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 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 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).

Signal Flowchart in the Radio Parts
Reception
A voice signal from TEL line is encoded to digital data "TXDATA" by DSP (IC501) in a base unit.
Then TXDATA goes to RF PART, and it's modulated to 1.9 GHz. The RF signal is amplified and fed to a selected antenna.
As for a handset RF, RF signal is received in two antennas.
RFIC (IC701) compares RF signal levels and selects the antenna to be used. Then RFIC down-converts to 864 kHz IF signal
from RX signal in the selected antenna, and demodulates it to digital data "RXDATA".
DSP (IC501) converts RXDATA into a voice signal and outputs it to speaker.

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 → 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 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.

4.4.6.
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 0.2 V 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.

4.4.7.
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, 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 when
the voltage changes by 0.2 V or more.

4.4.8.
Calling Line Identification (Caller ID)/Call Waiting Caller ID
Function:
Caller ID
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 data for the caller ID from the telephone exchange is sent during the interval between the
first and second rings of the bell signal. The data from the telephone exchange is a modem signal which is modulated in an FSK
(Frequency Shift Keying) * format. Data "1" is a 1200 Hz sine wave, and data "0" is a 2200 Hz sine wave. There are two types of
the message format which can be received: i.e. the single message format and plural message format. The plural message format allows to transmit the name and data code information in addition to the time and telephone number data.
*: Also the telephone exchange service provides other formats.

Call Waiting Caller ID
Calling Identity Delivery on Call Waiting (CIDCW) is a CLASS service that allows a customer, while off-hook on an existing call,
to receive information about a calling party on a waited call. The transmission of the calling information takes place almost
immediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the new
call.
Function:
The telephone exchange transmits or receives CAS and ACK signals through each voice RX/TX route. Then FSK data and
MARK data pass the following route.
Telephone Line → CN101 (T, R) → P101 → L101, L102 → C121, C122 → R121, R122 → IC501 (89, 88).
If the unit deems that a telephone connected in parallel is in use, ACK is not returned even if CAS is received, and the information for the second and subsequent callers is not displayed on the portable handset display.

Charge Circuit
When the handset is put on the cradle of the base unit, the power is supplied from CHARGE+ and CHARGE- terminals to
charge the battery via R366 or Q361. The voltage between CHARGE+ and CHARGE- flows Q531 → pin 38 of IC501, where
the charge is detected. Then IC501 calculates the battery consumption amount from the previous charge, and it controls Q361/
Q362/Q364 by pin 42 of IC501 until charging is complete. When charging is complete, the control pattern is switched to Trickle
charging form from Operational charging form.

4.7.5.
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 R436/R437 detects 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.
4.7.6.
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.
4.8.1.
Power Supply Circuit
As indicated below, the various voltages are supplied to each block.
V_PA, about 3.2 V at base unit or 3.1 V at handset, is supplied to the Power amplifier.
IC741 is 3.0 V at base unit or 2.7 V at handset Regulator and outputs VRF (3.0 V at base unit or 2.7 V at handset) by order of
RADIO_EN signal.
V_RF is approximately 4.0 V (Base Unit) or 3.1 V (Handset).

4.9.
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 7hours is started soon after the handset is placed on the charger unit. Then it changes to Trickle charge to prevent from overcharging.
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(-).

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.
