Precautions
• Refer all work related to the installation of this prod-
uct to qualified service personnel or system
installers. 
• Do not operate the unit beyond their its specified
temperature, humidity, or power source ratings. 
Use the unit at temperatures between +5 °C - +45 °C
{41 °F - 113 °F} and where the humidity is between 5 % -
90 %.
The input power source for NTSC model is 120 V AC
60 Hz, for PAL model is 220 V - 240 V AC 50 Hz. 
Performance and lifetime of hard disk drives are easily
affected by heat (used at high temperature) character-
istically. It is recommended to use this unit at tempera-
tures between +20 °C - +30 °C {68 °F - 86 °F}. 
• POWER switch 
The POWER switch is located on the rear of the unit.
Even though the POWER switch is set to OFF, the
power supply will not be cut. To cut the power supply,
unplug the power plug of the unit from the AC outlet.
When using the power supply control unit, turn off the
power of the power supply control unit. 
• Built-in backup battery 
Before the first use, charge the built-in backup battery
(lithium battery) by turning on the power for 48 hours or
more. 
If it is not charged enough, in a case where the power
goes down, the internal clock may keep bad time or the
operative condition may be different to that before the
electric power failure. 
The built-in battery life is approximately 5 years as an
indication of replacement. (This is just an indication of
replacement. We are not providing any guarantee of the
built-in battery lifetime. Replacement cost of the built-in
battery is not covered by the warranty even if it needs
to be done within the warranty period.) Ask the shop
where you purchased the unit when replacement of the
battery is required. 
• Built-in hard disk drives 
Hard disk drives are vulnerable to vibration. Handle
them with care. 
It is possible to damage them if they are moved while
their motors are still running. Do not move them just
after turning their power on or off (for around 30 sec-
onds). 
When hard disk drive trouble occurs, replace it immedi-
ately. Consult your dealer for servicing. 
When replacing the hard disk drives, take notice of the
following. 
• Protect the hard disk drives from static electricity. 
• Do not stack them, or keep them upright. 
• Do not use an electric screwdriver to fix them.
(Tightening torque: Approx. 0.49 N · m {5 kgf · cm}) • Avoid rapid changes of the temperature/humidity to
prevent condensation. (Acceptable change: within
15 °C/h {59 °F/h}) 
• Heat dissipation 
Refer to the following to prevent fire and malfunction of
the unit. 
• Do not block the ventilation openings in the cover to
prevent the unit from overheating. Maintain the unit
periodically to prevent dust from blocking openings. 
• Clear a space of more than 5 cm {1.97} from both
sides, the top, and the rear of the unit.
• The cooling fan is perishable. Contact your dealer
for servicing. 
• Grounding 
Confirm that the wire is connected from the SIGNAL
GND terminal to earth ground. 
A grounding connection must be made before connect-
ing the power plug of the unit to the main power supply.
When disconnecting the grounding wire, make sure that
the power plug of the unit is disconnected from the
main power supply.
• Avoid placing the unit near noise sources 
If the unit is placed near noise sources such as fluores-
cent lamps, noises may be produced. In this case,
rewire avoiding the noise sources, or move the unit to
the place far from them. 
• Places to avoid 
Do not place the unit in the following places:
• Places exposed to direct sunlight 
• Places subject to having strong vibration or impact 
• Near magnetic field sources such as a television or
speakers 
• Place where condensation forms easily, where tem-
perature changes greatly, humid places 
• Steamy and oily places such as kitchens 
• Places which are not level 
• Cleaning 
Turn the power off when cleaning the unit. Otherwise it
may cause injuries. 
Do not use strong or abrasive detergents when clean-
ing the unit body. 
Use a dry cloth to clean the unit when it is dirty. 
When the dirt is hard to remove, use a mild detergent
and wipe gently.

• Indication label
Refer to the indication label placed on the surface of
the unit as to the indications of equipment classification
and power source, etc. 
• Handle the unit with care. 
Do not strike or shake, as this may damage the unit. 
• Do not strike or give a strong shock to the unit. 
It may cause damage or allow water to enter the unit. 
• Place the unit horizontally on a level surface.
Do not place the unit in an upright position. When
stacking multiple units, clear a space of more than 5 cm
{1.97} from both sides, the top, the bottom and the rear
of the units. 
• Avoid placing receptacles that contain liquids such
as water near the unit. 
If liquid spills onto the unit, it may cause fire or an elec-
tric shock.
• Prevent condensation from forming on the surface
of the hard disk. 
If this happens, do not turn on the power of the recorder
and leave the recorder for around 2 hours. 
Wait until the dew evaporates in any of the following
cases: 
• The recorder is placed in an extremely humid
place. 
• The recorder is placed in a room where a heater
has just been turned on. 
• The recorder is moved from an air-conditioned
room to a humid and high-temperature room. 
• When the unit has not been used for a certain period,
turn on the power of the unit (approximately once a
week), and perform recording/playback to prevent
interferences with functions.
• We recommend that you make a note of your settings
and save them. This will help when you are required to
change the system configuration, or when unexpected
trouble or failure occurs.

Preface
The Network Disk Recorders WJ-ND300A is designed for use within a surveillance system.
The network disk recorder is a recording device using a hard disk drive to record pictures of network cameras instead of using
videotapes so that pictures recorded by repeated overwriting will not experience deterioration of the recorded picture quality.
Up to 32 cameras can be connected to the WJ-ND300A via a network and it is possible to record their camera pictures. It is
possible to perform the settings or operate the unit using a web browser installed on a PC when this unit is connected to a net-
work.
Features
Various Recording Functions 
• Multi-Recording 
It is possible to perform multiple recordings using a sin-
gle digital disk recorder even if the operating environ-
ments are different, for example, recording pictures of
cameras in different places with different recording
rates. 
• Schedule recording 
It is possible to perform recording automatically at a
scheduled time on a designated day of the week. It is
also possible to apply different recording settings, such
as the recording rate, by the schedule time. 
• Emergency Recording 
In the case of an emergency, emergency recordings
will be given a higher priority than other recording
modes by operating an external switch. 
• External Timer Recording 
It is possible to perform recording automatically using
an external timer. 
• Event Recording 
At an event occurrence, such as when an alarm signal
is supplied, the recording rate can be changed. 
Downloading/Transmitting Images
It is possible to download (save) the currently displayed
image in the web browser window onto the hard disk of a
PC. By establishing an FTP server, it is possible to transmit
images to a designated FTP server. When an event occurs,
it is possible to transmit images from the camera installed in
the place where the event occurred. 
Security Function and Reliability 
• Authentication function (registration of ID and pass-
word) allows users access to a predetermined selection
of the available functions. Up to 32 users can be regis-
tered. 
• If a hard disk crashes, the RAID 5 function (*1) prevents
any data loss. 
*1: To use the RAID 5 function, an optional extension
unit is required. 
Host Authentication
It is possible to restrict devices from operating this unit if
their IP addresses are not registered.
