Warning
To avoid the risk of injury or death,
always observe the following precautions before initializing the unit:

Never look into the end of an optical cable connected to an optical output device that is operating. Laser radiation is
invisible, and direct exposure can severely injure the human eye.

Eye and skin exposure to direct or scattered laser radiation is hazardous and is considered potentially extremely
harmful.

Install the laser in an enclosed area with access restricted to trained personnel. Clearly label the area and mark the
entrance with the class of laser (Class II, IIIa, or IIIb).

Never leave the laser on and unattended.

If the laser has a key switch on the power supply front panel, the key must be inserted and turned to enable the laser
to operate. The key is captive in the operational position. Remove the key from the laser when not in use or
unattended. Store the key in a safe place.

Limit access to the laser to personnel who are familiar with the equipment. Ensure that the laser is not assembled,
operated, or repaired by inexperienced or untrained personnel.

Ensure that all mirrors and optics used are securely positioned and fixed to prevent movement. Prevent stray
reflections from surfaces at all times.

Do not allow reflective objects to be placed in the laser beam. Laser light scattered from a reflective surface can be as
damaging as the original beam. Objects such as rings, watchbands, and metal pens or pencils can be hazardous.

Install the laser so that the laser beam is not at eye level.

Terminate the laser beam path with a suitable power meter or non-reflecting beam stop. Enclose beam stops where
possible. Consult a power meter or the beam stop manufacturers’ operating manual for proper usage.

Suitable eye protection must be worn at all times when laser output is possible.

Connect the power cord only to a power outlet equipped with a protective earth contact. Never connect to an
extension cord that is not equipped with this feature.

Do not interrupt the protective earth grounding. Any such action can lead to a potential shock hazard that can result in
serious personal injury.

Disconnect the power cord from the unit before adding or removing any components. Do not rely on electrical safety
devices or interlocks.

Some electrical components within the products may maintain electrical charge even when unplugged.

After unplugging products from the ac mains, wait a minimum of 1 minute before disconnecting the laser head from
the power supply. The emission indicator on the power supply should be off.

WARNING: When disconnecting a laser head from a power supply there may be a residual charge remaining within
the laser head and present at the exposed tips of the HV connector. Release any excess charge by shorting the tips
of the connector to a metal surface before additional handling.

Do not use the unit outdoors. To prevent potential fire or shock hazard, do not expose the unit to any source of
excessive moisture.

Operating the unit in the presence of flammable gases or fumes is extremely hazardous.

Never remove covers or panels from the units.

Do not perform any operating or maintenance procedure that is not described in the user’s manual.
