4.14. Circuit Operation (Charger Unit)
The voltage from the AC adaptor is supplied to the charge circuits. Main charge (180~250 mA at the Battery) of maximum 7-
hours is started soon after the handset is placed on the charger unit. Then it changes to Trickle charge to prevent from over-
charging.
Charging form
The route for this is as follows: DC+pin of J1(+) → F1 → D1 → R1 → CHARGE+pad → Handset → CHARGE-pad → DC-pin of
J1(-).
