¡ Do not recharge any battery pack other than Battery Pack BP-511A, BP-
514, BP-511, or BP-512.
¡ If the battery is left in the camera for a prolonged period without the
camera being used, a low electrical current may be discharged
excessively and the battery’s service life may be affected. When not
using the camera, remove the battery and attach the protective cover to
prevent shorting. Before using the camera again, be sure to recharge the
battery.
¡ After the red lamp lights, continue to recharge
the battery for an hour to attain a full charge.
¡ By referring to the marking, you can attach the
protective cover to the battery to indicate whether
the battery has been recharged or not.
¡ After recharging the battery, detach it and unplug the power cord from
the power outlet.
¡ The time required to recharge the battery depends on the ambient
temperature and battery’s recharge level.
¡ The battery pack can operate in temperatures from 0°C to 40°C (32°F to
104°F). However, for full operating performance, using it between 10°C
(50°F) and 30°C (86°F) is recommended. In cold locations such as ski
areas, battery performance temporarily decreases and the operating
time may be shorter.
¡ If operating time is sharply reduced even after normal recharging, the
battery pack may have reached its service life. Replace it with a new
battery.
