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 "
Continuity function test to check cable connection.
