The power is supplied to the DECT BBIC, RF Module, EEPROM and Charge Contact from AC Adaptor (+6.5V) as shown in
Fig.101. The power supply is as follows;
• DECT BBIC (IC7):
CN2 (+6.5V) → IC1 → Q9 → IC7
CN2 (+6.5V) → IC1 → Q8 → IC7
• RF Module (IC10):
CN2 (+6.5V) → IC1 → Q9 → IC10 (PLL)
CN2 (+6.5V) → IC1 → Q10 → IC10 (Power AMP)
• EEPROM (IC5):
CN2 (+6.5V) → IC1 → Q9 → IC5
• FLASH MEMORY (IC9):
CN2 (+6.5V) → IC1 → IC9
• TAM Companion (IC8):
CN2 (+6.5V) → IC1 → Q9 → IC8
CN2 (+6.5V) → IC1 → Q8 → IC8
• Charge Contact (TP16):
CN2 (+6.5V) → R55, R56 → TP16
