CAUTION – LASER SAFETY
The laser used in the Renishaw NC4 non-contact tool setting system emits visible red light at a wavelength
of 670 nm and has a power output of less than 1 mW.
The NC4 is classied as a Class 2 laser product as dened by BS EN 60825-1:2014.
Complies with 21 CFR 1040.10 and 1040.11 except for conformance with IEC 60825-1 Ed. 3., as
described in Laser Notice No. 56, dated May 8, 2019.
BS EN 60825-1:2014 directs to attach a laser warning label and explanatory label.
A warning label and explanatory label are permanently xed to each side of the transmitter (Tx) housing
