Protection may be impaired.
WCaution
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.
• 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.
