Safety precautions

The following cleaning instructions contain some general safety
precautions, which must be observed during all phases of
cleaning.
Please try, whenever possible, to use physically contacting
connectors, and dry connections. Clean the connectors,
interfaces, and bushings carefully after use.
If you are unsure of the correct cleaning procedure for your
optical device, we recommend that you first try cleaning a
dummy or test device.
Keysight Technologies assumes no liability for the customer is
failure to comply with these requirements.
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.
