The power is supplied to the DECT BBIC, QSPI FLASH MEMORY, EEPROM and Charge Contact from AC Adaptor (+5.5 V) as
shown in Fig.101. The power supply is as follows;
• DECT BBIC (IC7):
DC Jack (+5.5 V) → IC2 → IC7
DC Jack (+5.5 V) → IC2 → Q9 → IC7
DC Jack (+5.5 V) → IC2 → Q8 → IC7
• EEPROM (IC401):
DC Jack (+5.5 V) → IC2 → IC7→ IC401
• Charge Contact (TP16):
DC Jack (+5.5 V) → R56 → R55 → D22→ TP16
• QSPI FLASH MEMORY:
DC Jack (+5.5 V) → IC2 → IC7 → IC431
