1 Safety Precautions1.1. For Service Technicians
• Repair service shall be provided in accordance with repair technology information such as service 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.
2 Warning2.1. 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 con-tains lead.We will use PbF 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° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron with tempera-
ture control and adjust it to 700° ± 20° F, (370° ± 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 figure, below).
2.1.1. Suggested PbF SolderThere 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.

2.1.2. Information for Users on Collection and Disposal of Old Equipment and used Bat-teries
2.2. Battery Caution1. 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 manufacture's Instructions.
2.3. Discarding of P. C. BoardWhen discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

• BBIC (Base Band IC): IC3- All data signals (forming/analyzing ACK or CMD signal)- All interfaces (ex: Key, Detector Circuit, Charge, LCD, LED, SRAM, Flash ROM)
• SRAM: IC1- Application data and code are temporarily stored.
• Flash ROM (substitute EEPROM): IC2- Source program data and temporary user data are stored.
• AMPLIFIER IC: IC5- Single OP_AMP for SPEAKER
• RF Module:- PLL Oscillator- Detector- Compress/Expander- Amplifier for reception- Amplifier for transmission
4.2.2. Power Supply Circuit/Reset CircuitWhen power on the Handset, the voltage is as follows;
BATTERY(3.5 V to 4.2V: Battery+) → Q8 (1.8V) → Q10 (3.0V)The reset signal is generated with IC3 and Q17.Power for RF IC (IC601) is generated with IC603.5.0V for LCD back-light is generated with IC4.Battery (3.5V to 4.2V) is used for RF Module, Amplifier IC (IC5), Vibrator, DC/DC Converter (IC4).1.8V is used only for BBIC (IC3).3.0V is used for BBIC (IC3), LCD, SRAM (IC1), Flash ROM (IC2), Red LED, Green LED, Key back-light.

4.2.5. TX Audio PathMicrophone
An audio signal from microphone is input to pin 118 (MIC+) of IC3 via headset jack (CN1).In IC3, the audio signal is converted from the analog signal to ADPCM, then to burst data, and sent from pin 28 (TXDA) to RFModule. The stabilized supply voltage is fed to the microphone from pin 119 (VREF+) of IC3.To reduce consumption current, this voltage is supplied only while calling or receiving.
HeadsetWhen a headset is inserted, a signal from microphone is cut off and an audio signal from a headset is input to pin 118 (MIC+).
Headset detectionWhen a headset is inserted, pin 41 (ADC2) of IC3 goes from Low to High (around 1V) and BBIC (IC3) detects the insertion ofthe headset.

12 Miscellaneous12.1. How To Replace a Flat Package ICEven if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a sol-dering 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. Anexpert may be able to use a 60 to 80 Watt iron where some-one with less experience could overheat and damage thePCB foil.
• FluxRecommended Flux: Specific Gravity → 0.82.Type → RMA (lower residue, non-cleaning type)Note: See About Lead Free Solder (PbF: Pb free) (P.4).
12.1.2. Removal Procedure1. 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 givepressure to the P.C. board when cutting the pins witha cutter.
2. Make a few cuts into the joint (between the IC and itspins) first and then cut off the pins thoroughly.
3. While the solder melts, remove it together with the ICpins.
When you attach a new IC to the board, remove all solderleft on the land with some tools like a soldering wire. If somesolder is left at the joint on the board, the new IC will not beattached properly.
12.1.3. Procedure1. Tack the flat pack IC to the PCB by temporarily soldering
two diagonally opposite pins in the correct positions onthe PCB.
Be certain each pin is located over the correct pad on the PCB.
2. Apply flux to all of the pins on the IC.
3. Being careful to not unsolder the tack points, slide the sol-dering iron along the tips of the pins while feeding enoughsolder to the tip so that it flows under the pins as they areheated.
12.1.4. Removing Solder From BetweenPins
1. Add a small amount of solder to the bridged pins.2. With a hot iron, use a sweeping motion along the flat part
of the pin to draw the solder from between the adjacentpads.
