<Notice>

When value of natural background radiation goes over 0.1uSv, tolerance is 25Bq/Kg.

If accuracy of value is needed, measure in lead shield box.

If it  detect same of natural background radiation level.

It will show 0.025Bq/g value as follow Japans ministry of Health, Labour and Welfare.

For more information : www.mhlw.go.jp/english/


                As Follow Japan government action, Under 25Bq/Kg of Bq value will display 0.025Bq/g.

              It automatically calculate Bq mode of back ground radiation with Bq/g mode of value.

              If user want to check raw data, Run Bq mode two times. First measurement  for 

              Back ground radiation, Second Measurement for food's raw Bq value.

Ex ) 1Kg of Mushroom value = 35Bq , Back ground radiation = 33Bq 

35Bq - 33Bq = 2 Bq/Kg.


3-3 Audio On / Off Switch.


On right side of AION-A7 is slide switch. When switch on, speaker icon appears in LCD.

When switch off, icon disappears and there would be no sound.


3-4 Battery Warning Icon. 


When battery low, this icon appears. Needs to replace battery. 

<Notice> When battery low, tolerance of measured data would be bigger than normal condition.


3-5 Auto Power off mode.


. AION - A7 has auto power off function. In CPM mode and Bq mode 90 seconds after

 detection finished, power would be off automatically. 

In CPS mode, same does in 10minutes. When power off automatically, only measured data in

Bq,  Bq/g mode would be saved.
