OPERATION
Locating and Isolating Cables：
Using MT-7029 to locate and insolate cables using the 130KHz
analog, also trace twisted wires (UTP, STP, Cat 5, Cat 5e, Cat 6)
and telephone line(Cat 3). Use with a patch cord for RJ45 / RJ11
coaxial cable, general cable and various wiring boards can be tested
by using with alligator clip cable.
Warning
•It is not intended to be used on live wires with a DC power
source over DC 48V (e.g., live telephone lines), nor will it work
on wire pairs that are carrying AC signals.
•Use RJ45 SCAN compatible connector for RJ45 cable tracing.
Use RJ11(6 pin) connector for RJ11(6P/6C/4C/2C) cable tracing.
Use RJ11 (6 pin) connector and work with alligator clips for
coaxial cable, general cable and various wiring boards.
Caution
•The position on the MT-7029 lets you use the Receiver to trace
using an analog 130KHz tone. When using the Receiver to
isolate the tone source in the cable bundle or at the patch panel,
the signal might be interfered with or decreased and the signal
will not pass through metal tubes.
•It is not necessary to touch the Receiver’s tip to the cable or
patch panel when searching for the Transmitter’s signal.
•Make sure the black alligator clip of the Transmitter is connected
to the ground before use.
•When using the MT-7029 with earphone to locate and isolate
cables, please keep probe away from the earphone to avoid
interference of resonance effects
•When doing cable locating, if the signal becomes intermittent,
trailed off or interrupted, the receiver may be disturbed by the
harmonics of other devices. Please move your position for better
signal.
•Different PoE injector may cause Receiver signal to be
intermittent, trailed off or interrupted; please move your position
for better signal.
•When doing PoE scan, bigger current consumption, which will

8
decrease the battery life time, may occur according to different
PoE equipments, and it is normal.
To locate cables, do the following steps (Figure 3)：
1. Connect the black alligator clip of the Transmitter to the ground,
and then connect the red clip to a jack or punch-down block as
shown in Figure 3.
2. As the Figure 3 shown, when push , the red indicator of
“POWER/ BAT LOW” will light up and turn on the power.
SCAN : Press button for cable tracing. When the red
“SCAN” indicator lights up, the cable tracing is working.
PoE Switches SCAN : Press the button twice for PoE
switches cable tracing. When the red “PoE SCAN” indicator
lights up, the cable tracing is working.
PoE SCAN function applicable with PoE switches and network
switches.(In the cable tracing process, if the sound is weak,
perhaps cable did not connect to the PoE switches/network
switches or cable is broken, please switch to "SCAN" mode)
Press button again, stop tracing.
3. As the figure 3 shown, put the receiver function switch at "scan",
the red indicator in the middle will light up, and long press“”
on receiver to operate cable tracing function. The tracing sound
will be output from speaker. When put on the earphone, there
will be no sound from speaker, but from the earphone.
4. Use the Receiver to find the cable location from the cable rack,
patch panel, or behind the wall. The closer the cable locates, the
louder signal sound will be. The signal status indicator will
change from red to blue, and the brightness depends on signal
strength. If the blue LED indicator light is not bright, there is no
signal.
5. Adjust the volume control on the receiver to locate the wire pairs
from 0 cm to 15cm.

Figure 3 Locating cables
Isolating Cables:
To isolate the tone source in the cable bundle or at the patch panel,
do the steps as described in the previous section of “Locating
Cables”.
1. Strip the cable’s shield to a length of between 30 to 45
centimeters and divide the wires into two parts. Do the wire
separation to isolate the cables to verify the signal of each part.
If the beeper gets louder and LED lights up, you have located
the position you are looking for.
2. Adjust the volume control from high to low to locate the wire that
more difficult to be identified. Narrowing the length from 15 to 0
centimeters will help to identify the wire pairs more accurately.
3. Repeat the steps of 1 and 2 to isolate the bundled cables.
Caution
•If you cannot locate the MT-7029 signal on 2-conductor cables,
the cable may be shorted or opened. Use the Continuity Test to
check for shorts or opens on coax and non-terminated cables.
If cables are connected to the switches, it may not easy to find
the signal from MT-7029; please try to turn off the switches or
pull out the cable 1 pce a time to check the signal. If signal is still
hard to found, use " " Cable map & Shielded function or " "
Continuity function test to check cable connection.
