PRECAUTIONS
Hard Disk Drive
The distance between the head and disk that read and
write data on the hard disk drive (hereinafter known as
the HDD) is a miniscule 0.02µm. Vibrations and
physical shocks to the HDD may therefore result in the
head coming into contact with the disk, producing
dents and scratches to its surface. This will
consequently prevent data from being read, and will
result in disk crashes if use is continued. It is therefore
necessary to handle the recorder with great care.
„ Installation and Changing the Location of
Installation
• Do not move the recorder or commence the
installation process when the power is turned on
or immediately after the power has been
switched off (for approximately one minute)
under any circumstances. (The HDD will
continue to rotate due to inertia for a few
moments after the power has been switched off,
and vibrations or physical shocks will result in
damage.)
• Wrap the recorder in protecting packing to
prevent physical shocks.
„ Handling
• Handle this equipment with care. Do not subject
it to physical shock.
• Do not unplug the power cord during recording
or playback, or when the HDD is being
accessed.
• The hard-disk is a consumable item.
Replacement is recommended after 10000
hours of use (if use in a 25°C environment). For
information on maintenance planning and costs,
consult your nearest JVC dealer.
„ It is recommended that an UPS (Uninterruptible
Power Supply) is used when installing
additional external hard disk drives to make
sure the system remains stable. (Page 64)
„ If a power failure occurs during formatting of
hard disk, disconnection, or when configuring
or disabling mirroring, operation of the
equipment may be disabled even if it is
connected to the UPS.
„ Please note that we will not provide
compensation for any failure during recording
or playback due to defects in this equipment or
the hard disk drive.
„ Please note that recorded images will be erased
when replacing hard disks. Note that there are
cases where recorded images may be erased
when software is upgraded.
