To avoid possible eye damage caused by
hazardous radiation and to avoid possible fire,
electric shock, or personal injury:
Never look directly into optical connectors. Some
sources produce invisible radiation that can
permanently damage your eyes.
Never run any tests that activate the tester’s
outputs unless a fiber is attached to the output.
Do not open the case; no user-serviceable parts
are inside.
Do not modify the tester.
Do not use magnification to view the optical
outputs without proper filtering.
Use of controls, adjustments, or procedures not
stated herein might result in hazardous radiation
exposure.
Use only ac adapters approved by Fluke Networks
for use with the OptiFiber tester to charge the
battery or power the tester.
Do not use the tester if it is damaged. Inspect the
tester before use.

If this equipment is used in a manner not specified
by the manufacturer, the protection provided by
the equipment may be impaired.
To avoid damaging the tester or cables under test
and to avoid data loss:
Always turn the tester off before removing or
installing a module.
Never connect the OTDR port to an optical source.
Doing so can damage the OTDR receiver.
Never connect the tester to an active network,
except when using the power meter. Doing so
causes unreliable test results and can disrupt
network operations.
If the tester shows an error because the power
reading is too high, immediately disconnect the
source from the tester. The tester is not designed
for measuring higher power levels, such as
produced by CATV, optical amplifiers, and cellular
systems.
Avoid touching reflective surfaces (such as metal)
to the end of a fiber cable plugged into the OTDR
when the OTDR is operating. An open fiber
connector endface has about a 4% reflection.
