a temperature of 25°C (77°F). Charging may take longer depending on the conditions of
use and the environment.
To check the remaining battery charge, detach the micro USB cable and check the
(remaining charge indicator) on the screen.
Note
If the charge lamp flashes when the battery pack is not fully charged, remove the battery
pack from the camera and then re-insert it to recharge.
If the charge lamp on the camera flashes when the AC Adaptor is connected to the wall
outlet (wall socket), this indicates that charging is temporarily stopped because the
temperature is outside the recommended range. When the temperature gets back within
the appropriate range, the charging resumes. We recommend charging the battery pack
at an ambient temperature of between 10°C to 30°C (50ºF to 86ºF).
Connect the AC Adaptor to the nearest wall outlet (wall socket). If malfunctions occur
while using the AC Adaptor, immediately disconnect the plug from the wall outlet (wall
socket) to disconnect from the power source.
When you use a completely new battery pack or a battery pack that has not been used for
a long time, the charge lamp may flash quickly when the battery is charged for the first
time. If that happens, remove the battery pack from the camera and then re-insert it to
recharge.
Do not continuously or repeatedly charge the battery pack without using it if it is already
fully charged or close to fully charged. Doing so may cause a deterioration in battery
performance.
When charging is finished, disconnect the AC Adaptor from the wall outlet (wall socket).
Be sure to use only genuine Sony brand battery packs, micro USB cables (supplied) and
AC Adaptors (supplied).
