1 Safety Precautions1.1. For Service Technicians

• Repair service shall be provided in accordance with repair technology information such as service manual so as toprevent 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.

2 Warning2.1. 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 thatcontains 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 repairwork 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).

Transmitter BlockThe 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 toproduce 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 ofReceiver Block.

4.4.6.2. Receiver BlockThe signal of 1900 MHz band (1921.536MHz ~ 1928.448MHz) which is input from antenna is input to IC501 as shown in BlockDiagram (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 frameinformation and performs de-encryption and de-scrambling as required. It then goes to the DSP section where it is turned backinto analog audio. This is amplified by the analog front end, and goes to the TEL LINE Interface.

4.4.7. WiFi ModuleBBIC 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 moduleInterrupt Control --- Control the timing of sending/receiving of BBIC and Wi-Fi modulePCM (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 variousdata 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 CircuitFunction:

In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have acircuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephoneconnected 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


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 bydetecting the voltage changes.If the Auto disconnect function is ON and statuses are Hold, receiving ICM, OGM transmitting, BBIC disconnects the line afterdetecting parallel connection is off hook.

4.4.9. Calling Line Identification (Caller ID)/Call Waiting Caller IDFunction:

Caller IDThe caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone companyto utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has beenentered for the circuit being used. The data for the caller ID from the telephone exchange is sent during the interval between thefirst 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 ofthe message format which can be received: i.e. the single message format and plural message format. The plural messageformat 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 IDCalling 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 almostimmediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the newcall.

Function:The telephone exchange transmits or receives CAS and ACK signals through each voice RX/TX route. Then FSK data andMARK 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 theinformation for the second and subsequent callers is not displayed on the portable display.

12 Miscellaneous12.1. 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), asoldering 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 withless experience could overheat and damage the PCB foil.

• FluxRecommended 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 IC1. 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 isleft at the joint on the board, the new IC will not be attached properly.

66


12.1.3. How to Install the IC1. 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 Bridge1. Lightly resolder the bridged portion.2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.

67


12.2. How to Replace the Shield Case12.2.1. 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 ToolTemperature: 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 CaseNote:

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.

68


12.2.4. How to Install the Shield CaseNote:

• If you don’t have special tools (ex. Hot air disordering tool), conduct the following operations.• Shield case’s No. : PNMC1091Z, PNMC1033Z

1. Put the shield case.

2. Solder the surroundings.
