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 lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced. 3. 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 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 manufacturer's 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 50°F ~ 70° F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with temper-

ature 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).

5


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 manufac-turer's specific instructions for the melting points of their products and any precautions for using their product with other materi-als. The following 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 Technical Descriptions4.1. FHSS Description4.1.1. FrequencyThe frequency range of 5.76 GHz-5.84 GHz is used. Transmitting and receiving channel between base unit and handset is samefrequency. Refer to Frequency Table (P.77).

4.1.2. FHSS (Frequency Hopping Spread Spectrum)This telephone is using an IC chip which has similar specification to WDCT (World Digital Cordless Telephone) and is the tele-phone system that can use multiple portable unit simultaneously. The explanation of this system is mentioned below. This sys-tem uses a Time Division Multiple Access/Time Division Duplex (TDMA/TDD) scheme:transmitting and receiving frequencies of the base unit and handset are shared in the same frequency. The construction of RX/TX frequency data is shown below. It consists of 4 slots from the base unit to the handset, and 4 slots from the handset to thebase unit, total 8 slots in 10 ms. By this slot system, simultaneous air link and communication between 4 handsets and the baseunit can be realized. One communication between handset and the base unit is done by one slot from the base unit to handset,and another slot from handset to the base unit.DSS makes spectrum spread by multiplying carrier signal by PN code. The purpose to make spectrum spread is to reducepower density per time and per band. On the other hand, FHSS makes spectrum spread by changing channel every 10 msaccording to Hopping table. Also the purpose to make spectrum spread is to reduce power density per time and per band.

4.1.2.1. TDD Frame Format

Sync Field (72 bit): Preamble 56 bit + SyncWord 16 bitBase unit (handset) adjusts the timing of reception so that reception of base unit (handset) can correspond to transmission ofhandset (base unit). It is necessary for sync-field that handset gets synchronization.A - field (64 bit): Each kinds of DATA: ch data, line condition, etc.B - field (320 bit + 80 bit): Sound data + parityZ - field (4 bit): Parity Check

4.1.2.2. TDMA systemThis system is the cycles of 10 ms, and has four duplex paths, so it is possible to perform four duplex communications simultaneously.In 1 slot 1.25 ms, the 10 ms of voice data is transmitted.Each slot makes every frame frequency hop. (100 hops/sec.)Although each slot (UpLink3 and UpLink4) uses different frequency, UpLink3 and DownLink3 use the same frequency.

• 2 - Handsets Link

Traffic BearerA link is established between base unit and handset.The state where duplex communication is performed.The hopping pattern of a 3000 hops (30 seconds) cycle.

Dummy BearerThe base unit sends Dummy-data to the all stand-by state handsets. The handsets receive that data for keeping synchronization and monitoring request from the base unit. Dummy Bearer doesn't contain B-field (sound) data.

4.1.3. Signal Flowchart in the Whole SystemReception

TEL JACK of the base unit is connected to the TEL line, and signal is input through the bridge diode D101. While talking, therelay (Q141) is turned ON and amplified at the Q171, then led to DSP (IC501). The DSP encodes ADPCM and TDD/TDMA withFHSS to TXDATA. The TXDATA signal goes into IC701 of RF PART, and is modulated to 5.8 GHz. The RF signal is amplified bythe power amplifier (IC801) and fed to Antennas.

As for the handset, RF signal from the RX antenna is amplified by LNA (IC801). The amplified signal is down-converted to IFsignal in IC701. The IF signal passing through internal filter is demodulated into RXDATA, then goes into DSP (IC501). The DSPperforms TDD/TDMA and ADPCM decoding to convert the RXDATA into the voice signal, then it is output to the speaker.

TransmissionThe voice signal entering from the handset microphone is led to DSP (IC501). The DSP encodes ADPCM and TDD/TDMA withFHSS to TXDATA. The TXDATA signal goes into IC701 of RF PART, and is modulated to 5.8 GHz. The RF signal is amplified bythe power amplifier (IC801) and fed to Antenna.

