1. Power ON
'Power ON' Does not work
Check the current consumption
Current consumption
≥100mA ?
Check the V bat. voltage
Down load again
Voltage ≥ 3.3V ?
Check the pin of U100
pin #11 ≥ 2.8V ?
Pin #9=1.8V?
Check the Initial operation
END
pin #39 and #33 = 2.8V
Charge the Battery
Check the clock generation
circuit (OSC400, U405 pin#4)
Check the clock signal
at pin #3 of OSC400
Freq.=13MHz,Vrms 300mV
Check U100 and C113
Check U100 and C114

2. System Initial
The pin #9 of U100 = 1.8V
and pin #11 of U100=2.8V?
Initial Failure
Is the pin #19 of U100
" Low --> High" ?
There is 32.768KHz wave
form at the C327, C328 ?
Is the pin #25 of U100
is High ?
The voltage is "High"
at the C107,C109,C110 ?
LCD Display OK ?
Sound operation OK ?
