1 Safety Precautions1.1. For Service Technicians

Repair service shall be provided in accordance with repair technology information such as service manual so as to pre-vent 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 wiring unit is supplied as a repair part, the entire wiring unit shall be replaced, rather than repairing and connecting the

wires, even when only some of its wires are broken.3. FASTON terminals shall be plugged straight in and unplugged straight out, rather than jiggling them into or out of position.

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 Warning2.1. 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 manufactures 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 con-tains 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.

Caution PbF solder has a melting point that is 50F ~70F (30C ~ 40C) higher than Pb solder. Please use a soldering iron with temper-

ature control and adjust it to 700F 20F (370C 10C). 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 1100F (600C). 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).


2.2.1. 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 manufacturersspecific instructions for the melting points of their products and any precautions for using their product with other materials. Thefollowing 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. BoardWhen discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

4.2. Circuit Operation (Base Unit)4.2.1. Outline

Base Unit consists of the following ICs as shown in Block Diagram (Base Unit) (P.7). DECT BBIC (Base Band IC): IC3 (career module)

- Handling all the audio, signal and data processing needed in a DECT base unit- Controlling the DECT specific physical layer and radio section (Burst Module Controller section)- ADPCM codec filter for speech encoding and speech decoding (DSP section)- Echo-cancellation and Echo-suppression (DSP section)- Any tones (tone, sidetone, ringing tone, etc.) generation (DSP section)- DTMF receiver (DSP section)- Clock Generation for RF Module- ADC, DAC, timer, and power control circuitry- All interfaces (ex: RF module, EEPROM, LED, Analog Front End, etc.)- PLL Oscillator- Detector- Compress/Expander- First/Second Mixer- Amplifier for transmission and reception

EEPROM: IC1- Temporary operating parameters (for RF, etc.)

Additionally,- Power Supply Circuit (+3.3V, +2.6V output)- Crystal Circuit (20.736MHz)- Charge Circuit- Telephone Line Interface Circuit

4.2.2. Power Supply CircuitThe power is supplied to the DECT BBIC, RF Module, EEPROM, Relay Coil, LED and Charge Contact from AC Adaptor asshown in Fig.101. The power supply is as follows:


4.2.3. 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, Q3 is open to cut the DC loop current and decrease the ring load.When ring voltage appears at the BATTERY (+) and BATTERY (-) leads (when the telephone rings), the signal is transferred as fol-lows;

A C26 R33 R19, R31 R201 IC3 LINEA (DLP) [BELL & CLIP] B C27 R34 R16, R30 R200 IC3 LINEN (DLP) [BELL & CLIP]

ON/OFF hook circuit:In the standby mode, Q3 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit is consequentlyin an off-hook condition. When IC3 detects a ring signal or press the TALK Key onto the handset, Q2 turns on and then Q3 turns on, thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow is for the loop current.

A D2 Q3 Q1 R9 R10 D2 B [OFF HOOK]Audio circuits:Refer to Signal Route (P.12).

4.2.4. 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 Path:*Refer to Signal Route (P.12).

4.2.4.1. Transmitter BlockThe voice signal input from the TEL LINE interface goes to DECT BBIC (IC3) as shown in Block Diagram (Base Unit) (P.7)The voice signal passes through the analog part of IC3 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.

4.2.4.2. Receiver BlockThe signal of 1.9 GHz band (1.912896 GHz ~ 1.928448 GHz) which is input from antenna is input to IC3 as shown in Block Dia-gram (Base Unit) (P.7).In IC3, the signal of 1.9 GHz band is demodulated, and goes to IC2 as GAP (Generic Access Profile) standard DECT frames. Itpasses through the decoding section burst switch controller where it separates out the frame information and performs de-encryption and de-scrambling as required. It then goes to the DSP section where it is turned back into analog audio. This isamplified by the analog front end, and goes to the TEL LINE Interface.

4.3. Pulse DiallingDuring 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 dial pulses, the PULSE_DIAL signal turnson Q4.

9.3. Troubleshooting by Symptom (Handset)If your unit has below symptoms, follow the instructions in remedy column. Remedies depend on whether you have DECT tester(*1) or not.

Note:(*1) A general repair is possible even if you dont have the DECT tester because it is for confirming the levels, such as Acousticlevel in detail.(*2) Refer to Check Point (Handset) (P.31)

9.3.1. Check Point (Handset)Please follow the items below when BBIC or EEPROM is replaced.

Note:After the measuring, suck up the solder of TP.*: PC Setting (P.39) is required beforehand.The connections of simulator equipments are as shown in Adjustment Standard (Handset) (P.41).
