Information:
1) The version number of loader firmware cannot be
confirmed on the information display/version screen
because of design limitations.
2) With actual screens, figures and letters will appear in
digits displayed as x on illustrations.
3) The number at the bottom right of screens shows the
operation hours of disc drive unit: Use this for reference
to determine how long the customer has used the DVD
video camera/recorder.
Example: 10355: 103 hours 55 minutes
This number will not appear, however, when the power
switch is set to "CARD PHOTO". When the disc drive
unit is replaced, the operation hours of the newly
assembled unit will appear.

4-5-2 Updating firmware

If you receive information from the factory on service bulletin, etc. that updating firmware is
needed, you should update to improve the performance, functions and operability of DVD video
camera/recorder.
1) Acquire the data for updating of firmware and create a disc or card for updating: Information on
how to do this will be reported on service bulletin, etc.
2) Set the power switch to "OFF", and then use the AC adapter/charger to power the DVD video
camera/recorder: A battery cannot be used to do this because it may interrupt power of DVD
video camera/recorder during updating.
3) Insert the disc/card for updating.
4) Set the power switch to "VIDEO" when using a disc for updating, or to "CARD PHOTO" when
sing a card for updating.
