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 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 although, with some precautions, standard Pb solder can also be used. 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). In case of using high temperature soldering iron, please be careful not to heat too long. · PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C). · If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and be sure that any remaining is melted prior to applying the Pb solder. · 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).
1.1.
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 manufac turer'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.

20.3. Telephone Line Interface
· Bell signal detection · Clip signal detection · ON/OFF hook circuit · Audio circuits Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection: In the standby mode, Q2 is open to cut the DC loop current and decrease the ring load. When ring voltage appears at the TP3 (A) and TP40 (B) leads (when the telephone rings), the signal is transferred as follows; · A C4 R2 R29 IC2 (DLP) [BELL & CLIP] · B C3 R1 R30 IC2 (DLN) [BELL & CLIP] ON/OFF hook circuit: In the standby mode, Q2 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 IC2 detects a ring signal or press the TALK Key onto the handset, Q3 turns on and then Q2 turns on, thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow is for the loop current. · A R77 D2 Q2 R8 Q3 D2 B [OFF HOOK]
20.4. Transmitter/Receiver
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 Pass: *Refer to SIGNAL ROUTE (P.64).
20.4.1. Transmitter Block
The voice signal input from the TEL LINE interface goes to RF Module (IC3) through DECT BBIC (IC2) as shown in BLOCK DIAGRAM (BASE UNIT) (P.57) The voice signal passes through the analog part of IC2 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 IC3, 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.
20.4.2. Receiver Block
The signal of 19.2 MHz band (18.81792 MHz ~ 18.97344 MHz) which is input from antenna is input to IC3 as shown in BLOCK DIAGRAM (BASE UNIT) (P.57). In IC3, the signal of 19.2 MHz band is downconverted to 864 kHz signal and demoduleted, and goes to IC2 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.
20.5. Pulse Dialing
During pulse dialing the hookswitch (Q2,Q3) 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 dialpulses, the PULSE_DIAL signal turns on Q7.
