4.Operation
4-1.Voice
WARNING: Exposure to voltage can damage the tester, immediately
disconnect the cable under test if the Voltage warning appears on the
display. Make sure the cable is not connected to any device that can
supply voltage before retesting. Do not connect two different cables
into the Voice (RJ11/12) and Data (RJ45) test ports at the same time.
The cables will interact with each other andalter test results.
1. Press ON/OFF Button to turn on the tester and then press
cc Voice Button to select the voice wire test function.
2. Connect one end the cable under test to the RJ11/RJ12 port on the
tester.
3. Connect the other end of the cable under test to the RJ11/RJ12 port
on the remote.
4. Interpret the results using the wiring and display examples on Page
13.
Note: Split may appear on the display when testing cables that have
no twisting on the pairs.

4.1.1.Using the Tone Generator to Trace a Phone Line
Note: It is necessary to use a separate amplifier probe.
1. Connect the cable under test to the RJ11/RJ12 port on the tester.
2. Press ON/OFF Button to turn on the tester and then press
c Voice Button to select the voice wire test function.
3. Press the Tone Button to activate the Tone Generator.
4. Repeatedly press the Tone Button to select the desired tone, Refer
to sequence chart forexplanation of tone selection.

4.1.2.Using the Tone Generator to Trace a Phone Line Cont
• The connector pins the tone is being sent through will be
shown on the bottom of the display.
• Repeatedly press the Cycle Button to select the desired pins.
• Refer to sequence chart below for explanation of pin selection.
Note: When tracing a cable run from the tone generator to the
end of the cable, applying the tone on a single pin will allow the
tone to be detected at a greater distance from the cable. When
trying to locate a cable in an equipment room or patch panel,
sending the tone through all 8 pins or a single pair will limit the
tone signal from spreading to other nearby cables. The tone will
be loudest when the probe tip is placed directly on the wires the
tone is being sent through at the end of the cable. When sending
a tone through a single pair, verification can be made by shorting
the suspected pair. The tone will be very faint when the pair the
tone is being sent through is shorted.

• The remote ID’s can be used to identify cable runs from
the patch panel to a wall port.
• Each identifier has a labeled ID number.
• When the tester is connected to a cable that has an
identifier attached at the other end, the tester will display
the ID number that is marked on the identifier.
1. Connect the numbered remote ID’s to the port for each
cable that needs to be identified.
2. At the wiring closet or patch panel, connect the unknown
cable to the RJ45 port on the tester.
3. Press ON/OFF Button to turn on the tester and then
press Data Button to select the data wire test
function.
4. If the cable being tested is connected to one of the
remote ID’s,the display will indicate the number that
corresponds to the remote.
Note: The RJ45 remote ID’s do not test the wiring on the cable. Only the
remote can identify wiring faults. The remote may not identify the cable if
the cable is miss-wired.
