as a first-time user and buyer from this site, i found the overall service outstanding!! this product is a godsend as, without it, i would never have been able to find my way around and use my machine as intended. i will certainly use this site again as required. many many thanx!!

This manual is exactly what I needed. This site always has every manual I need, and it is also much less expensive then most other sites. This is the only manual site I will use.

Useful manual, good scan, worth the pay if you find the unit difficult to operate.

Exactly as described, the full user-manual (145 pages). Perfect.
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
