active.
（10）Carry out commissioning, calibration and focusing at low output
power and then increase the output power gradually when the calibrating
and focusing work is done.
（11）If the equipment is operated in a manner not specified in this
document, the protection devices and performance of the equipment may
be impaired and the warranty will be voided.
CAUTION :
◎ The output of the laser is delivered through a lens with an anti-reflection
coating. If the backward-stage light path of your laser has the optical lens,
please strictly inspect the lens of the output head and the backward-stage
lens of the laser, and ensure that there is no dust and any other impurity
on the lens. Please note that any macroscopic attachment may cause
extreme damage to lens or burn the laser or any backward-stage light
path equipment.
◎ For cleaning instructions of the lens, please refer to the "Optical Fiber
Connector Inspection and Cleaning Guide".
◎ Hot or molten pieces of metal may be produced when the laser is under
operation. Exercise caution if debris is produced in operation.
◎ When implement commissioning and calibration of laser output, it’s
necessary to set the quality of the spot emitted from the laser at low
power levels via an infrared viewer, and then gradually increase the output
power.
WARNING :
◎ Make sure that the individual protective equipment meets the output
power and wavelength range of the laser.
◎ Never look directly into the optical fiber or the collimator, and make sure
