The instrument may only be used by trained EMC technicians
(electrical technicians)
Failure to follow this rule risks death or serious injury.
The instrument may not be used by people fitted with
electronic medical devices such as pacemakers and such
people may not enter the testing site while the instrument is
operating
The medical device may malfunction since the instrument emits more
electromagnetic wave than the regulated value.
To prevent people from being exposed to radio waves, use the
product according to the protection guidelines defined by
ICNIRP.
Do not hold the product directly with your hands.
Do not use the instrument for any purposes other than the
EMC testing purposes described in this instruction manual .
The instrument is not supposed to be used in manufacturing process of a
factory. Take an appropriate measure, such as installing the product in a
Faraday cage or shielded room, against electromagnetic noise.
The instrument may not be used in a location where fire is
prohibited or there is a risk of explosion
1. IMPORTANT SAFETY PRECAUTIONS
The "Important Safety Precautions" explain rules that must be followed to prevent any risk of
harm or injury to the user of the instrument or to other people.
Before setting up the test site, connecting the equipment, or
starting testing, please read the Chapter entitled "Basic Safety
Precautions for the Safe Use of the Simulator" which contains
additional safety advice.
※When using the product, follow the regulations on radio waves in your country/area.

5. BASIC SAFETY PRECAUTIONS
5-1. Safety Warning Signs and Their Meanings
Indicates Warning.
Failure to follow this safety information can lead to a
potentially hazardous situation resulting in death or
serious injury.
Indicates Caution.
Failure to follow this safety information can lead to a
potentially hazardous situation resulting in a minor
injury or moderate damage.
5-2. Basic Safety Precautions
1. Do not use this unit in areas where open flames are prohibited or areas having an explosive atmosphere.
Electrical discharges can occur during use, which can cause these atmospheres to ignite. (Precaution
regarding personal safety and environment)
2. Do not allow people with pacemakers or other electronic medical devices to operate this unit and to enter
the testing area while this unit is operating. Failure to observe this can result in malfunctions in the
electronic medical device and endanger personal safety. (Precaution regarding personal safety and
operation)
3. To prevent people from being exposed to radio waves, use the product according to the protection
guidelines defined by ICNIRP. Do not hold the product directly with your hands. (Precaution regarding
personal safety, operation, and environment)
4. Noise Laboratory and our affiliated dealers are not liable for any injuries or equipment damage due to
improper operation of this unit or for any resulting incidental damages. (Precaution regarding personal
safety, operation, environment, and connection)
5. When operating this unit, do not leave the equipment unmonitored. Before leaving this unit, be sure to turn off
test equipment power and terminate testing.
If you fail to observe this, you could endanger people in the surrounding area and testing equipment.
(Precaution regarding personal safety, operation, and environment)
6. Do not use or store in environments with extremely hot or cold temperatures. If you cannot maintain a
suitable operating environment (temperature: 15°C to 35°C, humidity: 25% to 75%), the unit can be
damaged and result in impaired performance. (Precaution regarding environment)
7. In the event that condensation forms, be sure that the unit is fully dried before starting operation. Failure to
observe this can damage the unit and result in impaired performance. (Precaution regarding environment)

8
8. Avoid using the unit in locations with high humidity or exposed to large amounts of dust. Failure to observe
this can damage the unit and result in impaired performance. (Precaution regarding environment)
9. Any required repairs, maintenance, and internal adjustment for this unit must be performed only by service
engineers authorized by Noise Laboratory. Failure to observe this can result in impaired performance.
10. Do not wipe the unit with thinner, alcohol, or other solvents. If the unit is dirty, wipe with a cloth dipped in
neutral detergent after it is fully wrung out. Wiping with a solvent can damage the unit surface.
11. Ensure that the product is used according to the specifications. Otherwise, the product may burn.
Do not use the product for longer time than specified. Do not input power higher than the maximum
input power specified.
