Precautions for Handling Hard Disk
Drive
This unit comes with a high-precision hard disk device. Be
careful not to exert vibration or impact on this unit when
handling it. Exertion of vibration or impact particularly
when the power is on or when the hard disk is being
accessed may cause this unit to break down.
The distance between the head and the disk is only about
μ
0.02
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,
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.
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.
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 25
reference time and not a guarantee for HDD life span.)
For inquiries on maintenance plans and expenses,
consult your nearest JVC KENWOOD dealer.
When installing an external hard disk, we recommend the
use of UPS (uninterruptible power supply) to ensure the
stable operation of the system.
Power failure that occurs during formatting or
disconnection of the HDD may affect its subsequent use
even when the UPS is connected.
JVC KENWOOD 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.
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.

protect the system until the supply voltage stabilizes
again.
Eliminate static electricity before performing work that
requires you to touch the input/output terminals, such as
when installing devices.
Do not touch the rear panel of this unit when it is running
as static electricity may cause it to malfunction.
When there is a large amount of data recorded on this
unit, such as short alarm records, a longer time may be
required during search or backup. This is not a
malfunction.

The width of the border lines (black in color) of images on
the split screen varies according to the type of input
signals. This is due to the characteristics of the camera's
input signals, and is not a malfunction. The condition may
also be improved by adjusting this unit. For details, consult
our authorized dealers or JVC KENWOOD service
