Safety Precautions
Please follow the following safety rules:
• Do not remove instrument covers when operating.
• Ensure that the instrument is switched off throughout the cleaning procedures.

may result in hazardous radiation exposure.
• Make sure that you disable all sources when you are cleaning any optical interfaces.

outputs when the device is operational. The laser radiation is not visible to the human
eye, but it can seriously damage your eyesight.