As for the base unit, RF signal from the Antennas is amplified by LNA (IC801). The amplified signal is down-converted to IF sig-nal in IC701. The IF signal passing through internal filter is demodulated into RXDATA, then goes into DSP (IC501). The DSPperforms TDD/TDMA and ADPCM decoding to convert the RXDATA into the voice signal. The voice signal is amplified at the TXamplifier (Q161), then output to the TEL line TEL JACK through the relay (Q141) and bridge (D101).

4.5. Circuit Operation (Base Unit)General Description:

(DSP, Flash Memory) is a digital speech/signal processing system that implements all the functions of speech compression,record and playback, and memory management required in a digital telephone answering machine.The DSP system is fully controlled by a host processor DSP. The host processor provides activation and control of all that func-tions as follows.

4.5.1. DSP (Digital Speech/Signal Processing: IC501)• Voice Message Recording/Play back

The DSP system uses a proprietary speech compression technique to record and store voice message in Flash Memory.An error correction algorithm is used to enable playback of these messages from the Flash Memory.

• DTMF Detection/GeneratorThe DTMF detection is implemented by the DSP system in software. The DTMF detection is performed during Line Monitoringmodes of operation.When the DTMF data from the handset is received, the DTMF signal is output..

• Synthesized Voice (Pre-recorded message)The DSP implements synthesized Voice, utilizing the built in speech detector and a Flash Memory, which stored the vocabulary.

• Caller ID demodulationThe DSP implements monitor and demodulate the FSK signals that provide CID information from the Central Office.

• Digital SwitchingThe voice signal from telephone line is transmitted to the handset or the voice signal from the handset is transmitted to the Tele-phone line, etc. They are determined by the signal path route operation of voice signal.

• Block Interface CircuitRF part, LED, Key scan, Speaker, Microphone, Telephone line.

4.5.2. Flash Memory (IC601)Following information data is stored.

• Voice signalex: Pre-recorded Greeting message, Incoming message

• Settingsex: message numbers, ID code, Flash Time, Tone/Pulse

14


4.5.3. Power Supply CircuitFunction:

The power supply voltage from AC adaptor is converted to the desired voltage of each block.Circuit Operation:

• Q300 and IC300: 4.0 V DCDC Converter• IC331: 3.3 V Regulator

15


4.5.3.1. Charge CircuitThe voltage from the AC adaptor is supplied to the charge circuits.

16


4.5.4. Reset CircuitFunction:

This circuit is used to initialize the microcomputer when it incorporates an AC adaptor.Circuit Operation:

When the AC Adaptor is inserted into the unit, then the voltage is shifted by IC331 and power is supplied to the DSP.The set starts to operate when VCC goes up to 3.0 V or more in the circuit voltage diagram.

Note:(*1) The initializing time of the DSP chip is 28 ms under normal conditions.

17


4.5.5. Telephone Line InterfaceTelephone 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 → DSP pin 58 [BELL]When the CPU (DSP) detects a ring signal, Q141 turns on, thus providing an off-hook condition (active DC current flow throughthe 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 on-hook condition.

Pulse Dial Circuit:Pin 59 of DSP 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 iscanceled by the canceller circuit of DSP.

18


4.5.6. Auto Disconnect CircuitFunction:

This circuit is used to detect the fact that another telephone connected to the same line is OFF-HOOK while the unit is in areceiving status or OGM transmitting status.

Circuit Operation:The voltage of pin 90 of IC501 is monitored. If a parallel-connected telephone is put into OFF HOOK status, the presence/absence of a parallel connection is determined when the voltage changes by 0.2 V or more. When the set detects the parallel-connected telephone is OFF HOOK status, the line is disconnected.

