Laser Safety Labels
Laser class 1M label
A sheet of laser safety labels is included with the laser module as
required. In order to meet the requirements of IEC 60825-1 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
W A R N I N G Please pay attention to the following laser safety warnings:
• Under no circumstances look into the end of an optical cable
attached to the optical output when the device 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 is enabled by pressing the gray button close to the optical
output connector on the front panel of the module. The laser is on
when the green LED on the front panel of the instrument is lit.
• The use of the instruments with this product will increase the
hazard to your eyes.
• The laser module has 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.
