problem may lie in the digital unit (main board). As there are many potential causes in this case (ASIC, DRAM, etc.), it may be difficult to specify what you should check first. If a mistake is made in the order of checks, a normal part may be determined faulty, wasting both time and money.
Page 89
What are the main signals for booting up the unit? Please refer to DIGITAL BLOCK DIAGRAM The ASIC (IC501) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored in the ROM (IC502), then follows the instructions for controlling each IC.
Page 90
As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 5V (H) and 0V (L). The following shows NG and normal wave patterns. NG Wave pattern (Refer to NG EXAMPLE) Normal Wave Patterns...
Page 91
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.

2.3.8. ANALOG BOARD SECTION This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line. The signal mainly flowing on this route is analog.

CROSS REFERENCE: CHECK SHEET() 2.3.9. DIGITAL SPEAKERPHONE The digital speakerphone has different features from the analog speakerphone. The analog speakerphone switches between Tx or Rx. 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.
Page 104
You cannot check the digital speaker phone by the signal route test mentioned in the Analog Board Section because the level is always changing as stated above. Therefore, there is a service function for this troubleshooting. In this service mode, you can set the mute to either Tx or Rx.

This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding voltage test, intentional short circuit test, etc.
Page 109
2.3.10.3. BROKEN PARTS REPAIR DETAILS (D101, D102, D103, D104) Check for a short-circuit in terminal 4. If D101, D102, D103 and D104 are short-circuits, F101 will melt (open). In this case, replace all of the parts (D101, D102, D103, D104, F101).

6.4.4. SCANNING BLOCK The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, an LED array, and photoelectric conversion elements.

The stepping motor works for both transmission and reception. 2. Motor During motor driving, pin 163 of ASIC IC501 becomes a high level, and Q503, Q501 turns ON. As a result, +24V is supplied to the motor coil. Stepping pulses are output from ASIC IC501 pins, 157, 160~162, causing driver IC508 pins, 16~13 to drive the Motor Coil.
Page 189
When the motor suspends while it is in the receive mode (about 70~80 msec), pin 163 of ASIC IC501 becomes a low level and Q503 turns OFF. Then Q501 also turns OFF, and instead of +24 V, +5 V is supplied through D501 so that the motor is held in place. When the system is in the stand- by mode, all of the motor drive transistors turn OFF.
