Sony Cyber-shot DSC-RX100 IV - Manual (Page 33)

Note
If the charge lamp flashes when the battery pack is not fully charged, remove the battery
pack or disconnect the USB cable 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 this happens, remove the battery pack or disconnect the USB cable 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).
