The following general warning and cautions are applicable to this instrument:
WARNING
Before operating the Model 6100 Laser Diode and Temperature
Controller, please read and understand all of Sections 1 thru 4.
WARNING
Do not attempt to operate this equipment if there is evidence of
shipping damage or you suspect the unit is damaged. Damaged
equipment may present additional hazards to you. Contact
Newport technical support for advice before attempting to plug
in and operate damaged equipment.
WARNING
To avoid electric shock, connect the instrument to properly
earth-grounded, 3-prong receptacles only. Failure to observe
this precaution can result in severe injury.
WARNING
Before cleaning the enclosure of the Model 6100 Laser Diode
and Temperature Controller, the AC power cord must be
disconnected from the wall socket.
CAUTION
