Introduction
The Schneider Electric Thorsman Multi-function Cable Tracer, Model IMT23106, is a versatile tool designed for professionals and enthusiasts to efficiently trace and identify cables, wires, and lines. This device functions as a wire tracker and tone generator, making it ideal for locating cables within walls, under floors, or in bundles. It is suitable for use with coaxial cables, telephone lines, and DC automotive wires.

What's in the Box
- 1 x Schneider Electric Thorsman Multi-function Cable Tracer (Transmitter and Receiver)
- 1 x Instruction Leaflet
- 2 x 1.5V AAA Batteries (for Transmitter)
- 4 x 1.5V LR44 Batteries (for Receiver)
Setup
Battery Installation
The cable tracer requires two types of batteries for its transmitter and receiver units.
- Transmitter Unit: Locate the battery compartment on the back of the main transmitter unit. Insert 2 x 1.5V AAA batteries, ensuring correct polarity.
- Receiver Unit: Locate the battery compartment on the receiver (pen-like) unit. Insert 4 x 1.5V LR44 batteries, ensuring correct polarity.
Note: Always use new batteries of the specified type for optimal performance. Remove batteries if the device will not be used for an extended period.

Operating Instructions
Basic Cable Tracing
- Connect Transmitter: Connect the transmitter unit to the cable or wire you wish to trace. This can be done using the integrated connectors or the provided crocodile clips for bare wires or terminals.
- Activate Transmitter: Turn on the transmitter unit. It will generate a tone signal onto the connected line.
- Use Receiver: Turn on the receiver unit. Hold the receiver near the suspected path of the cable. The receiver will pick up the tone signal.
- Locate Cable: Move the receiver along the path where you believe the cable runs. The tone will be loudest and the LED indicator on the receiver will illuminate most brightly when you are directly over the cable.

Identifying Cables in Bundles or Panels
When dealing with multiple cables, the tone generator and receiver can help identify a specific line.
- Connect the transmitter to the known end of the cable you want to identify.
- At the other end, or within a bundle of cables, use the receiver to individually scan each cable.
- The cable emitting the tone, indicated by the receiver's audio feedback and LED, is the one connected to the transmitter.

Visual Indicator (LED)
The receiver unit features an LED indicator that provides a visual cue when a tone is detected. The brightness of the LED corresponds to the strength of the signal, helping to pinpoint the exact location of the cable.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the cable tracer in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries when the performance degrades or the LED indicator on the receiver becomes dim. Always dispose of used batteries responsibly.
Troubleshooting
- No Tone/Weak Signal:
- Check if batteries in both transmitter and receiver are correctly installed and have sufficient charge. Replace if necessary.
- Ensure a proper connection between the transmitter and the cable being traced.
- Verify that the cable is not live or connected to an active power source, as this device is not designed for live circuit tracing and can interfere with the signal.
- Reduce the distance between the transmitter and receiver, or the depth of the cable.
- False Readings/Interference:
- Electromagnetic interference from other electrical devices or power lines can affect accuracy. Try to trace in an area free from such interference.
- Ensure the receiver is held perpendicular to the cable path for best signal reception.
- Receiver LED Not Illuminating:
- Check receiver battery.
- Ensure the receiver is turned on.
- The signal might be too weak to trigger the LED. Rely on audio feedback if present.
