1 Safety Precaution
1.1. For Service Technicians
ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover the plastic parts boxes with aluminum foil and ground them. 2. Ground the soldering irons. 3. Use a conductive mat on the worktable. 4. Do not touch 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).

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.

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; · A C4 R6 R33 IC7 Pin 60 (CID INp) · B C3 R4 R35 IC7 Pin 52 (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. · A D3 Q3 Q5 R21 R22 D3 B [OFF HOOK]

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.13).
4.2.4.1.
Transmitter Block
The voice signal input from the TEL LINE interface goes to RF Module (IC10) 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 IC10, the carrier frequency is changing, and frequency modulated RF signal is generated and 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 IC10 as shown in Block Diagram (Base Unit) (P.7). In IC10, the signal of 1900 MHz band is downconverted to 864 kHz signal and demodulated, and goes to IC7 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 Dialing
During pulse dialing 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

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 address of EEPROM (0144) from 00 to 01.

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.
9.4.1.
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)
9.4.2.
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 land 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.
