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 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 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 with
temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case of using high temperature soldering iron, please
be 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 possible
and 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 the
opposite side (See the figure below).
1.1.
Suggested PbF Solder
There 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
manufacturer’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.

Registering a Handset to a Base Unit
To Register an Additional Handset to a Base Unit (Easy Registration)
The included handset and base unit are preregistered. After purchasing an additional handset, register it to the base unit.
for few seconds to turn the handset on.
Ensure that the additional handset is switched on. If it is not on, press and hold
Note:
· If an error tone sounds, or if
is still flashing, register the handset manually (manual registration).
· If all registered handsets start ringing in step 2, press
to stop. Start again from step 1.
· Charge the batteries of your additional handset for about 7 hours before initial use.
· This registration method cannot be used for handsets that have already been registered to a base unit. Register the handset
manually (manual registration).
To Register a Handset to an Additional Base Unit (Manual Registration)
You can register a handset to a base unit manually using the following method.
8.5.1.
Cancelling a Handset
A maximum of 6 handsets can be registered to a base unit. A handset can cancel its own registration (or the registration of
another handset) that is stored in the base unit. This will allow the base unit to “forget” the handset.
26
8.5.2.
Cancelling a Base Unit
A handset can be registered to a maximum of 4 base units. A handset can cancel a base unit that it is registered to. This allows
the handset to “forget” the base unit.
Note:
To register the handset to another base unit or to the same base unit again, see manual registration.
8.6.
Selecting a Base Unit
When “
” is selected, the handset will automatically use any available base unit it is registered to. When a specific base
unit is selected, the handset will make and receive calls using that base unit only. If the handset is out of range of that base unit,
no calls can be made.

16.2. Troubleshooting for Speakerphone
When the customer’s telephone line corresponds to the following conditions, and the transmission signal of SP-Phone is
interrupted, performing the next set up to a cordless handset will improve it to some extent.
Conditions
1. When customer’s line has less line loss.
ex.) The customer is using optical fiber, ISDN terminal adaptor, or PBX.
In this case, receiving signal is strong and it may affect transmission signal.
2. When the other party is talking from noisy place.
ex.) The other party is using cellular phone. The background noise is very loud.
In this case, the noise from the other party (i.e. surrounding noise) may affect transmission signal.
Setting Method
· Change the address of EEPROM (0×0144) from 0×00 to 0×01.

Fig.101. The power supply is as follows;
· DECT BBIC (IC8):
CN1 (+6V) → D1 → IC1 → Q2 → IC8
· RF Module (IC2):
CN1 (+6V) → D1 → IC1 → Q2 → IC2 (PLL)
CN1 (+6V) → D1 → IC1 → IC2 (Power AMP)
· EEPROM (IC3):
CN1 (+6V) → D1 → IC1 → Q2 → IC3

CN1 (+6V) → D1 → R3, R5 → TP15
<Fig.101>
72
22.3. Telephone Line Interface
<Function>
· Bell signal detection
· Clip signal detection
· ON/OFF hook circuit
· Audio circuits
· DTMF tone signal circuits
Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection:
In the standby mode, Q4 is open to cut the DC loop current and decrease the ring load.
When ring voltage appears at the TP2 (A) and TP3 (B) leads (when the telephone rings), the AC ring voltage is transferred as
follows;
· A → C13 → R17 → R24 → IC8 Pin 60 (CID INp)
· B → C12 → R16 → R32 → IC8 Pin 52 (CID INn)
ON/OFF hook circuit:
In the standby mode, Q4 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit is
consequently in an off-hook condition.
When IC2 detects a ring signal or press the TALK Key onto the handset, Q5 turns on and then Q4 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 → D3 → Q4 → Q8 → R45 → R46 → D3 → B [OFF HOOK]
22.4. Transmitter/Receiver
Base 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.77).
22.4.1. Transmitter Block
The voice signal input from the TEL LINE interface goes to RF Module (IC2) through DECT BBIC (IC8) as shown in BLOCK
DIAGRAM (BASE UNIT) (P.70)
The voice signal passes through the analog part of IC8 where it is amplified and converted to a digital audio stream signal. The
burst switch controller processes this stream performing encryption and scrambling, adding the various other fields to produce
the GAP (Generic Access Profile) standard DECT frame, assigning to a time slot and channel etc.
In IC2, the carrier frequency is changing, and frequency modulated RF signal is generated and amplified, and radiated from
antenna. Handset detects the voice signal or data signal in the circuit same as the following explanation of Receiver Block.
22.4.2. Receiver Block
The signal of 19.2 MHz band (18.81792 MHz ~ 18.97344 MHz) which is input from antenna is input to IC2 as shown in BLOCK
DIAGRAM (BASE UNIT) (P.70).
In IC2, the signal of 19.2 MHz band is downconverted to 864 kHz signal and demodulated, and goes to IC8 as GAP (Generic
Access Profile) standard DECT frames. It passes 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 is amplified by the analog front end, and goes to the TEL LINE Interface.

· DECT BBIC (Base Band IC): IC1
− All data signals (forming/analyzing ACK or CMD signal)
− All interfaces (ex: Key, Detector Circuit, Charge, DC/DC Converter, EEPROM, LCD)
· RF Module: CN6
− PLL Oscillator
− Detector
− Compress/Expander
− Amplifier for transmission and reception
· EEPROM: IC3
− Temporary operating parameters (for RF, etc.)
24.2. Power Supply Circuit/Reset Circuit
Circuit Operation:
When power on the Handset, the voltage is as follows;
BATTERY(2.2 V ~ 2.6 V: J1) → L1, D1 → Q2 (1.8 V), Q3 (2.5 V), Q1 (3.3 V)
The Reset signal generates IC1 (53 pin) and 1.8 V.
24.3. Charge Circuit
Circuit Operation:
When charging the handset on the Base Unit, the charge current is as follows;
DC+(5.5V ~ 6V) → D1 → R4, R5 → CHARGE+(Base) → CHARGE+(Handset) → L4 → Q4 → D7→ F1 → BATTERY+...
Battery... BATTERY- → R43 → GND → L5 → 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 Q5 of Handset.
Refer to Fig.101 in Power Supply Circuit (P.72).
24.4. Battery Low/Power Down Detector
Circuit 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)
2.25V ± 50mV
The BBIC detects this level and "
" starts flashing.
· Power Down
Battery voltage: V(Batt)
2.0V ± 50mV
The BBIC detects this level and power down.
Refer to Check Point (Handset) (P.60).

30 HOW TO REPLACE THE FLAT PACKAGE IC
Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount),
a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
30.1. 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)
30.2. FLAT PACKAGE IC REMOVAL PROCEDURE
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 land 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.
88
30.3. FLAT PACKAGE IC INSTALLATION PROCEDURE
1. 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.
30.4. BRIDGE MODIFICATION PROCEDURE
1. Lightly resolder the bridged portion.
2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.
