Please call 1-800-8-BATTERY (1-800-822-8837) for information on how to recycle this battery.
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).
Remove all of the
excess solder

• Bell signal detection
• Clip signal detection
• ON/OFF hook circuit
Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection:
In the standby mode, Q141 is open to cut the DC loop current and decrease the ring load.
When ring voltage appears at the L1T (A) and L1R (B) leads (when the telephone rings), the AC ring voltage is transferred as
follows;
• B → P101 → C106 → R106 → R107 → IC501 (CID INp)
• A → C105 → R105 → R108 → IC501 (CID INn)
ON/OFF hook circuit:
In the standby mode, Q104 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit is
consequently in an on-hook condition.
When IC501 detects a ring signal or press the TALK Key onto the handset, Q142 turns on and then Q141 turns on, thus
providing an off-hook condition (DC current flows through the circuit) and the following signal flow makes the loop current.
• B → P101 →D101 → Q141 → Q161 → R163 → D101 → A

Transmitter/Receiver
• Audio Circuits and DTMF tone signal circuits.
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.20).
4.4.6.1.
Transmitter Block
The voice signal input from the TEL LINE interface goes to DECT BBIC (IC501) as shown in Block Diagram (Base Unit) (P.10)
The voice signal passes through the analog part of IC501 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 IC501, the carrier frequency is changing, and frequency modulated RF signal is generated.In IC501,RF signal is amplified,
and radiated from antenna. Handset detects the voice signal or data signal in the circuit same as the following explanation of
Receiver Block.
4.4.6.2.
Receiver Block
The signal of 1900 MHz band (1921.536MHz ~ 1928.448MHz) which is input from antenna is input to IC501 as shown in Block
Diagram (Base Unit) (P.10).
In IC501, the signal of 1900 MHz band is downconverted to 864 kHz signal and demodulated, 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.
4.4.7.
WiFi Module
BBIC and WiFi module are connected with 3group signals as shown in Block Diagram (Base Unit) (P.10).
SPI (Serial Peripheral Interface) Control --- Control the data (except Audio data) between BBIC and Wi-Fi module
Interrupt Control --- Control the timing of sending/receiving of BBIC and Wi-Fi module
PCM (Pulse Code Modulation) Control --- Control the Audiol data between BBIC and Wi-Fi module.
When turning ON, it start to communicate between BBIC and WiFi module by SPI Control with Interrupt control to set various
data into the register of WiFi module and then it becomes Stand-by status.
WiFi network data, such as MAC address is transferred to Memory of WiFi module from BBIC's one.
For talk with Smartphone via WiFi, audio signal is modified to PCM signal then communicated.
4.4.8.
Parallel Connection Detect Circuit/Auto Disconnect 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 (N1), (N2) of IC501. There is no parallel connection if the voltage is
0.54 V or higher, while a parallel connection is deemed to exist if the voltage is lower.
14
KX-PRW120W/KX-PRWA10W
Parallel connection detection when off hook:
When off hook, the voltage is monitored at pin (F2) of IC501; the presence/absence of a parallel connection is determined by
detecting the voltage changes.
If the Auto disconnect function is ON and statuses are Hold, receiving ICM, OGM transmitting, BBIC disconnects the line after
detecting parallel connection is off hook.
4.4.9.
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 → P101 → C103, R101, C105, R103, C107, R105, C104, R102, C106, R104, C108, R106 → IC501 (H2, H1).
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 display.

EEPROM LAYOUT (Handset)
Scope
The purpose of this section is to describe the layout of the EEPROM (IC3) for the KX-PRWA10 Handset.
The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of the
handset, some are set by the user when configuring the handset, and some during normal use of the phone.
8.2.2.
Introduction
The handset uses a 64k bit serial EEPROM (IC3) for storing volatile parameters. All parameters are set up before the handset
the factory. Some of these are vital for the operation of the hardware so a set of default parameters is programmed before the
actual hardware fine-tuning can be initiated. This document lists all default settings with a short description.

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.

12.1. 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.
12.1.1. 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.5)
12.1.2. 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.
65
KX-PRW120W/KX-PRWA10W
12.1.3. How to Install the IC
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.
12.1.4. How to Remove a Solder Bridge
1. Lightly resolder the bridged portion.
2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.
66
KX-PRW120W/KX-PRWA10W
12.2. How to Replace the Shield Case
12.2.1. 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.
• Hot Air Desoldering Tool
Temperature: 608 °F ± 68 °F (320 °C ± 20 °C)
12.2.2. 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.
12.2.3. How to Remove the Shield Case
Note:
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.
