1. IMPORTANT SAFETY PRECAUTIONS
The "Important Safety Precautions" explain rules that must be followed to prevent any risk ofharm or injury to the user of the instrument or to other people.

 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 withelectronic medical devices such as pacemakers and suchpeople 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 theproduct according to the protection guidelines defined byICNIRP.
Do not hold the product directly with your hands.

 Do not use the instrument for any purposes other than theEMC testing purposes described in this instruction manual.
The instrument is not supposed to be used in manufacturing process of afactory. 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 isprohibited or there is a risk of explosion

Before setting up the test site, connecting the equipment, orstarting 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.

Basic Safety Precautions

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. (Precautionregarding 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 theelectronic medical device and endanger personal safety. (Precaution regarding personal safety andoperation)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 toimproper operation of this unit or for any resulting incidental damages. (Precaution regarding personalsafety, 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 asuitable operating environment (temperature: 15°C to 35°C, humidity: 25% to 75%), the unit can bedamaged 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 to7

observe this can damage the unit and result in impaired performance. (Precaution regarding environment)
8.

7. MEASUREMENT OF VSWR CHARACTERISTIC
The product allows you to measure VSWR characteristics using a network analyzer. By measuring
the VSWR of the product and comparing it with the reference characteristics, you can check thecharacteristics of the product.
【Caution】】
・Connect
Connect a highhigh-frequency,frequency, coaxial cable that supports high frequencies up to 6 GHz.
・Use
Use the product upright with a distance of at least 1 m from any wall, ceiling, and metal body on thefloor.
Do not touch the product or coaxial cable during a calibration process.
・Do・Depending
Depending on the type and length, the coaxial cable may affect the VSWR characteristics of theproduct, resulting in nonconformance to the specifications.

8. OPERATION
Connect a coaxial cable to the SMA connector side of the product. When connecting the coaxial
cable to the product, use a torque wrench to tighten the SMA connector with a torque ofapproximately 0.57 N·N·m.
The product is a linear
linear-polarizedpolarized antenna. Horizontally or vertically apply the product to a desired
area. The area indicated as High Radiation Area radiates strongest electromagnetic waves. ApplApplyy

Use of NKU2460G
2460G※DoDo not hold the product directly with your hands. Doing so may affect the characteristics as well as
expose you to electromagnetic waves exceeding the protection
protection-guideline
guideline value defined by ICNIRP.
Use an optionally available flexible antenna handle (02-0015400154A).

Ensure that the product is used according to the specifications. Otherwise, the product may burnor the characteristics of it may be affected.

Depending on the environment, the continuous use of the product for a long time may cause the productto become hot and burn even if the specifications are met. If this is the case, stop using the product andcool it before resuming the use of it. If the antenna becomes hot, the area surrounding the feeding poipointnt
mainly generates the heat. The feeding point is as shown below.

Area surrounding the feeding point
Pay extra care not to suffer a burn due to high temperatures.
