Please avoid storing or using this unit in the following
places:
• Extremely hot or cold places beyond the allowable
temperature for operation (5°C - 40°C).
• Humid or dry places beyond the allowable humidity
range for operation (30% - 80% RH).
• Dusty or sandy places.
• Places exposed to oil, smoke or steam, such as the
kitchen vicinity.
• Vibrating or unstable places.
• Places prone to condensation.
• Places that generates strong magnetic fields, e.g.,
transformer or motor.
• Places near devices that generate electric waves, e.g.,
transceiver or mobile phone.
• Places that generate radiation, X-rays or corrosive
gases.
Handling the unit
• Please do not place heavy objects on this unit, like a
monitor or TV. Also, do not stack the VR-D0U units on
top of each other.
• Please do not block the ventilation openings.
• Avoid violent shocks to the unit. Do not drop the unit.
Maintaining the unit (Please turn off the power
before performing maintenance work.)
Please wipe the unit with a soft cloth. Do not wipe it with
thinner or benzene lest the surface melts or becomes
dull. For stubborn stains, wipe first with a water-diluted
neutral detergent and then wipe dry.
Please use the supplied power cord. Using a
different type or damaged cord may cause fire
or electric shock.
To save energy, be sure to turn off the system
when not in use.
Do not use the power cord supplied with this
equipment on other devices.
Do not stack up the equipment to prevent
temperature within from rising.
Do not insert foreign object into this unit as this
may cause malfunction or electric shock.
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.
The HDD 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.
If a power failure occurs during formatting of HDD,
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 HDD.
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.
This equipment will automatically reset when minor data
writing errors occur with the HDD or other device in this
equipment’s system.
