Note on IEC825/EN60825 Class 1

IEC825/EN60825 Class 1 is an international laser safety standard that limits the amount
of energy emitted by the laser over a period of time. IEC825/EN60825 Class 1 limits the
duration of laser scanner on-time, using an emission accumulator mechanism.
To conform to IEC825/EN60825 Class 1 standards, the laser cannot be on for more than
60 seconds in a 1000-second time period. The terminal accumulates scan time while it is
scanning bar codes, up to the maximum 60 seconds.
When it runs out of available scan time, the terminal emits a long, low-tone beep. When
2 seconds of scan time become available, the system emits another long, high-frequency
beep. Refer to the Series 3000 Application Programmer's Guide for more information.
