Laser Safety Labels
Laser Class 1M Label
Figure 1 Laser Class 1M Label
A sheet of laser safety labels is included with the laser instrument. In order
to meet the requirements of IEC 60825-1:2014, we recommend that you
stick the laser safety labels, in your language, onto a suitable location on
the outside of the instrument where they are clearly visible to anyone using
the instrument.
Please pay attention to the following laser safety warning:
Under no circumstances look into the end of an optical cable attached to
the optical output when the instrument is operational. The laser radiation
can seriously damage your eyesight. Do not enable the laser when there
is no fiber attached to the optical output connector. The laser can be
enabled by pressing the “active” button close to the optical output
connector on the front panel of the instrument or by remote control. The
laser is on when the green LED, above the optical output, on the front
panel of the instrument is lit. The use of optical instruments with this
product will increase eye hazard. The laser instrument has a built-in
safety circuitry which will disable the optical output in the case of a fault
condition. Refer servicing only to qualified and authorized personnel.
