Tracing Tone Mode
This function provides a means of tracking cables by generating one of three distinct select-
able tones on a specific wire, pair, or all pairs. The cable can be traced using a tracing probe
that is capable of detecting tones ranging from 577 Hz to 983 Hz.
The three available tones are as follows:
• HiLo1 – Fast Warble
• HiLo2 – Medium Warble
• HiLo3 – Slow Warble
To select the relevant Tracing Tone mode, first select the cable type by switching the unit
on in Network, Telephone, or Coaxial mode. Then press Tone to activate the tracing tones.
Repeated quick presses of Tone will allow you to select which wires or pairs are carrying the
tone depending upon mode. A long press of Tone (more than 2 seconds) will select the next
type of tone, "HiLo1", "HiLo2" or "HiLo3".
This screen shows, for example,
that all wires of a network cable are
carrying the "HiLo1" tone.
In this screen only wire "3" of the
telephone cable is carrying the
"HiLo2" tone.
