injury if the system is mishandled ignoring the message given with this sign.
Caution
This sign gives a message assuming possible human injury or property
damage if the system is mishandled ignoring the message given with this
sign.
The △symbol shows a message (including a warning) that must be paid attention to. The
specific precaution is shown by picture or text near or in the △. The message given in the
left-hand picture calls attention to "electrical shock."
symbol shows a prohibition (prohibited action). The specific precaution is shown by picture
or text near or in the . The message given in the left-hand picture prohibits "disassembly."
● symbol shows a mandatory message (action that must be taken without exception). The
specific precaution is shown by picture or text near or in the ●. The message given in the
left-hand picture instructs the user to "remove the power plug from the receptacle."
Warning
Continuing to use the system with unlikely
abnormalities such as smoke and abnormal smell
and sound may cause fire and electric shock.
After turning off the power of the system's main
unit immediately, be sure to remove the power
cable plug from the receptacle. After confirming
that no more smoke is coming out, contact our
sales office for a repair request. Do not attempt to
repair the system by yourself, as it is dangerous
for the user.
Should water or foreign materials enter the
system, after turning off the power of the system's
main unit immediately, remove the power cable
plug from the receptacle, and then contact our
sales office. Continuing to use the system with
foreign materials inside may cause fire or electric
shock.
If cables are damaged such as when the power
cable is broken to disconnection and cores are
exposed, contact our sales office for a repair.
Otherwise, it may cause fire or electric shock.
Do not use the system in a place where liquid may
splash on the system's main unit directly.
Otherwise, it may cause fire or electric shock.
Use the system only within the voltage range
specified in the Instruction Manual. Otherwise, it
may cause fire or electric shock.
Fully insert the power cable plug into the power
receptacle. Otherwise, it may cause fire or electric
shock.
Do not place heavy objects on the power cable.
Also make sure that the power cable is not caught
under the system. Otherwise, the cable may be
damaged and cause fire or electric shock.
Do not place flower vases, cups, containers with
water, or small metal items on the system. If water
spills or enters the inside, fire or electric shock
may be caused
Do not damage, process, bend forcefully, twist,
pull, or heat the power cable, Otherwise, the cable
may be damaged and cause fire or electric shock.
Never disassemble, repair, or modify the main
unit. Also, never remove the cover. Otherwise, it
may cause fire or electric shock.

Caution
When disconnecting the power cable, do not pull
the cable. Instead, be sure to hold the power plug
to disconnect it. Otherwise, the cable may be
damaged and fire or electric shock may be
caused.
Before caring for the system, remove the power
plug from the receptacle for the sake of safety.
Otherwise, it may cause electric shock.
Before moving the system, turn off the power
switch, and be sure to remove the power plug
from the receptacle, and then remove the
connection cords of the external devices.
Otherwise, cords may be damaged and fire or
electric shock may be caused.
Do not place the power cable near heat
generating devices. This may melt the covering of
cable and may cause fire or electric shock.
Do not connect/disconnect the power plug with
wet hands. Otherwise, it may cause electric
shock.
Before turning on the power, turn the volume to
minimum. Otherwise, you will hear a loud sound
suddenly, which may cause impairments such as
a hearing loss.
Do not connect/disconnect the power plug with
the power switch on. This may cause system
malfunctions.
Do not connect/disconnect the module unit and
the card unit with the power switch on. This may
cause system malfunctions.
Do not put the module unit and the card unit in
places where it is susceptible to static electricity
(such as on a carpet), This may cause system
malfunctions.
If the panel surface becomes dirty, wipe it off
using a soft cloth immersed in a small amount of
neutral detergent. Never use gasoline, alcohol,
cleanser, or freon.
The module unit and the card unit were adjusted
when installed.
Please know that if changes are made by the
customer after delivery such as replacing parts or
adjusting the internal trimmer, maintaining of the
performance afterward cannot be guaranteed.
Install the system on a flat surface with good
ventilation. Otherwise, the internal temperature
may rise to cause system malfunctions.
Do not use in places where corrosive gas is
generated. There is a possible cause of the
malfunction or failure.
Do not use, expose, or store batteries in
high-temperature locations such as direct sunlight
or in the car in the hot sun. There is a risk of
leakage, overheating, explosion, or fire of the
battery. Also, please do not throw in fire or heat.
There is a danger of explosion if you replace the
battery by mistake. Please exchange with the
same or equivalent type.
For protection from electric shock, please plug the
power cable plug into an outlet with a protective
earth terminal correctly connected to earth. Using
it without connecting a protective earth may cause
electric shock.
Place it in a location that is easily accessible to the
power plug. If you feel abnormal, immediately turn
off the power and unplug the power plug from the
outlet. Also, even when the power is turned off, a
small current flows. Always unplug the power plug
from the outlet when not using this product for a
long time. When installing this equipment in
system, please construct a system that can be shut
off with a breaker or the like.

Disposing of this Equipment
When disposing this equipment, contact an authorized industrial waste disposal operator to
handle the disposal since this equipment needs to be disposed as an industrial waste.

Since the consumable parts including fans tend to
lose their effectiveness with frequency and time of
use, replacement is needed according to
consumption. We recommend carrying out a
periodical maintenance. For repair or maintenance,
consult with our sales representatives or service
department shown on the end of this manual.
TAMURAowes no responsibility or liability for any
failure due to improper use or alteration.

Precautions on Installation of NT MATRIX
Install NT MATRIX with special care to ventilation according to the following precautions:
1) Do not block ventilation holes and fans.
2) When you embed NT MATRIX in a table or desk, use a structure in consideration of air flow.
3) When you stack NT MATRIX mounted on a rack, prevent thermal influence from equipment installed below it.

7-1-6 DSP CARD SLOT
There are two slots for DSP CARDs. By default, one DSP CARD is preinstalled in the PRIMARY
DSP slot.
To use redundant configuration of DSP CARDs, mount an additional DSP CARD (optional) in the
SECONDARY DSP slot.

7-1-7 Connection of DSP CARDs with NT MATRIX Manager and CUSTOM UI
To use the NT MATRIX Manager application or CUSTOM UI application, connect DSP CARD(s) to a
computer on which the NT MATRIX Manager application or CUSTOM UI application is installed,
using a LAN cable of CAT5E or higher.
If Primary DSP is ACT (running), connect with Primary DSP with LAN cable.
If the Secondary DSP is ACT (running), connect with the secondary DSP with a LAN cable.
Note: If the DSP CARD is composed of two boards and the DSP CARD of the ACT switches from
Primary to Secondary, it is necessary to change the connection of the LAN cable.
[Connection with a computer: One DSP CARD configuration]
[Connection with a computer: Two DSP CARD configuration Primary DSP CARD =ACT]
