4.2 General Specification
Safety: This instrument is designed for testing
fibre optic installations and so meets the safety
requirements of IEC 60825-1: 1994 (including
amendment A11: 1996) and IEC 60825-2: 1995
(including amendment A1: 1998). This product's
output levels are within the Accessible Emission
Limits (AEL) for a Class 1 Laser Product and so does
not generate any optical hazards internally.