You can enable or disable the Auto Disconnect function.See Check Record (P.57)

19


4.5.7. Parallel Connection Detect CircuitFunction:

In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have acircuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone con-nected 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 86 of IC501. There is no parallel connection if the voltage is 1.65 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 90 of IC501; the presence/absence of a parallel connection is determined whenthe voltage changes by 0.2 V or more.

20


4.5.8. Calling Line Identification (Caller ID)Function:

The caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone companyto utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has beenentered for the circuit being used.The Caller-ID data from exchange is supplied to the telephone using either method of FSK or DTMF. The method is chosenaccording to the exchange of telephone office. This unit is available to receive the data with both methods and displays thereceived data on LCD.

• FSK (Frequency Shift Keying) format

• DTMF formatIt is the method to send the telephone number of calling party with DTMF to the telephone. DTMF is sent before the first bell sig-nal. The data is sent in turn; first the start code, secondly the telephone number of calling party, lastly end code.The DTMF is chosen from A (1633 Hz and 697 Hz), B (1633 Hz and 770 Hz), C (1633 Hz and 852 Hz) and D (1633 Hz and941Hz) as the start code and end code according to the exchange.

4.8.5. Sending SignalThe voice signal from the microphone is input to DSP (90, 91). Also the power for the microphone is supplied from DSP (92) andthe power is turned OFF on standby.

4.8.6. Reception SignalThe voice signal from the base unit is output from DSP (97,98) drives the speaker.

27


4.9. Circuit Operation (RF Part)General Description:

RF part includes Transmitter and Receiver functions. Digital signals (Mainly voice data) that come from DSP, are modulated andare transmitted. On the other hand, received signals are demodulated and go out to DSP.

4.9.1. Power Supply CircuitAs indicated below, the various voltages are supplied to each block.V_PA, about 4.0 V at base unit or 3.3 V at handset, is supplied to the Power amplifier in 5.8 GHz PA circuit.IC761 is 3.0 V Regulator and outputs VRF (3.0 V) by order of RADIO_EN signal.V_RF is approximately 4.0 V (Base Unit) or 3.6 V (Handset).

28


4.9.2. 5.8 GHz Mod/Demod CircuitIC701 incorporates all of the modulation and demodulation functions.TX Digital data (TX_DATA) from DSP is supplied to pin 17 of IC701, and then 5.8 GHz TX modulated signals is output from pin 1. This 5.8 GHz TX signal goes into the PA circuit in IC801. On the other hand, amplified 5.8 GHz RX signal from LNA in IC801 is passed through BALUN (BALunce-UNbalunce) matching cir-cuit and supplied to pin 7 and pin 8.In IC701, RX signal is down-converted to 432 kHz IF signal, and demodulated, and RX digital data (RX_DATA) goes from pin 17 toDSP.

IC701 outputs some digital signals (PAEN, ANTSEL_A, ANTSEL_B, LNAEN, RXGAIN), and controls IC801.Reference Clock signal (13.824 MHz) is supplied to pin 25.

Note:The exposed GND_PLATE on the bottom of the IC701 supplies the circuit ground(s) for the entire chip. It is very important thata good solder connection is made between this GND_PLATE and the ground plane of the PCB underlying the IC701.

4.9.3. 5.8 GHz PA (Power Amplifier), 5.8 GHz LNA (Low Noise Amplifier) and AntennaSwitch Circuit

IC801 includes PA (Power Amplifier) block, LNA (Low Noise Amplifier) Block and Antenna Switch Circuit.

PA block amplifies 5.8 GHz TX signal.5.8 GHz TX signal from 5.8 GHz RF IC (IC701) is amplified by PA (Power Amplifier) block of IC801. After that, it is supplied toAntenna Switch block from pin 24 of IC801. V_PA is approximately 4.0 V at base unit, and 3.1 V at handset.LNA block amplifies receiving 5.8 GHz signal. 5.8 GHz RX signal from Antenna Switch block of IC801 is amplified by LNA block and is supplied to IC701.Antenna Switch block of IC801 switches for RF signals by ANTSEL_A and ANTSEL_B from IC701.IC701 checks RSSI (Received Signal Strength Indicator), and selects better receiving condition antenna.At RX mode, RX signal is lead from selected antenna to LNA block.On the other hand, 5.8 GHz TX signal from PA block is lead to selected antenna at RX mode.

