Whenever any of the EF, MF or RF radiation intensities reaches the
medium level (" " appears), the yellow indicator LED will light up.

the buzzer will sound.
Move the tester a little left and right and change the tester's direction,
the tester may changeits radiation intensity indication. The highest
reading displayed during the detection is the most accurate
