Safety notes
This section provides notes on using US320f safely. Read this section carefully to ensure proper and safe use of US320f.
For symbols, refer to Safety Precautions.
General
Do not use US320f for services which may directly affect human lives and for which critically high reliability is
required.
US320f is not intended to be used with or control facilities or devices impacting human lives, including medical
devices, nuclear facilities and devices, aeronautics and space devices, transportation facilities and devices, and
facilities and devices requiring high reliability. NEC assumes no liability for any accident resulting in personal injury,
death, or property damage if US320f has been used for the above applications.
Do not use US320f if any smoke, odor, or noise is present.
If smoke, odor, or noise is present, immediately turn off US320f and disconnect the power plug from the outlet.
Then contact the store where you purchased the product or your maintenance service company. Using US320f under
such conditions may cause a fire.
Do not insert wires or metal objects.
Do not insert wires or metal objects into ventilation holes or USB connectors. Doing so may cause an electric shock.
Keep water or foreign matter away from US320f.
Do not let any liquid such as water or foreign materials including pins or paper clips enter US320f. Failure to follow
this warning may cause an electric shock, a fire, or failure of US320f. If liquid or foreign matter accidentally enters
US320f, immediately turn off the power and disconnect the power plug from the outlet. Do not disassemble US320f.
Contact the store where you purchased the product or your maintenance service company.

Power supply and power cord
Do not hold the power plug with wet hands.
Do not disconnect or connect the plug while your hands are wet. Failure to follow this warning may cause an electric
shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. Failure to follow this warning may cause a gas explosion.
Do not connect or disconnect the ground wire while the power cord is connected.
Connect or disconnect the ground wire after disconnecting the power cord from the outlet.
Even if the power supply is turned off, if you touch the ground wire while the power cord is connected to the outlet,
you might receive an electric shock, or cause shorting, which could lead to fire.
Plug in to a proper power source.
Use a grounded outlet with the specified voltage. Use of an outlet with a voltage other than that specified can cause
fire or electrical leakage. Do not install US320f in any environment that requires an extension cord. Connecting to a
cord that does not conform to the power supply specifications of US320f can cause overheating, resulting in a fire.
If you want to use an AC cord set with a ground wire of class 0I, be sure to connect the ground wire before inserting
the power plug into the outlet. Before disconnecting the ground wire, be sure to disconnect the power plug from
the outlet.
Do not connect many cords into a single outlet by using extension cords.
This can cause the electric current to exceed the rated flow and overheat the outlet, which may cause a fire.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (imperfect contact) may cause a fire. Heat will also be
generated if condensation is formed on dusty blades of the halfway inserted plug, increasing the possibility of fire.
Do not unplug the power cord by holding the cable part.
Pull the power cord straight out by holding the plug. Pulling the power cord by holding the cable part or applying
extra pressure to the connector may damage the cable part, which may cause a fire or electric shock.
