CHAPTER 2: Introduction
2.3 Warnings/Cautions
WARNING
Do not attach the LAN Solution Network Tester to primary
power lines. The tester may be damaged and cause a
safety hazard. When connecting to an unknown jack or
plug, the tester should be off. Once connected, press the
CABLE button to ID the connection.
CAUTION
Improperly crimped, damaged, or uncrimped plugs can
damage the LAN Solution Network Tester’s jack. Inspect
plugs for proper termination and crimping before inserting
anything into the tester. Plug contacts should always be
recessed into the plastic grooves. Do not use with standard
6-position plugs (RJ-11/RJ-12). This might damage the
tester. Use the provided “no fault” (green transparent plugs)
6-position RJ cable, which can be connected to a 6- or 8-
position jack without causing any damage.
NOTE
The screen comes with a clear, peel-off protective coating
over the LCD screen. Remove it for the clearest view of the
