FAST very good and clear a great unexpensive job!!! very recomended for all people who are preofessional or hobbists as me!!!!!!

Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.

Very good manual with clear electrical diagrams. Thanks owner-manuals.

Complete original Service Manual in good (scan) quality!
System reset uses the power monitor IC to monitor the +5 V power supply to the main board. If the supply voltage reaches 4.75 V or above, after a time lag of approximately 180 ms due to the time constant of the R.C., the reset signal is changed from L -> H (RSTn). This signal is received by IC136, then input to the CPU (IC101), flash memory (IC102), RTC (IC128), the flash memory card (master) and the flash memory card (slave). To prevent current intake, IC136 uses the CMOS IC. Simultaneously, the reset signal (RST) inverted at IC109 is input to DSP IC120A (Ach), DSP IC120B (Bch), and gate array IC125. KX-TVS50-1 Reset IC Expanded Time Calculation Expanded time (tPLH) = CI � RL � (In (Vcc ÷ (Vcc - (Vs CPU + 0.2)))) + 0.04(ms) CL: F RL: k Voltage: V Vs CPU: CPU reset threshold voltage
