Electric shock hazard:
Contact with live circuits could result in
severe injury or death.
CAUTION
LASER LIGHT
DO NOT STARE INTO BEAM
CLASS I LASER PRODUCT
The 580XL instrument is a laser device conforming to the require-
ments of CDRH, CFR 1040, Subchapter J. While there is no potential
for eye damage due to unaided direct exposure, users should always
avoid looking directly into the output port. The use of optical viewing
instruments, such as microscopes, magnifiers, etc., should always be
avoided. The use of such devices around active fibers can focus an
intense beam of light energy onto the retina of the eye, which can
result in permanent damage.
Laser hazard:
• When performing measurements on fiber optic systems, avoid
eye exposure to any open-ended fibers, optical connectors,
optical interfaces, or other sources because they may be con-
nected to active laser transmitters.
•Do not look into the optical port when a source is turned on.
• Avoid looking at the free end of a test fiber, i.e., the end not
connected to the instrument. If possible, direct the free end
toward a non-reflective surface.
Failure to observe these precautions may result in injury.

• Do not open the case of the unit for any reason. It contains no
user-serviceable parts.
• Use this unit for the manufacturer’s intended purpose only, as
described in this manual. Any other use can impair the protec-
tion provided by the unit.
Failure to observe these precautions may result in injury and may
damage the unit.
Instrument damage hazard:
• Do not leave the unit in direct sunlight or near direct sources of
heat.
• Protect the unit from strong impacts or shock.

General Information
This section provides general instructions on how to use the XL
fiberTOOLS instruments.
If circumstances require that the instruments be serviced and main-
tained in-house, contact Greenlee for technical assistance.
Battery Installation or Replacement
All XL fiberTOOLS instruments are powered by two AA-size 1.5 volt
alkaline batteries. Two batteries are shipped with the instruments and
must be installed before the units can be used.
Note: Regular zinc-carbon batteries are not recommended for use in
XL fiberTOOLS instruments. Use of such batteries, often marked
“heavy duty,” will shorten the operating time.
Operating times for the XL fiberTOOLS instruments covered in this
manual are listed in the “Specifications” section.
LED and Laser Sources
One of the front panel LED indicators will blink when the batteries are
low. The instrument may continue to be operated until the front panel
LED shuts off. However, the light output may become unstable after
the power drops past this “low battery” threshold.
Optical Power Meters
Low battery status is indicated by a “B” annunciator appearing in the
upper left-hand corner of the LCD screen. After the “B” appears, the
unit may be operated for a minimum of five hours before the batteries
are depleted.
