4-4-2 Updating fi rmware
If you receive information from the factory on tecnical bulletin, etc. that updating fi rmware is
needed, you should update to improve the performance, functions and operability of DVD video
camera/recorder.
Caution
Be sure to acquire the appropriate data before updating the corresponding model, and then create a
disc/card for updating.
If a disc/card for updating a model other than that to be serviced is inserted, an mismatch screen
(Fig. 4-4-2) will appear: Stop updating and remove the disc/card.
1) Acquire the data for updating of fi rmware 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 "Movie" when using a disc for updating, or to "Card Still" when sing a
card for updating.

programs will be automatically updated thereafter. During updating, screens showing that
designated fi rmware program is being updated will appear, followed by screen showing that
updating is complete.
Not all fi rmware programs need updating every time: If the version of the data on disc/card for
updating is identical to that of fi rmware stored in DVD video camera/recorder, the same version
screen will appear.
6) When all required updating is complete, the screen for verifying the version of updated fi rmware
will appear, and the updated fi rmware will be displayed in red.
Make sure that the fi rmware has been updated to agree with the details specifi ed by the technical
bulletin, etc.
