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 Warning 2.1. Battery Caution 1. 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. 2.2. 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 Component pin solder (Slice View) 4 Component KX-TG5521RUB/KX-TGA551RUB 2.2.1. 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: 0.3 mm, 0.6 mm and 1.0 mm. 0.3 mm X 100 g 2.3. 0.6 mm X 100 g 1.0 mm X 100 g Discarding of P.C.

Telephone Line Interface <Function> • Bell signal detection • Clip signal detection • ON/OFF hook circuit Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection: In the standby mode, Q3 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 → L2 → C4 → R6 → R33 → IC7 Pin 21 (CID INp) • A → L1 → C3 → R4 → R35 → IC7 Pin 20 (CID INn) ON/OFF hook circuit: In the standby mode, Q3 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 IC7 detects a ring signal or press the TALK Key onto the handset, Q4 turns on and then Q3 turns on, thus providing an off-hook condition (DC current flows through the circuit) and the following signal flow makes the loop current. • B → L2 →D3 → Q3 → Q5 → R21 → R22 → D3 → L1 →A [OFF HOOK] 4.2.4. 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.14). 4.2.4.1. Transmitter Block The voice signal input from the TEL LINE interface goes to RF Power Amp. (IC801) through DECT BBIC (IC7) as shown in Block Diagram (Base Unit) (P.7) The voice signal passes through the analog part of IC7 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 IC7, the carrier frequency is changing, and frequency modulated RF signal is generated.In IC801,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. 4.2.4.2. Receiver Block The signal of 1900 MHz band (1881.792 MHz ~ 1897.344 MHz) which is input from antenna is input to IC7 as shown in Block Diagram (Base Unit) (P.7). In IC7, 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. 4.2.5. Pulse Dialling During pulse dialling the hookswitch (Q3, Q4) is used to generate the pulses using the HOOK control signal, which is set high during pulses. To force the line impedance low during the “pause” intervals between dial pulses, the PULSE_DIAL signal turns on Q2. 10 Q4, Q9, R7 11 R45 BELL LED KEY LED LCD-BACK LIGHT LCD BATTERY TERMINAL BATT- BATT+ CHARGE(-) D7 CHARGE(+) CHARGE CHARGE CIRCUIT CONTACTS MIC RECEIVER SPEAKER 32 36 54 55 SCL 68 52 63 SDA 66 1.8 V 13 1.8 V Q2 56 VBAT SDA 58 RESET CSB CD IC3 EEPROM SCL 57 CHARGE_CTRL 31 CHARGE 20 16 19 35 15 LDO_CTRL CPU Analog Front End A/D D/A DSP IC1 BBIC ADPCM Codec Filter Speech Decoding Speech Encoding 42 TXn TXp RXp RXn COLUMNS DA801 KEYPAD ANT1 ANT1 BATTERY IC801 8 9 RF PA 10.368 MHz 6 7 3 4 ON SWITCH ROWS 44 10 9 XTAL X1 VDD-PADRY Pon 73 PSEL 74 TXon 80 78 77 75 2 3 RXon KX-TGA551 BLOCK DIAGRAM (HANDSET) CP3.0V CP4.0V 43 Charge Pump 22, 23, 24, 25, 26 48, 49, 50, 51 BMC RF PLL MOD/DEMOD Burst Decoding Burst Encoding 5 4.3. 33 KX-TG5521RUB/KX-TGA551RUB Block Diagram (Handset) KX-TG5521RUB/KX-TGA551RUB 4.4. 4.4.1.

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.4) 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. 60 KX-TG5521RUB/KX-TGA551RUB 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. 61 KX-TG5521RUB/KX-TGA551RUB 12.2. How to Replace the Shield Case 12.2.1.
