3. Setup
3.1 Battery Installation
- Locate the battery compartments on both the Tone Generator (transmitter) and the Inductive Amplifier Probe (receiver).
- Open the battery covers.
- Insert the provided 9V batteries, ensuring correct polarity (+/-).
- Close the battery covers securely.
3.2 Connecting the Transmitter
The Tone Generator (transmitter) can be connected to the circuit or cable you wish to test using its integrated test leads:
- Alligator Clips: For direct connection to exposed wires or terminals.
- RJ11/RJ45 Connector: For testing network or telephone cables.
3.3 Powering On
Turn on the Tone Generator by sliding the switch to either 'TONE' or 'CONT' (Continuity) mode. The Inductive Amplifier Probe is activated by its spring-loaded ON/OFF button.

4. Operating Instructions
4.1 Wire Tracing (Tone Mode)
This mode is used to identify and trace wires within bundles, walls, or conduits without damaging insulation.
- Connect the Tone Generator to the wire or circuit you wish to trace. Ensure the switch is set to 'TONE'.
- Turn on the Inductive Amplifier Probe by pressing its spring-loaded ON/OFF button.
- Adjust the volume sensitivity control on the probe to a suitable level.
- Place the carbon fiber tip of the probe near the suspected wire path.
- Listen for the audible tone emitted by the probe. The tone will be loudest when the probe is directly over the energized wire.
- Follow the path of the wire by moving the probe along the loudest tone.

4.2 Short Circuit Testing (Continuity Mode)
To test for short circuits or continuity:
- Connect the Tone Generator to both ends of the wire or circuit. Set the switch to 'CONT'.
- If the circuit is continuous (no break or short), the green 'CONT' LED on the Tone Generator will illuminate.
- If there is a short circuit, the red 'TONE' LED may also illuminate or behave erratically, depending on the nature of the short.
4.3 Clear/Busy/Ringing Identification
When connected to a telephone line, the Tone Generator can help identify the line status:
- Clear: Indicates an idle line.
- Busy: Indicates an active call.
- Ringing: Indicates an incoming call.

5. Maintenance
5.1 Battery Replacement
Replace the 9V batteries in both units when the indicator lights dim or the tone becomes weak. Always use fresh 9V batteries for optimal performance.

5.2 Cleaning and Storage
Wipe the units with a dry, soft cloth after each use. Do not use abrasive cleaners or solvents. Store the kit in its organizer bag in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
- No Tone/Weak Signal:
- Check if batteries are correctly installed and have sufficient charge. Replace if necessary.
- Ensure the Tone Generator is switched to 'TONE' mode.
- Verify proper connection of the Tone Generator to the circuit.
- Adjust the volume sensitivity on the Inductive Amplifier Probe.
- No Continuity Indication:
- Ensure the Tone Generator is switched to 'CONT' mode.
- Check for breaks or open circuits in the wire.
- Verify secure connections of the test leads.
- Erratic Readings:
- Ensure the probe tip is not accidentally shorting out against other wires or metal surfaces.
- Reduce the sensitivity if interference from nearby electrical fields is suspected.
