When the Power lamp is flashing during charging
Flashing with approx. 0.5 second period (off for approx. 0.25 second, on for approx. 0.25 second):
≥ Check that the USB terminals of this unit or the connecting device, such as PC are not dirty or
covered with a foreign object, and reconnect correctly. If a foreign object or dirt is present, turn off
this unit before removing.
≥ The environment is at an extremely high or low temperature. Wait until the temperature has
returned to an appropriate level and try charging again. If you are still unable to charge, there may
be a fault in this unit or the connecting device.
Flashing with approx. 4 second period (off for approx. 2 seconds, on for approx. 2 seconds):
≥ When the battery is over discharged or the temperature of the battery is too high or low. It can be
charged, but it may take a few hours to complete the charging normally.
≥ It will flash in approx. 2 second intervals when normal charging resumes. Even in such cases, it
may start flashing in approx. 4 second intervals until charging is completed depending on the
conditions of use.
Off:
≥ Charging has finished.
About the Extended Battery (optional)
You can perform recording over a long period of time with an Extended Battery/VW-BTA1 (optional).
Approximate recordable times are listed below.
≥ To estimate the total recordable times, add the times below to the corresponding recordable times
for the built-in battery of this unit

≥ "h" is an abbreviation for hour, "min" for minute and "s" for second.
≥ These times are approximations.
≥ The capacity of the Extended Battery VW-BTA1 indicates the storage capacity of its built-in
battery, and not the actual quantity of electricity that can be supplied.
≥ Recordable times vary depending on the conditions of use, including how high or low the
temperature is.
≥ When an Extended Battery is used, it works as a power source and charges the built-in battery at
the same time.
≥ For information on the use of an Extended Battery, including how to attach and charge it, refer to
the operating instructions for it.
