Getting Started
Locations of Storage and Use
ⅷ Do not place this product at the following locations.
Doing so may cause this product to malfunction or break
down.
● Hot or cold places beyond the allowable operating
temperature range (5I to 40I)
● Humid places beyond the allowable operating humidity
range (30%RH to 80%RH) (no condensation)
● Places that emit a strong magnetic field, such as near
transformers and motors
● Places near devices that emit radio waves, such as
transceivers and mobile phones
● Places with considerable dust and sand
● Places with strong vibrations
● Places where water droplets may be formed, such as
window sides
● Places with considerable vapor and oil, such as kitchens
● Places that emit radiation, X-rays, and corrosive gases
ⅷ Using this unit and the cable that is connected to it near
places where strong radio waves or magnetic fields (such
as near radios, TVs, transformers, and monitors) are
emitted may cause noises in the video images or color
changes.
Handling Precautions
ⅷ Do not stack the devices on one another during use.
Heat and noise from the devices may cause the unit to
malfunction or break down, and lead to fire.
ⅷ Do not block the ventilation holes.
Doing so may cause heat to trap inside the unit and result
in fire. Do not use this unit by laying it down sideways,
upside down, or at an angle.
ⅷ Do not place objects on this unit.
Placing heavy objects, such as TV monitors, or objects
that are bigger in size on this unit may cause it to lose
balance and drop or fall, hence resulting in injuries.
ⅷ Do not stand or sit on this unit.
Doing so may cause this unit to fall or break down, and
result in injuries. Keep it out of the reach of young
children.
ⅷ Do not place objects with water (e.g., vases, flower pots,
cups, cosmetic products, and chemicals) on this unit.
Water may enter this unit through the ventilation holes and
result in fire or electric shock.
ⅷ Do not insert objects into this unit.
Metallic or other flammable objects that enter this unit
from the ventilation holes may result in fire or electric
shock.
Precautions for Handling Hard Disk Drive
ⅷ The distance between the head and the disk is only about
0.02
μ m when the hard disk (henceforth HDD) is reading
the data. Vibration or impact that is exerted on the HDD
may therefore cause the head to hit against the disk,
hence causing the disk surface to dent or the disk to chip.
When this occurs, data may not be properly read, or in a
worse scenario, continued use in this condition may result
in head crash (damage). Careful attention must therefore
be paid when handling it.
ⅷ Precautions During Installation and Change of Installation
Location
Moving of this unit or installation work is strictly prohibited
when the power of this unit is on or immediately after the
power is turned off (approximately 1 minute). The HDD
continues to move under its own inertia for some time
after the power is disconnected, and exertion of vibration
or impact during this interval may result in HDD failure.
When moving this unit, wrap it using cushioning materials
to protect it from external shock.
ⅷ Handling Precautions
● Handle this unit carefully without exerting vibration or
impact on it.
● Do not remove the power plug during recording or
playback, or when the HDD is being accessed.
● The HDD is a consumable product. Although it may vary
according to the environment of use, it is recommended to
replace the HDD after using for 18,000 hours in a
surrounding temperature of 25I. (However, this is only a
reference time and not a quaranty for HDD life span. ) For
inquiries on maintenance plans and expenses, consult
your nearest JVC dealers.
ⅷ When installing an external hard disk, we recommend the
use of UPS (uninterruptible power supply) to ensure the
stable operation of the system. [Connecting a UPS]
(A Page 136)
ⅷ Power failure that occurs during formatting or
disconnection of the HDD may affect its subsequent use
even when the UPS is connected.
ⅷ JVC shall not be held responsible for the compensation of
losses incurred in the event that recording or playback
fails due to defects in this unit or its hard disk drive.
ⅷ Images recorded on the HDD will be deleted when you
replace it with a new disk. Note also that recorded images
may be deleted when you upgrade the software for this
unit.
Clock
ⅷ Use of a time server is recommended to ensure recording
at an accurate time.
ⅷ There may be a daily error of 10 to 20 seconds depending
on the operating environment.
ⅷ The clock time may vary significantly when the lithium
battery level used for backup in this unit is running low.
ⅷ Connect the time server to the LAN2 network.
