3-2-2 HDD Drop Detection Function (HDD Protection)

The "HDD Protection" function withdraws the HDD head from the disk (stops recording/playback)
if the DVD video camera/recorder goes into a weightless condition: The default setting is "On".
This DVD video camera/recorder will detect weightless condition not only when you are in the air
during skydiving, bungee jumping, etc., but also when you jump up and down with the DVD video
camera/recorder in hand, or swing your hand holding it at a speed equivalent to its drop speed.
There may be momentary HDD head withdrawal time when jumping up/down or hand swing-
down, but recording or playback will hardly be affected because of the data that the buffer circuit
temporarily saves.
If weightless condition, such as skydiving, lasts a long time, the data temporarily stored in the
buffer circuit cannot compensate for recording or playback, so normal recording/playback will not be
possible.
Specify "HDD Protection: Off" from the record functions setup menu if you plan to record in a
weightless condition for an extended time.
The "HDD Protection: Off" setting will automatically return to "On" when the DVD video camera/
recorder is powered next time.

3-2-3 Dubbing Button

Used to dub the movies/sounds recorded on the HDD to a DVD by the following procedure:
•Set the power switch to "OFF" or "DVD", press the DISC EJECT button, and then load a
recordable DVD (DVD-RAM, DVD-RW, DVD-R, +RW).
If the power switch is set to "HDD" or "SD", the DISC EJECT button will not work, but if disc
replacement is necessary during dubbing, the DISC EJECT button will work even if the power
switch is set to "HDD".
•Set the power switch to "HDD", and then press the DISC NAVIGATION button.
•Press the DUBBING button: All scenes recorded on HDD will be dubbed. To select the scenes
you wish to dub, press the MENU button instead of the DUBBING Button: From the displayed
scene menu, choose "Dubbing", and execute "Select Scenes".
The following shows reference for the dubbing speeds. The dubbing speed will vary depending on
the movie recording mode. Also, the dubbing speed will decrease when the number of scenes to be
dubbed is higher and the temperature inside the DVD video camera recorder is higher:
•XTRA: Approx. normal
•FINE: Approx. 1.5 times the normal
•STD: Approx. 3 times the normal
