1 Safety Precautions

1.1. 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.

2Warning

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).

KX-TG2511CA/KX-TG2512CA/KX-TGA250RU

4.2.3. Telephone Line Interface

• 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.

9.3.2. 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.

Setting Method

• Change the handset address of EEPROM (0129) from 00 to 01 by Engineering Mode.

11 Measurements and Adjustments

This chapter explains the measuring equipment, the JIG connection, and the PC setting method necessary for the measurement in Troubleshooting Guide (P.23)

11.1. Equipment Required

• Digital multi-meter (DMM): it must be able to measure voltage and current.

• Oscilloscope.

• Frequency counter: It must be precise enough to measure intervals of 1 Hz (precision; ±4 ppm) Hewlett Packard, 53131A is recommended.

• DECT tester: Rohde & Schwarz, CMD 60 is recommended.

This equipment may be useful in order to precisely adjust like a mass production.

11.2. The Setting Method of JIG (Base Unit)

This section explains the PC setting to use command required in Check Point (Base Unit)(P.35).

• Serial JIG cable: PQZZ1CD300E*

• PC which runs in DOS mode

• Batch file CD-ROM for setting: PNZZTG2511CA

Note:

12 Miscellaneous

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.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.

58

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.

KX-TG2511CA/KX-TG2512CA/KX-TGA250RU

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.

59

KX-TG2511CA/KX-TG2512CA/KX-TGA250RU

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.

60

12.2.4. How to Install the Shield Case

Note:

• If you don’t have special tools (ex. Hot air disordering tool), conduct the following operations.

• Shield case’s No. : PNMC1013Z

1. Put the shield case.

2. Solder the surroundings.
