*1 Display readings can be used as a guide for the detecting distance. When the setting value is tuned, the readout shifts. When the value exceeds “-99”, “-FF” is displayed.
*2 The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No.50.
*3 Have passed resistance tests with cleaning agents from multiple manufactures.
*4 When the response time is 10 ms
