!WARNING – Trace only unenergized wiring. Contact with live
circuits can result in severe injury or death. Always disconnect power
to the circuit prior to using the ToneProbe.
Tracing Pairs
1. Turn the upper transmitter
knob to ‘Tone’.
2. Turn the lower transmitter
knob to either ‘A’, ‘B’ or ‘C’.
3. Connect the red transmitter
lead to one wire in the pair and
connect the black transmitter
lead to the other wire.
4. Activate the receiver by
pressing and holding the
‘Push On’ button.
5. At the opposite end of the wire, move the receiver tip near each
pair. The pair with the loudest tone is the intended pair.
Tracing Cables
1. Turn the upper transmitter
knob to ‘Tone’.
2. Turn the lower transmitter
knob to either ‘A’, ‘B’ or ‘C’.
3. Connect the red transmitter
lead to:
a. A wire in the unknown
cable for cables with
multiple wires.
b. The outer shield for a
tracing a shielded/coaxial cable.
4. Connect the black transmitter lead to:
a. Another wire in the unknown cable but not in the same pair
or to ground for cables with multiple wires.
b. The center conductor or ground for a tracing a shielded/
coaxial cable.
5. Activate the receiver by pressing and holding the
‘Push On’ button.
6. Move the receiver tip towards a section of the wall where the
cable could be behind. Where the tone is the loudest indicates
the location of the cable.
Tracing Telephone Wiring
1. Insert the RJ-11 plug from the
transmitter into the telephone
jack.
2. Turn the upper transmitter
knob to ‘Tone’.
3. Turn the lower transmitter
knob to either ‘A’, ‘B’ or ‘C’.
4. Activate the receiver by
pressing and holding the
‘Push On’ button.
5. Trace the wire by following the audible and visual signal the
receiver creates.
* Tracing Tip 1: Interference can affect the accuracy of telephone
line tracing. Locate the junction box and disconnect the
house line from the main telephone service line to prevent
interference. Note each location of the wires disconnected so
proper installation occurs after tracing is complete.
Tracing Data/LAN Wiring
1. Insert the RJ-11 plug from
the transmitter into the data/
LAN jack.
2. Turn the upper transmitter
knob to ‘Tone’.
3. Turn the lower transmitter
knob to either ‘A’, ‘B’ or ‘C’.
4. Activate the receiver by
pressing and holding the
‘Push On’ button.
5. Bring the receiver near the transmitter to verify proper function
through audible and visual signals.
6. Trace the wire by following the audible and visual signal the
receiver creates.
* Tracing Tip 1: Interference can affect the accuracy of data/LAN
line tracing. Disconnect all connections from any outside source
to the data network.
* Tracing Tip 2: Due to physical shielding properties of the LAN
cable to prevent interference, the receiver must contact the LAN
conductor wire and is stronger along one side of the wire.
Tracing Other Wiring
1. Single Wire
a. Turn the upper transmitter knob to ‘Tone’.
b. Turn the lower transmitter knob to either ‘A’, ‘B’ or ‘C’.
c. Connect the red transmitter lead to the wired being traced.
d. Activate the receiver by pressing and holding the
‘Push On’ button.
e. Trace the wire by following the audible and visual signal
the receiver creates.
* Tracing Tip: Connect the black transmitter lead to suitable
ground to boost the signal.
2. Two Wires
a. Turn the upper transmitter knob to ‘Tone’.
b. Turn the lower transmitter knob to either ‘A’, ‘B’ or ‘C’.
c. Connect the red transmitter lead to one wire and the black
transmitter lead to the other wire being traced.
d. Activate the receiver by pressing and holding the
‘Push On’ button.
e. Trace the wire by following the audible and visual signal
the receiver creates.
Testing for Continuity
1. Connect the red transmitter lead to one wire.
2. Connect the black transmitter lead to the other wire.
3. Turn the upper transmitter knob to ‘Cont’.
4. If there is DC continuity between the wires, the continuity LED
with glow green.
Tracing Multiple Wires/Cables
Utilize multiple transmitters and the 3 different available tones
(A, B, C) for multi-line identification.
BATTERY REPLACEMENT
Both the transmitter and
receiver have and LED that
turns yellow to indicate a low
battery.
1. Receiver: Turn the receiver
over and locate the screw
holding on the battery door.
Remove the screw, open
the door and replace with a
new 9V battery.
2. Transmitter: Turn the unit
over and locate the BOTTOM
screw holding the battery
door in place. Remove the
bottom screw, slide the door
down and replace with a
new 9V battery.
