5. Setup and Battery Installation
5.1 Battery Installation
- Locate the battery compartments on both the main transmitter unit and the receiver unit.
- Open the battery covers.
- Insert one 9V 6F22 battery into each unit, ensuring correct polarity (+/-).
- Close the battery covers securely.
5.2 Initial Power On
Turn on both the transmitter and receiver units using their respective power switches. The LED indicators should illuminate briefly, indicating the devices are ready for operation.
6. Operating Instructions
6.1 Cable Tracing (Wire Tracking)
This function helps locate a specific cable within a bundle or wall.
- Safety First: Before tracing metallic wires, ensure all power to the cables is disconnected to prevent damage to the device.
- Connect the RJ45 or RJ11 cable from the transmitter to the cable you wish to trace. For non-standard cables, use the RJ11 alligator clip cable.
- Turn on the transmitter unit.
- Turn on the receiver unit and adjust the volume knob to a comfortable level.
- Move the receiver's probe along the suspected path of the cable. The receiver will emit an audible tone, which will be strongest when the probe is directly over the target cable.
- Use the LED flashlight on the receiver for better visibility in dark areas.

6.2 Network Cable Testing (RJ45/RJ11)
This function checks for open circuits, short circuits, wiring faults, and reversed connections in network cables.
- Connect one end of the RJ45 or RJ11 cable to the transmitter's corresponding port.
- Connect the other end of the cable to the receiver's corresponding port.
- Turn on both units.
- On the receiver, select the "TEST" mode using the function selection knob.
- Observe the LED indicators on both units. They will light up sequentially, indicating the status of each wire pair.
- Interpretation of LEDs:
- Sequential illumination on both units: Correct wiring.
- No illumination for a specific pair: Open circuit.
- Multiple LEDs illuminating simultaneously or in an incorrect sequence: Short circuit or wiring fault.
- LEDs illuminating out of order: Reversed connection.

6.3 Telephone Line Testing
This function allows for checking the status of telephone lines (idle, ringing, talking) and identifying TIP and RING polarity.
- Connect the RJ11 alligator clip cable to the RJ11 port on the transmitter unit.
- Connect the alligator clips to the telephone line wires (TIP and RING).
- Turn on the transmitter unit.
- Observe the LED indicators and listen for audible signals to determine the line status:
- Idle: Specific LED pattern or continuous tone.
- Ringing: Flashing LED pattern or intermittent tone.
- Talking: Different LED pattern or tone.
- The device will also indicate the polarity of the TIP and RING lines.

6.4 Continuity, Voltage, and Polarity Tests
These tests are typically performed using the RJ11 alligator clip cable for various metallic conductors.
- Connect the alligator clips to the conductors you wish to test.
- Turn on the transmitter unit.
- Select the appropriate mode (e.g., "CONT" for continuity) using the function selection knob.
- Observe the indicators for continuity, voltage presence, and polarity.
7. Maintenance
7.1 Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use abrasive cleaners or solvents.
7.2 Battery Replacement
- Replace batteries when the low battery indicator appears or when the device's performance degrades.
- Always replace both 9V batteries simultaneously for optimal performance.
- Dispose of used batteries according to local regulations.
7.3 Storage
- If storing the device for an extended period, remove the batteries to prevent leakage.
- Store in a cool, dry place, away from direct sunlight and extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Batteries are dead or incorrectly installed. | Check battery polarity; replace batteries. |
| No signal during cable tracing. | Transmitter not connected, receiver volume too low, or cable is damaged. | Ensure proper connection, increase receiver volume, check cable integrity. |
| Incorrect cable test results. | Poor connection, damaged cable, or incorrect mode selected. | Ensure secure connections, inspect cable for damage, verify correct test mode. |
| Interference during tracing. | External electromagnetic interference. | Adjust receiver volume, try tracing from a different angle, or move away from strong electrical fields. |
