Open the battery box and install battery.
Holding the back of this tester, let antenna of tester alignment/target face to what you want to test, such as TV, computer, energy saving lamp, etc...If test mobile phone, you should put antennas of mobile phone and radiation tester together, then dial-up.
The screen will show the radiation strength, if radiation is more, the numbers will be more. Unit of radiation is Ux/cm2, this is relative value.
Then put our anti-radiation sticker cover antenna of mobile phone, dial up again and test radiation value. You will find the number value is much lower.
After finishing test, power off the machine. 

Notice:
Usually, antenna is on the back of mobile phone, top-right back or top-left back, you need find it and stick at correct place. You can use test to find where is the antenna during dialing.

As this machine is for testing strength of electronic charge and electromagnet fields, so it can't be used under high-temperature status, environment with carpets and strong magnet.
In our life room, there are TV, Mobile phone, broadcast, interphone, repeater station etc, which effect the normal testing.
Hold the back of test, but not close to it, when number value get to stable but some pulse, for an example 635-827, this is normal. Because radiation is not stable in the same time.
It use 9V 6F22 battery, if the number value is very small or alarm is very low, please change battery.
