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.
• Use of controls or adjustments or performance of procedures other
than those specified may result in hazardous radiation exposure.
• Make sure that you disable all sources when you are cleaning any
optical interfaces.
• Under no circumstances look into the end of an optical device attached
to optical outputs when the device is operational. The laser radiation is
not visible to the human eye, but it can seriously damage your eyesight.
• To prevent electrical shock, disconnect the instrument from the mains
before cleaning. Use a dry cloth, or one slightly dampened with water,
to clean the external case parts. Do not attempt to clean internally.
• Do not install parts or perform any unauthorized modification to optical
devices.
• Refer servicing only to qualified and authorized personnel.
