IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING
If lead free solder was used in the manufacture of this product the printed circuit boards will be
marked PbF.
Standard leaded, (Pb), solder can be used as usual on boards without the PbF mark.
When this mark does appear please read and follow the special instructions described in this
manual on the use of PbF and how it might be permissible to use Pb solder during service and
repair work.

  • Page 2: Suggested Pbf Solder

    standard solder or solder that contains 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.

  • Page 3: For Service Technicians

    “PbF” is marked on the PCB to show that Pb free solder is used. (See the figure below.) 1.2. NOTE Current models of the KX-TDA0142CE use PbF. Early-production models do not. 2. FOR SERVICE TECHNICIANS ICs and LSIs are vulnerable to static electricity.

    12. HARDWARE DESCRIPTION 12.1. FUNCTION DESCRIPTION KX-TDA0142CE is the Cell Station (CS) for TDA series. CS converts voice data from PBX to radio signal and transmits to Portable Station (PS). Conversely CS converts radio signal from PS to voice data and transmits to PBX.
  • Page 26 signal and 4MHz clock) and digital data in ST-BUS format from the analog signal provided by PBX. These clocks and digital data is transferred to FPGA (IC101) and HDLC control IC (IC112). HDLC means High Level Data Line Control, a protocol for highly reliable data communication. This ST-BUS digital data contains data channel, control channel and voice channel.
  • Page 27 Extracts voice data from ST-BUS digital data and changes format to IOM-2 format, then provides to BBIC. (2) Superframe detection, delay compensation Detects super frame synchronization signal from HK bit in the ST-BUS digital data and compensates time difference of delay caused by the different cable length from CSIF card, then provides to PSYNC pin of BBIC.
