Charging - Sony BC-1WD Operating Instructions Manual

Charging

Precautions
• Use the BC-1WD/1WDCE in surroundings with
temperatures at 0°C to 40°C (32°F to 104°F).
Charging at low temperatures is difficult, so it is
recommended that the battery packs be charged at
between 20°C to 30°C (68°F to 86°F).
• Avoid using or storing the BC-1WD/1WDCE in
places susceptible to dust or corrosive gases.
• Avoid using or storing the BC-1WD/1WDCE in
places subject to direct sunlight.
• Do not cover the ventilation holes.

Charging
Turn the POWER switch ON. First the battery packs
are discharged and then charged in order from 1 to 4.
The BC-1WD/1WDCE automatically conducts
refreshing (discharge) before charging to prevent
against battery pack memory effects. When you have
no time to refresh the battery packs, press the
REFRESH OFF button and it will light.
Consequently, charging will start without refresh
discharging first.
