1 Safety Precautions
1.1. For Service Technicians
• Repair service shall be provided in accordance with repair technology information such as servic e manual so as to prevent 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.
2Warning
2.1. Battery Caution
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
Attention:
A nickel metal hydride battery that is recyclable powers the product you have purchased. 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, pl ease check the component side for excess which may flow onto the opposite side (See the figure below).

•B  P101  C104  R102  IC501 (CID INp)
C106 R104 
•A  C103  R101  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 fl ow makes the loop current.
•B  P101 D101  Q141  Q161  R163  D101  A
4.4.6. 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.19).
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 (1921.536 MHz ~ 1928.448 MHz) 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.
15
KX-PRW130W/KX-PRWA13W
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 bein g used. T he dat a for the call er ID fr om 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, R10 5, 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.

8.2. EEPROM LAYOUT (Handset)
8.2.1. Scope
The purpose of this section is to describe the layout of the EEPROM (IC3) for the KX-PRWA13 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. This document lists all default parameters with a short description.
