Recording and playback
precautions
Recording operation in high-
vibration environments
• If the unit is exposed to a constant
vibration during operation, recording or
playback may be stopped to protect the
HDD. In such cases, integrity of the data
during vibration is not guaranteed.
• If recording is stopped due to vibration,
you may need to restore the HDD to start
recording again after removing the
source of vibration. However, the data
recorded immediately before the forced
stop may be lost even after HDD
restoration. The duration of data that
cannot be restored differs depending on
the camcorder model and recording
mode.
For more information on restoring the HDD,
refer to the section on memory card restoration in
the operating instructions of your camcorder.
Recording operation and data
integrity when battery power is low
or power is cut off
• When the remaining battery capacity is
low, the BATTERY indicator flashes. If
you continue to use the unit, the unit
automatically stops recording for safety
and eventually powers itself off.
For more information on the BATTERY indicator
flashing, see "Status Indications" (page 22).
• If the battery pack or battery charger is
disconnected during recording, integrity
of the data recorded is not guaranteed. All
of the data stored on the HDD may be
damaged.
• If the PHU connection cable is
disconnected during recording, recording
will stop. The data recorded up to that
point is stored, but integrity of such data
is not guaranteed.
• If the power is accidentally turned off
during recording, recording will stop.
However, the data recorded up to that
point is stored normally.
• The unit may stop operating if it detects
that the ambient temperature is lower or
higher than the HDD guaranteed
operation temperature range. This is done
to protect the unit. If this occurs, wait
until the ambient temperature returns to
the guaranteed operation temperature
range before trying to use the unit. See
"Specifications" (page 20) for the
guaranteed operation temperature range.
• If the unit stops responding during power
off (including automatic power off
because of low battery power), power the
unit off by pressing the power switch and
holding it for at least three seconds.
However, recorded data is not guaranteed
in this case.
Forcibly cutting power by disconnecting
the battery pack or battery charger may
damage the unit.
About the drop detection function
This unit is equipped with a 3G sensor to
protect the internal HDD when the unit is
dropped or overturned. The sensor detects
differences in acceleration and may activate
the drive protection function if you jump
down from a high place, run down a flight
of stairs, or otherwise cause the unit to
detect acceleration similar to that of the unit
being dropped. In such cases, the integrity
of the recorded data is not guaranteed. In
addition, the drive protection function may
not activate if a drop is combined with
vibration and flipping of the unit.
