Circuit Operation (Charge Unit)
To measure the charge-current, R616-619 transfer the current to a voltage.
When the charge-current is 200mA, the voltage is 0.05V.
IC602 amplifies the voltage to 24.5time, then the output voltage is 24.5X0.05=1.225V.
IC601 is DC/DC convertor. This IC adjusts CII to 1.25V.
Then the charge current is adjusted to 204mA.
When charging is completed, the BBIC (IC201) of the portable station set the Q103-Base to "High", then Q102 is turned off. As
a result, the charging current is stopped.

Battery Information
After your Panasonic battery is fully charged [at 25
°C]:
• Operating time may be shortened depending on usage conditions and ambient temperature.
• The battery will drain even while the unit is turned off.
• The PS can receive calls while charging.
• The battery will drain even while the unit is turned off.
• The PS can receive calls while charging.
• Battery consumption increases when the PS is used out of range. If "
" flashes, turn off the PS.
• Clean the handset and the charger contacts with a soft, dry cloth once a month. Clean more often if the unit is subject to
grease, dust or high humidity. Otherwise the battery may not charge properly.
• Read "Important Notice Concerning the Correct Use and Charging of Ni-MH Batteries".
