~ 6V) → D4 → R43, R44 → L4 → CHARGE+(Base) → CHARGE+(Handset) → Q7→ F1 → BATTERY+ ... Battery... BATTERY- → R14 → GND → CHARGE-(Handset)→ CHARGE-(Base) → GND → DC-(GND)
In this way, the BBIC on Handset detects the fact that the battery is charged.
The charge current is controlled by switching Q7 of Handset.
Refer to Fig.101 in Power Supply Circuit (P.59).
22.4. Battery Low/Power Down DetectorCircuit Operation:
"Battery Low" and "Power Down" are detected by BBIC which check the voltage from battery.
The detected voltage is as follows;
· Battery Low
Battery voltage: V(Batt) < 2.3V
The BBIC detects this level and " " starts flashing and "battery alarm" starts ringing.

27 EEPROM LAYOUT (BASE UNIT)27.1. Scope
The purpose of this section is to describe the layout of the EEPROM (IC1) for the KX-TCD450 Base Unit.
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of thebase e.g. crystal frequency adjustment at address 0000 and 0001, some are set by the user configuration e.g. ringer volumeat address 0220, and some are set during normal use of the phone e.g. meter pulse billing at address 0140..015F.
27.2. IntroductionThe base unit uses a 32K bit serial EEPROM (IC1) for storing volatile parameters. All parameters are set up before the baseleaves the factory. Some of these are vital for the operation of the hardware so a set of default parameters is programmedbefore the actual hardware fine-tuning can be initiated. This document lists all default settings with a short description.
In the tables below values in a range that are similar are not repeated; i.e. Address 00 to 01 contains the value 00 simply meansthat the value 00 is repeated in all addresses in the range. All values in this document are in hexadecimal notation.
Type Name DescriptionD default The EEPROM location is preset to the Default value by the eeprom default loader.A adjust The EEPROM location is set during the production test and should not be overwritten. The value is set by the
eeprom default loader only if the location contains all 1’s (byte: 0xFF, word FFFFh), i, e. it has never been set.- EEPROM location which is not set at all.d default Same as D but best-guess value and/or not verified.
