THE UNIT CAN COPY, BUT CANNOT EITHER TRANSMIT/RECEIVE LONG DISTANCE OR INTERNATIONL COMMUNICATIONS The following two causes can be considered for this symptom.
  • Page 52 KX-FP85 (Cause and Countermeasure) As shown in the chart above, the total handshaking time must be reduced, but because of the long distance connection and linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be tried.
  • Page 53 KX-FP85 (Cause C) This model is FAX1 and the other party is FAX2. For transmission from this model to FAX2, FAX2 executes automatic reception and transmits a CED signal (2100 Hz) followed by a DIS signal. As the echo cancelers stops as described in cause B, the echo of the DIS signal returns to FAX2. On the other hand, this model detects the DIS signal and transmits a DCS signal.

  • Page 66: Digital Board Section

    KX-FP85 2.3.6. DIGITAL BOARD SECTION When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem. The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.) The first step is to check the power source.
  • Page 67 KX-FP85 2.3.6.1. DIGITAL BLOCK DIAGRAM You also need to check the signal lines listed here [List 1] when the unit fails to boot up the system. Those signal lines should remain normal. Other signal lines are not directly related to that failure even if they have faults or troubles.
  • Page 68 KX-FP85 NG Wave pattern (Refer to NG EXAMPLE)
  • Page 69 KX-FP85 Normal Wave Patterns Remarks: When you use an oscilloscope to judge whether a signal to be tested is normal or NG, perform the signal check in exactly the same order as in [List 1]. (If the ASIC fails to access the ROM, the ASIC cannot access SRAM or DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals.
  • Page 70 KX-FP85 I/O and Pin No. Diagram...
  • Page 71 KX-FP85 After the power is turned on, the ASIC initializes and checks each IC. The ROM, SRAM, and modem are checked. If initialization fails for the ICs , the system will not boot up. In this case, please find the cause as follows.

  • Page 73 KX-FP85 2.3.6.2. FLASH MEMORY (IC501) If the unit is working correctly but the VOICE GUIDANCE (voice prompt) is not audible, you should check the Flash Memory. A voice message is pre-recorded in the Flash Memory (IC512). So, when you find an IC512 malfunction and replace it with a new one.

For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line.
  • Page 77 KX-FP85 2.3.7.2. DEFECTIVE ITS (Integrated Telephone System) SECTION 1. No handset and speakerphone transmission / reception Perform a signal test in the ITS or the NCU section and locate a defective point (where the signal disappears) on each route between the handset microphone and telephone line (sending), or between the telephone line and the handset speaker (receiving), or between the microphone and the telephone line (sending), or between the telephone line and the speaker (receiving).

Either Tx or Rx is able to pass through a telephone line or speaker, depending on the Tx and Rx signal (voice) level. The higher-level signal (either TX or RX) can pass through the route.
