  • Page 2: For Service Technicians

    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. 2. Ground the soldering irons.

  • Page 3: Installing The Batteries

    3. Use a conductive mat on the worktable. 4. Do not touch IC or LSI pins with bare fingers. 2. CAUTION Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommendenced by the manufacturer. Dispose of used batteries according to the manufacture’s Instructions.

  • Page 7 6.1.2. Connecting Telephone Line Cords A maximum of eight KX-TS3282Bs can be connected in parallel. You can also connect KX- T3281W. To use the intercom, you must connect the telephone line cord to the LINE1/2 telephone jack of the unit.
  • Page 8 - If another model telephone is connected to the KX-TS3282B except for KX-TS3281W, the line indicators of this unit will not function for that telephone. - If you re-connect the telephone line cord(s), confirm that all of the extension indicators light with the AC adaptor connected, then connect the telephone line cord(s).
  • Page 10 - If you do not connect other extensions, you do not need to use a T- adaptor. Connect a 2-wire telephone line cord to the LINE1/2 telephone jack of the unit directly. 6.1.3. Connecting a Communication Device After connecting the telephone line cord to a two-line telephone jack, you can connect a communication device (computer, modem, fax, answering machine, etc.) through this unit using the LINE2/DATA jack.
  • Page 11 - If the communication device is in use, use LINE 1 to make or answer other calls. Otherwise the communication device may not operate properly. 6.2. Dialing Mode If you have touch tone service, set to Tone. If rotary or pulse service is used, set to Pulse. Your phone comes from the factory set to Tone.

Telephone Line Interface Circuit Operation: ( )...Line 2 This unit is connected to the telephone circuit by a 6-core full modular jack. When L1 (L2) key is pressed, the speakerphone goes ON automatically, obtaining Line 1 (Line 2).

  • Page 44: Reset Circuit

    becomes Low according to selected L1 (or L2), and Q130, Q131 (Q230, Q231) turned on and the Line Switch for that line (Line 1, Line 2) closes. Line current flows through Q130. As a result, a loop is formed through D101 (D201) Emitter of Q130 (Q230) Collector of Q130 (Q230)

  • Page 45: Pulse Dial Circuit

    Function: The tone dialing circuit consists of a DTMF (Dual Tone Multi Frequency) signal generator (outputted from) for tone dialing, and also a circuit for outputting the signal to line. The DTMF circuit indentifies inputs from the 12 keys (1, 2, 3, 4, 5, 6, 7, 8, 9, 0, ) by means of a total of seven frequencies, that is four low frequencies (Low group) and three high frequencies (High group).
  • Page 46 Attenuator, Comparator and Attenuator Control. The circuit analyzes whether the TX(transmit) or the RX(receive) signal is louder, and then it processed the signals such that the louder signal is given precedence. The Voice Detector provides a DC input to the Attenuator Control corresponding to the TX signal. The Comparator receives a TX and a RX signal, and supplies a DC input to the Attenuator Control corresponding to the RX signal.
  • Page 47 (Holding) If the Hold key is pressed during a conversation using the handset or the speakerphone, the CPU IC801 judges that a hold status has been applied, consequently pin 67 (pin 65) of IC801 becomes High level, and PC4 (PC3) goes ON. Q132 and Q133 (Q232 and Q233) goes ON, and Q134 (Q234) goes ON, and the line voltage is held.
  • Page 48 12.8.2. Data Communication Block 1. Data Transmission The oscillated waveform of 455 kHz (A) at pin 10 of IC701 becomes the tone burst signal (C) at pin 12 of IC701 by the data signal (B) from pin 31 of the microcomputer IC801. And then it passes the amplifier mixed with the audio FM signal and is transmitted to the telephone line via the transformer (T701).
  • Page 49 *When an intercom transmission is not in use, the waveform of (D) becomes the same burst signal as (C). 2. Data Reception The data that is transmitted to the telephone line from another set is input via T701 in reverse order of the data transmission (D). This burst signal passes BPF701 to separate from the audio signal and then only 455 kHz is extracted (E) at pin 5 of IC701.
  • Page 50 12.8.3. Voice Communication Block 1) Voice Transmission...
  • Page 51 The transmitting signal from the H/S or SP-phone is input to CPI (the expander is used to reduce a noise generated by the transmission system, a cross talk of line transmission, pulse sound, or ring signal, etc.) and then output from CPO after compression according to the signal level. The audio signal compressed by the compander is amplified by Q701 and input to VMI for FM modulation/demodulation and output VTO after the FM modulation.

    Be certain each pin is located over the correct pad on the PCB. 2. Apply flux to all of the pins on the IC. 3. Being careful to not unsolder the tack points, slide the soldering iron along the tips of the pins while feeding enough solder to the tip so that it flows under the pins as they are heated.
