1) Press the power switch, the default measurement gear level of LCD display
microprocessor is 40~90 dB. And the measured onsite sound level will display
within this range. If one of the "UNDER" or "OVER" characters displays on the
LCD, it means that onsite sound is either lower or higher than the limit range
of 40 ~ 90 dB. At this time, the measurement value is not accurate, you should
