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.
