• Turn off the camcorder before connecting or disconnecting the USB power adapter. After you turn off the
camcorder, important data is updated on the SD card. Be sure to wait until the green POWER/CHG indicator
goes out.
• When using the USB power adapter, do not fix it permanently to one place as this may cause a malfunction.
• To prevent equipment breakdowns and excessive heating, do not connect the supplied USB power adapter to
voltage converters for overseas travels or special power sources such as those on aircraft and ships, DC-AC
inverters, etc.
NOTES
• We recommend charging the battery pack in temperatures between 10 °C and 30 °C (50 °F and 86 °F). If
either the ambient temperature or the battery pack's temperature is outside the range of approx. 0 °C to 40 °C
(32 °F to 104 °F), charging will not start.
• The battery pack will be charged only when the camcorder is off.
• If the power supply was disconnected while charging a battery pack, make sure the POWER/CHG indicator
has gone out before restoring the power supply.
• If remaining battery time is an issue, you can power the camcorder using the USB power adapter so the
battery pack will not be consumed.
• While recording, it is recommended to attach a battery pack to the camcorder even when the USB power
adapter is connected. This will prevent the camcorder from turning off in case of a power outage or an
accidental disconnection of the cable.
• Charged battery packs continue to discharge naturally. Therefore, charge them on the day of use, or the day
before, to ensure a full charge.
• We recommend that you prepare battery packs to last 2 to 3 times longer than you think you might need.
• For handling precautions regarding the battery pack, refer to Safety Instructions and Handling Precautions
(A 136). For charging times and approximate usage times, refer to Reference Tables (A 145).