Note:The exposed GND_PLATE on the bottom of IC801 supplies the circuit ground(s) for the entire chip. It is very important that agood solder connection is made between this GND_PLATE and the ground plane of PCB underlying the IC801.

4.10. Circuit Operation (Charger Unit)The voltage from the AC adaptor is supplied to the charge circuits. Main charge (180~250 mA at the Battery) of maximum 7-hours is started soon after the handset is placed on the charger unit. Then it changes to Trickle charge to prevent from over-charging.

Charging form

The route for this is as follows: DC+pin of J1(+) → F1 → D1 → R1 → CHARGE+pad → Handset → CHARGE-pad → DC-pin of J1(-).

13.4. How to Replace the Flat Package IC13.4.1. Preparation

• PbF (: Pb free) Solder• Soldering Iron

Tip Temperature of 700°F ± 20°F (370°C ± 10°C)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 withless experience could overheat and damage the PCB foil.

• FluxRecommended Flux: Specific Gravity → 0.82.Type → RMA (lower residue, non-cleaning type)Note: See About Lead Free Solder (PbF: Pb free) (P.4).

13.4.2. How to Remove the IC1. 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 board with some tools like a soldering wire. If some solder isleft at the joint on the board, the new IC will not be attached properly.

83


13.4.3. How to Install the IC1. 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.

13.4.4. How to Remove a Solder Bridge1. Lightly resolder the bridged portion.2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.

84


13.5. How to Replace the LLP (Leadless Leadframe Package) IC13.5.1. Preparation

• PbF (: Pb free) Solder• Soldering Iron

Tip Temperature of 700°F ± 20°F (370°C ± 10°C)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.

• Hot Air Desoldering ToolTemperature: 608°F ± 68°F (320°C ± 20°C)

13.5.2. Caution• To replace the IC efficiently, choose the right sized nozzle of the hot air desoldering tool that matches the IC package.• Be careful about the temperature of the hot air desoldering tool not to damage the PCB and/or IC.

13.5.3. How to Remove the Shield CaseNote:

If you don’t have special tools (ex. Hot air disordering tool), conduct the following operations.

1. Cut the case along perforation.

2. Remove the cut part.

3. Cut the four corners along perforation.

4. Remove the reminds by melting solder.

85


13.5.4. How to Install the Shield CaseNote:

• If you don’t have special tools (ex. Hot air disordering tool), conduct the following operations• Shield case’s No. : PNMC1001Z

1. Put the shield case.

2. Solder the surroundings.

13.5.5. How to Remove the IC1. Heat the IC with a hot air desoldering tool through the P.C.Board.

2. Pick up the IC with tweezers, etc. when the solder is melted completely.Note:

• Be careful not to touch the peripheral parts with tweezers, etc. They are unstable.

When it is hard to melt the solder completely, heat it with a hot air desoldering tool through the IC besides through theP.C.Board.

3. After removing the IC, clean the P.C.Board of residual solder.

86


13.5.6. How to Install the IC1. Place the solder a little on the land where the radiation GND pad on IC bottom is to be attached.

2. Place the solder a little on the land where IC pins are to be attached, then place the IC.Note:

• When placing the IC, the positioning should be done very carefully.

3. Heat the IC with a hot air desoldering tool through the P.C.Board until the solder on IC bottom is melted.Note:

• Be sure to place it precisely, controlling the air volume of the hot air desoldering tool.

4. After soldering, confirm there are no short and open circuits with visual inspection.

13.5.7. How to Remove a Solder BridgeWhen a Solder Bridge is found after soldering the bottom of the IC, remove it with a soldering iron.
