•
Do not use the tester if it operates abnormally.
Protection may be impaired.
W
To avoid disrupting network operation, to avoid
damaging the tester or cables under test, to avoid
data loss, and to ensure maximum accuracy of test
results:
•
Never connect the tester to an active network.
Doing so may disrupt network operation.
•
Never attempt to insert any connector other than
an 8-pin modular (RJ45) connector into an
adapter's jack. Inserting other connectors, such as
RJ11 (telephone) connectors, can permanently
damage the jack.
•
Never operate portable transmitting devices, such
as walkie-talkies and cell phones, during a cable
test. Doing so might cause erroneous test results.
•
To ensure maximum accuracy of copper cable test
results, perform the reference procedure every
thirty days as described under "Setting the
Reference" in Chapters 3 and 5.
Caution
•
The permanent link interface adapters may not
perform properly or may be damaged if they are
handled improperly. See page 1-20 for important
handling information.
•
Turn off the tester before attaching or removing
modules.
•
Leave the module bay covers in place when
modules are not installed. See page 1-12.
•
Never remove the memory card while the
memory card's LED is on. Doing so can corrupt the
data on the card.
•
Memory cards may be lost, damaged, or
accidentally formatted, resulting in data loss.
Therefore, Fluke Networks recommends saving no
more than one day's worth of test results on a
memory card.
