To prevent damage to the tester or cables under
test, to prevent data loss, and to make sure your
test results are as accurate as possible:
• Do not connect the tester to an active network.
Doing so causes unreliable test results, can disrupt
network operations, and can cause damage to the
tester.
• Connect to the adapters only plugs that are made
for Ethernet applications, such as RJ45, ARJ45, and
Cat 7 plugs. Other types of plugs, such as RJ11
(telephone) plugs, can cause permanent damage to
the jacks.
• To make sure your test results are as accurate as
possible, do the reference procedure every 30 days.
See “Set the Reference” on page 43.
• Do not operate portable transmitting devices, such
as walkie-talkies and cell phones, during a cable
test. Doing so can cause errors in test results.
• For permanent link adapters, do not twist, pull on,
pinch, crush, or make kinks in the cables. See Figure
10 on page 36.

To prevent possible eye damage caused by
hazardous radiation:

optical equipment emits invisible radiation that can
cause permanent damage to your eyes.
