Notes:
• Charge the battery pack between 50°F and 86°F
(10°C and 30°C). The battery pack may not charge
properly at temperatures too low or too high.
• The battery pack and charger become warm
during charging. This is not a malfunction.
• Using the zoom (see page 19) and other
functions or turning the power on and off
frequently will increase power consumption. This
may result in a decrease of more than 50% in the
actual recording time compared to the maximum
continuous recording time listed above.
• The charging time and recording time may vary
depending on the ambient temperature and the
condition of the battery pack.
• See page 66 for more information on using the
battery pack.
Caution:
• Charge only SHARP model BT-L221 or BT-L441
battery packs. Other types of battery packs may
burst, causing personal injury and damage.
Extending battery pack life
Even when the battery pack is not used, the
capacity of the battery pack will naturally
deteriorate over time. To limit the deterioration
of the capacity, it is recommended to perform
the following procedure at least once every six
months:
1 Charge the battery pack until the CHARGE
indicator of the charger turns off.
2 Attach the battery pack to the camcorder,
and set the Power switch to CAMERA
without inserting a cassette. Allow the
battery power to fully discharge by leaving it
on the camcorder until the camcorder
power automatically turns off.
3 Remove the battery pack and store it
between 50°F and 68°F (10°C and 20°C).
