About the internal hard disk drive
The internal hard disk drive (HDD) is a fragile piece of equipment. Please use the recorder following the guidelines below to protect against possible HDD failure.
We recommend that you back up your important recordings onto DVD discs in order to protect against accidental loss.
•Do not move the recorder while it is on.
•Install and use the recorder on a stable, level sur- face.
•Do not block the rear vent/cooling fan.
•Do not use the recorder in excessively hot or humid places, or in places that may be subject to sudden changes in temperature. Sudden changes in temperature can cause condensation to form inside the recorder. This can be a cause of HDD failure.
•While the recorder is switched on, do not unplug from the wall socket or switch the electricity off from the breaker switch.
•Do not move the recorder immediately after switching it off. If you need to move the recorder, please follow the steps below:
1.After the message POWER OFF is shown in the display, wait at least two minutes.
2.Unplug from the wall socket.
3.Move the recorder.
•If there’s a power failure while the recorder is on there is a chance that some data on the HDD will be lost.
•The HDD is very delicate. If used improperly or in an unsuitable environment, it is possible that the HDD will fail after a few years of use. Signs of problems include playback unexpectedly freezing and noticeable block noise (mosaic) in the picture. However, sometimes there will be no warning signs of HDD failure.
If the HDD fails, no playback of recorded material will be possible. In this case it will be necessary to replace the HDD unit.
xExemption of liability concerning compensation of recorded contents
If the recorder fails to record or play back because
of a fault, Hitachi will not accept any responsibil-
ity for compensation for HDD contents (recorded program data, etc.) or loss of them, or any direct or indirect damage. This also applies if you repair the recorder yourself (including repair of any compo- nents other than HDD).
