  • Page 2: About Lead Free Solder (Pbf: Pb Free)

    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).

  • Page 3: Suggested Pbf Solder

    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.

  • Page 4: For Service Technicians

    1.2.2. Handset (Component View) Note: The location of the “PbF“ mark is subject to change without notice. 2. 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. 2.

    The voltage from the AC is supplied to the main charge circuits. Normal charge (290 mA) of maximum 6-hours is started soon after the Handset is placed on the base unit. Then it changes to trickle charge (15 mA on the average) to prevent from overcharging. Normal charge : Q150 is ON Trickle charge : Q150 is OFF 16.4.

Telephone Line Interface Telephone Line Interface Circuit: Function - Bell signal detection - ON/OFF hook and pulse dial circuit - Side tone circuit - Auto-disconnect circuit/Parallel connection detection circuit Bell signal detection and OFF HOOK circuit: In the idle mode, Q4 is open to cut the DC loop current and decrease the ring load.

  • Page 49: Auto Disconnect Circuit

    Side Tone Circuit: Basically this circuit prevents the TX signal from feeding back to RX signal. As for this unit, TX signal feed back from Q1 is canceled by the echo canceller of DSP. Note: DSP is IC201. CPU DATA (BASE UNIT) 16.7.

  • Page 52: Charge Circuit

    Circuit Operation: When the Battery is inserted into the unit, Power Down signal and Reset signal are generated by IC205, IC203, Q212 and Q205 as shown below. The Reset signal will be generated when Charge-ON. 18.4. Charge Circuit Ni-MH battery is connected to (BATT+, BATT-). When the handset is put on the cradle of the base unit, the power is supplied from CHARGE1 and CHARGE2 terminals to charge the battery.

  • Page 53: Sending Signal

    18.6. Sending Signal The voice signal from the microphone input to DSP (46-47). CN203 is the headphone jack. When the headphone is connected, the Q206 detect it. The input from the microphone of the handset (MIN, MIP) is cut and the microphone signal from the headphone is input to DSP (36). Also the power for the microphone is supplied from Q211, and the power is turned OFF on standby.
