1 Safety Precaution
1.1.
For Service Technicians
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 Warning
2.1.
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 manufacture’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 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).

4.1.
4.1.1.
FHSS Description
Frequency
The frequency range of 2.4 GHz - 2.48 GHz is used. Transmitting and receiving channel between Base Unit and Handset is same
frequency. Refer to Frequency Table (P.81).
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 telephone system that can use multiple portable unit simultaneously. The explanation of this system is mentioned below. This system 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 the
Base Unit, total 8 slots in 10ms. By this slot system, simultaneous air link and communication between 4 Handsets and the Base
Unit 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 reduce
power density per time and per band. On the other hand, FHSS makes spectrum spread by changing channel every 10ms
according to Hopping table. Also the purpose to make spectrum spread is to reduce power density per time andper band.

4.1.2.1.
TDD Frame Format
Sync Field (72bit): Preamble 56bit + SyncWord 16bit
Base Unit (Handset) adjusts the timing of reception so that reception of Base Unit (Handset) can correspond to transmission of
Handset (Base Unit).
It is necessary for sync-field that Handset gets synchronization.
A - field (64bit): Each kinds of DATA: ch data, line condition, etc.
B - field (320bit + 80bit): Sound data + parity
Z - field (4bit): Parity Check
4.1.2.2.
TDMA system
This system is the cycles of 10ms, and has four duplex paths,
so it is possible to perform four duplex communications simultaneously.
In 1 slot 1.25ms, the 10ms of voice data is transmitted.
Each slot makes every frame frequency hop. (100hops/sec.)
Although each slot (UpLink3 and UpLink4) uses different frequency, UpLink3 and DownLink3 use the same frequency.
• 2 - Handsets Link
Traffic Bearer
A link is established between Base Unit and Handset.
The state where duplex communication is performed.
The hopping pattern of a 1800hops (18 seconds) cycle.
Dummy Bearer
The 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 System
Reception
CN101 of the Base Unit is connected to the TEL line, and signal is entered through the bridge diode D101. While talking, the
relay (Q141) is turned ON and amplified at the Q171, then led to DSP (IC501). The DSP encodes ADPCM and TDD/TDMA with
FHSS to TX-DATA. The TX-DATA signal is entered to IC701 of RF UNIT, and modulated to 2.4 GHz. The RF signal is fed into
Tx/Rx switch (D704). The RF signal is passed through filter (FL701) and fed to ANTENNA.
As for the Handset, RF signal from the antenna passes through filter (FL701), then is routed by Tx/Rx switch (D704) and led to
IC701. The RF signal is amplified by LNA and down-converted to IF signal in IC701. The IF signal passing through internal filter
is demodulated into RX-DATA, then enters DSP (IC501). The DSP performs TDD/TDMA and ADPCM decoding to convert the
RX-DATA into the voice signal, then it is output to the speaker.
Transmission
The voice signal entering from the microphone is led to DSP (IC501). The DSP encodes ADPCM and TDD/TDMA with FHSS to
TX-DATA. The TX-DATA signal enters IC101 of RF UNIT, and is modulated to 2.4 GHz. The RF signal is fed into Tx/Rx switch
(D704). The RF signal is passed through filter (FL701) and fed to ANTENNA.

4.5.5.
Telephone Line Interface
Telephone 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 through
the circuit). Following signal flow is the DC current flow.
T → L101 → D101 → Q141 → Q161 → R163 → 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 onhook 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 is
canceled by the canceller circuit of DSP.

Auto Disconnect Circuit
Function:
This circuit is used to detect the fact that another telephone connected to the same line is OFF-HOOK while the unit is in a
receiving 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 0.2V or more. When the set detects the parallelconnected telephone is OFF HOOK status, the line is disconnected.
You can enable or disable the Auto Disconnect function.
See Check Record (P.57)

4.5.7.
Parallel Connection Detect Circuit
Function:
In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have a
circuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone connected 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 Q136 is ON, 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 Q136 is OFF, the voltage is monitored at pin 90 of IC501; the presence/absence of a parallel connection is determined when the voltage changes by 0.2 V or more.

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 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 Caller-ID data from exchange is supplied to the telephone using either method of FSK or DTMF. The method is chosen
according to the exchange of telephone office. This unit is available to receive the data with both methods and displays the
received data on LCD.
FSK (Frequency Shift Keying) format
DTMF format
It is the method to send the telephone number of calling party with DTMF to the telephone. DTMF is sent before the first bell signal.
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 and 941
Hz) as the start code and end code according to the exchange.

Charge Circuit
When the Handset is put on the cradle of the Base unit or the charger, the power is supplied from CHARGE+ and CHARGE- terminals to charge the battery via D361 and R366 or Q361. The voltage between CHARGE+ and CHARGE- flows R531 → Q531
→ pin38 of IC501, where the charge is detected. Then IC501 calculates the battery consumption amount from the previous
charge, and it controls Q361/Q362/Q363 by pin80 of IC501 until charging is complete. When charging is complete, the control
pattern is switched to Trickle charging form from Operational charging form.

4.8.5.
Sending Signal
The voice signal from the microphone is input to DSP (90, 91). CN431 is the headset jack. When the headphone is connected,
the Q431 detect it. The input from the microphone of the Handset (MIM, MIP) is cut and the microphone signal from the headset
is input to DSP (95). Also the power for the microphone is supplied from DSP (92) and the power is turned OFF on standby.
4.8.6.
Reception Signal
The voice signal from the Base Unit is output to DSP (98). This signal is led to the headset jack (CN431). The signal through the
headset jack and the other signal output from DSP (97) drives the speaker. When the headset is inserted to the jack, the voice
signal is cut at the jack, so the sound does not come out from the speaker, but from the headset only.

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

2.4GHz Mod/Demod Circuit (Base Unit RF Part)
IC701 incorporates all of the modulation and demodulation functions. TX Digital data (TX_DATA) from DSP is supplied to pin 27 of
IC701, and then 2.4 GHz TX modulated signal is output from pin1. This TX signal is filtered by BPF (FL701) and supplied to
Antenna. 2.4 GHz RX signal from the Antenna is filtered by BPF (FL701) and supplied to pin4 of IC701, then demodulated signal
(RX_DATA) comes out from pin 16. At the same time, RSSI (Received Signal Strength Indicator) outputs from pin 14. Reference
clock (13.824 MHz) from DSP block is supplied to pin 11 of IC701. V_PA and V_RF supply 2.5V regulated voltage.
Note:
The exposed GND_PLATE on the bottom of the IC701 supplies the circuit ground(s) for the entire chip. It is very important that
a good solder connection is made between this GND_PLATE and the ground plane of the PCB underlying the IC701.

4.10. Circuit Operation (Charger Unit)
The voltage from the AC adaptor is supplied to the charge circuits. Main charge (180~250mA at the Battery) of maximum 7hours is started soon after the Handset is placed on the Charger Unit. Then it changes to Trickle charge to prevent from overcharging.
The route for this is as follows: DC + pin of CN1 → R1 ~ R5, R7 ~ R13 → CHARGE + pad → Handset → CHARGE-pad → DCpin of CN1.

10.2. How to Replace the Flat Package IC
10.2.1. 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.
• 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 board 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.

10.3.2. 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.
10.3.3. How to Remove the IC
1. 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 the P. C.
board.
3. After removing the IC, clean the P. C. board of residual solder.
